ST Reference Firmware STi5500 DVB Reference Driver Release 4.1 26 January 1999 COPYRIGHT (C) ST Microelectronics 1999 ########################################################################### ### FEATURES ### ########################################################################### The following features which has been tested are : Decoding MPEG-2 / DVB live streams Decoding MPEG-2 elementary streams (files) Compatible mode (3 frame buffers) B on-the-fly mode (2 frame buffers) (with STi5500 version DEC only) 3:2 pull-down mode Pan&scan (note that STi5500 only supports horizontal pan) Channel change (for testtool) Intensive zapping (channel change in loop) PAT/PMT extraction Teletext (VBI and STB modes) UART interface (for debug) Code on SDRAM only (DRAM not used) OSD function with usif interface Tuner management via I2C link Dynamic Acquisition of PAT and PMT (when tuning frequency) Boot from Flash Eprom with Code on DRAM Boot from Flash Eprom with Code on SDRAM only Tools for flashing the DVB reference software The following features ought to be done in next release : Debug of SmartCard driver The following feature is not supported by this software : Decode of video streams with Frame and Field images in the same sequence on B on-the-fly mode (hardware bug with no work-around for the moment). IMPORTANT : =========== If you do not use an Eval0199 (Front-end board) connected to the Eval5500 I2C interface, do not forget to comment the call to 'tuner_init();' function in main.c file (line 860) -> otherwise the program hangs when searching the Eval0199 board.. The tables belowed presents the features which have been tested and validated on a DVB setup or an elementary stream (audio and video), depending on the software configuration : Compilation switches (to be defined in 55refcfg.h file : #1 : BOOT_ON_SDRAM #2 : BUILT_FOR_16MBIT #3 : BUILT_FOR_32MBIT #4 : B_ON_THE_FLY #5 : NTSC_STANDARD #6 : PAL_STANDARD #7 : ENABLE_AVSYNC #8 : DECODE_ELEMENTARY_STREAM (a cross indicates that the corresponding compiler switch has been fitted) ------------------------------------------------------------------------------- | #1| #2| #3| #4| #5| #6| #7| #8| COMMENT | ------------------------------------------------------------------------------- | | | X | | | X | | | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding DVB live without | | | | | | | | | | audio/video synchro, with PAL display. | ------------------------------------------------------------------------------- | | | X | | | X | X | | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding DVB live with | | | | | | | | | | audio/video synchro, and PAL display. | ------------------------------------------------------------------------------- | | | X | | | X | | X | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding elementary streams| | | | | | | | | | without audio/video synchro, with PAL | | | | | | | | | | display | ------------------------------------------------------------------------------- | | | X | X | | X | | | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding DVB live without| | | | | | | | | | audio/video synchro, with PAL display. | ------------------------------------------------------------------------------- | | | X | X | | X | X | | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding DVB live with | | | | | | | | | | audio/video synchro, and PAL display. | ------------------------------------------------------------------------------- | | X | | X | | X | | | Code and data on DRAM, 16MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding DVB live without| | | | | | | | | | audio/video synchro, with PAL display. | ------------------------------------------------------------------------------- | | X | | X | | X | X | | Code and data on DRAM, 16MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding DVB live with | | | | | | | | | | audio/video synchro, and PAL display. | ------------------------------------------------------------------------------- | | | X | X | | X | | X | Code and data on DRAM, 32MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding elementary | | | | | | | | | | streams, without audio/video synchro, with | | | | | | | | | | PAL display. | ------------------------------------------------------------------------------- | | X | | X | | X | | X | Code and data on DRAM, 16MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding elementary | | | | | | | | | | streams, without audio/video synchro, with | | | | | | | | | | PAL display. | ------------------------------------------------------------------------------- | X | X | | | | X | | | Code and data on SDRAM, 16MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding DVB live | | | | | | | | | | without audio/video synchro, and with PAL | | | | | | | | | | display. | ------------------------------------------------------------------------------- | X | X | | | | X | X | | Code and data on SDRAM, 16MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding DVB live | | | | | | | | | | with audio/video synchro, and PAL display. | ------------------------------------------------------------------------------- | X | X | | | | X | | X | Code and data on SDRAM, 16MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding elementary | | | | | | | | | | streams, without audio/video synchro, with | | | | | | | | | | PAL display. | ------------------------------------------------------------------------------- | | X | | | X | | | X | Code and data on DRAM, 16MBIT of SDRAM, | | | | | | | | | | compatible mode, decoding elementary | | | | | | | | | | streams with 3:2 pull down, without audio/ | | | | | | | | | | video synchro, with NTSC display. | ------------------------------------------------------------------------------- | | X | | X | X | | | X | Code and data on DRAM, 16MBIT of SDRAM, | | | | | | | | | | B on-the-fly mode, decoding elementary | | | | | | | | | | streams with 3:2 pull down, without audio/ | | | | | | | | | | video synchro, with NTSC display. | ------------------------------------------------------------------------------- By default, The following compiler switches are defined in file main\55refcfg.h : -

STI5500_VERSION_D By default, CONFIG = CODE_ON_SDRAM_32M in file hw.cfg. ########################################################################### ### BRIEF USER GUIDE ### ########################################################################### Setting up the tree Unzip the archive, don't forget -d option if using ms-dos line's pkzip. You should get a tree, see FILES LIST section for its contents. Configuration There are 2 types of configuration: -hardware configuration in file main\st5500.h : define the version of the STi5500 you are using - you must define one and only one version (STI5500_VERSION_A, STI5500_VERSION_B, STI5500_VERSION_C or STI5500_VERSION_D). -software configuration in file main\55refcfg.h : define your i/o setup -> UARTIO, UNHOSTED, STREPORT Code on DRAM or SDRAM -> CODE_ON_SDRAM PWM initial values -> PWM_CONTROL_LARGER_VALUE_FASTER_CLOCK, PWM_REBASING TV standard -> PAL_STANDARD, NTSC_STANDARD type of audio DACs -> _16BIT_AUDIO_DAC amount of SDRAM -> BUILT_FOR_16MBIT, BUILT_FOR_32MBIT B on-the-fly feature or not -> B_ON_THE_FLY Input from link or files -> DECODE_ELEMENTARY_STREAM traces setup -> xxx_DEBUG compiler switches Building the tree The tree was developped using Microsoft Make v1.4 and v1.5, available at the following address: ftp://ftp.microsoft.com/Softlib/MSLFILES/NMAKE15.EXE GNU make (v3.75 or higher) may also be used though it has been known to fail at linkage on some PCs. GNU make is available at: ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/mak3761b.zip If you want to use another make utility, change the MAKE field in top directory's makefile. Connecting the board See archive connect.zip in the same directory. Programming/Booting the STi5500 DVB Reference Software : Four batch files are provided for comfort, they are: - gui.bat : boots and launches the GUI debug interface with main.lku executable file - nogui.bat : boots without the GUI with main.lku executable file (with -v option) - flash.bat : burns the Flash Eprom with main.bin executable code - debug.bat : Debugs the main.bin executable from ROM +-----------------------------------------------------------------------+ | 5500 ref v4.1 was developped using DCU toolset v1.6.2 | | st20cc : v2.55 (13-Oct-19***) | | st20libr : v3.3 (8-Jun-19***) | | st20run : v1.6.2 (19-Oct-19***) | +-----------------------------------------------------------------------+ +-----------------------------------------------------------------------+ | ****** IMPORTANT NOTES ****** | | If you previously used DCU 1.5 or 1.5.1, recompile all the libraries | | with DCU 1.6.2 (no compatibility) | | To compile this release with DCU toolset v1.5 or 1.5.1, remove the | | compiler option "-fdisable-device" in file make.inc | +-----------------------------------------------------------------------+ ########################################################################### ### WHAT'S NEW IN THIS RELEASE ### ### (comparing with Release 4.0) ### ########################################################################### GENERAL - Compiler switch UARTIO is defined by default - Added debug_rom_reset function in hw.cfg file in order to debug STi5500 DVB Ref ROM version - Added c2_5500ref_rom function and c2_5500ref function is renamed c2_5500ref_lku in main.cfg file - modified ST5500InitPLL function in order to set-up all the clocks (VCO, SMC, PCM, LINK, SDRAM) in st5500sd.cfg file - Added commands cflash.x and flash.x to clean and build the Flash Eprom Burner Tool in file makefile - Added commands cload.x and libload.x to clean and build the Loader library (used for ROM exe file) in file makefile - Added ROMFLAGS, CFG_FILE variable + main.bin file generation in file makefile - Added debug.bat batch file to debug from rom (main.bin file) with DCU toolset 1.6.2. - Bug fixed in c2MemoryInit function (in file hw.cfg) -> problem in position of '{' DEVELOP directory : - Added CodeExe extern variable in order to know the boot origin (from JTAG : LKU file or from ROM : BIN file). At bootstrap, the 32-bit pointed by address 0x8000000 (SRAM_BASE) are set with 0x00554b4c ("LKU" string) if it is an LKU file (see c2def function in hw.cfg file), or set with 0x004d4f52 ("ROM" string) if it is a boot from ROM (see c2_5500ref_rom function in main.cfg file) MAIN directory: - Added private macro "print" in main function (file main\main.c) - kernel_start function is called in init_system function (file main\main.c) - InitPll and InitSdramInterface functions are called only if CODE_ON_SDRAM is not defined, these functions are no more "static" (file main\main.c) MPEG directory: - Two bug fixed concerning the streams "fields only" decoding in compatible and B on-the-fly mode (file mpeg\vid_intr.c) - Added some traces to follow the picture actually displayed when a done VSYNC (TOP or BOT) (file mpeg\vid_intr.c) - Added "Pipe hangs" workaround from Serge Dulhoste in vsync_interrupt_routine function (file mpeg\vid_intr.c) - Added AnchorFrameNumber management in B on-the-fly mode, and Modified PID interrupt : B-picture are skipped if AnchorFrameNumber is equal to 1 -> no more artetfacts when starting on open-GOP (file mpeg\vid_intr.c) - Bug fixed in mpeg_process_user_data_header and NextStartCode functions (file mpeg\vid_head.c) some video interrupts were masked by reading VID_ITS register - Bug fixed in mpeg_process_picture_ext_header function (file mpeg\vid_head.c) : the picture extension CPY_RIGHT_EXT_ID, PICT_SPATIAL_SCAL_EXT_ID, and PICT_TEMPORAL_SCAL_EXT_ID are now parsed - Added RegisterChannels function (file mpeg\mpg_debg.c) to store the current channels PIDs (video, audio, and PCR), these registered channels are used in automatic zapping function - Added new testtool command to select a registered channel (file mpeg\mpg_debg.c) - Bug fixed in file mpeg\mpegi.h : CPY_RIGHT_EXT_ID = 0x4 (and not 0x3) -Bug fixed in SetupRecons function when setting the bit OVW in VID_TIS register : changed test condition in compatible mode and not used in BOTF mode - Added new testtool command which allows to enter new Video and/or Audio file streams when DECODE_ELEMENTARY_STREAM compiler switch is defined. The name of the proposed files are read from video.dat and audio.dat files. The command can be called at anytime. PTI directory: - Bug fixed in pti_set_buffer function (handle of NULL pointers) TABLES directory : - Added a timeout for any wait on the semaphore pat_got_section if TIMEOUT_ENABLED is defined (file \tables\pat.c) - Removed task_delay(1000) in tables_get_pat_current_version function (file \tables\pat.c) - Bug fixed when TIMEOUT_ENABLED is defined : semaphore pmt_got_section ought to be initialised with function semaphore_init_fifo_timeout (file \tables\pmt.c) - Bug fix in tables_pmt_section_retrieve function : call to "pti_clear_pid(pmt_slot)" instead of "pti_clear_pid((pid_t)pid)" (file \tables\pmt.c) - Added a timeout for any wait on the semaphore pmt_got_section if TIMEOUT_ENABLED is defined (file \tables\pmt.c) - Removed task_delay(1000) in tables_pmt_section_retrieve function (file \tables\pmt.c) FLASH\BURNER directory : - Added Flash Burner tool in the Flash\Burner directory. The tool flashprg.lku can be produced with the "main" makefile (enter make flash.x) or directly with the file 5500ref\flash\burner\makefile - All information can be found in the file 5500ref\flash\burner\readme.txt - added flash.bat batch file to burn main.bin binary file in the Eval-5500 Flash eprom. FLASH\LOADER directory : - A new library loader.lib is delivered with this release in order to run code on SDRAM with boot from Flash Eprom. Comparing to the loader.lib delivered with the DCU toolset 1.6.2, this library has been minimised and uses only two C-modules : romload.c romload2.c - only the file romload.c has been modified by adding functions to initialise the PLL and the SDRAM interface at the bootstrap level : InitPllFromRom InitSdramInterfaceFromRom ########################################################################### ### MAIN ### ########################################################################### In file main\main.c you will see various inits for various subsystems. You can comment un-needed calls, however some subsystems may require others to be initialized. It is advised not to change the order of the calls. ########################################################################### ### PTI ### ########################################################################### Implemented features: all PTI API functions except boolean pti_set_stc_to_next_pcr( void). Please see text file pti\pti_info.txt for details and programming guidelines. ########################################################################### ### TELETEXT ### ########################################################################### Please see text file teletext\ttx_info.txt for details and programming guidelines. ########################################################################### ### MPEG ### ########################################################################### User guide : TO PLAY A TRANSPORT STREAM FROM A Link IC / MTS100 - if your Link IC/MTS100 is configured to deliver serial data MSB, simply enter the command at the testtool prompt, or enter comman ... ...
