uC/OS-II, The Real-Time Kernel Atmel AT90/AVR Port for AVR-GCC READ ME FILE Acknowledgements: Most files in this port is based on the Atmel AVR port for the IAR compiler by Ole Saether. Without his work, porting to avr-gcc would have taken much longer. ------------------------------- AVR C COMPILER -------------------------------- 1) This version of the avr-gcc port is based on version 2.95.2 of avr-gcc. Versions of this can be found at : http://8bit.at/avr/ http://www.gwdg.de/~mrickma/avr/ http://home.overta.ru/users/denisc/ 2) It is assumed that the command line version of the GCC compiler is installed as described in the compiler documentation. --------------------------------- AVR PORT NOTES ------------------------------ 1) The port ZIP file should be unpacked, retaining the directory structure, into the "standard" UCOS-II directory : \SOFTWARE\uCOS-II\ After unpacking, you should have the following sub-directories: \SOFTWARE\uCOS-II\AT-AVR\GCC\SOURCE This directory contains the port source files. \SOFTWARE\uCOS-II\AT-AVR\GCC\TEST This directory contains the sample test code (i.e. TEST.C), as well as the makefile and BUILD.BAT which is used to compile, assemble and link the test code. \SOFTWARE\uCOS-II\AT-AVR\GCC\OBJ This directory contains the object files produced by the compiler and assembler. \SOFTWARE\uCOS-II\AT-AVR\GCC\LST This directory contains the 'listing' files produced by the compiler and the assembler. For the C compiler, these files contain the interleaved C source along with the assembly language code generated by the compiler. \SOFTWARE\uCOS-II\AT-AVR\GCC\DOC Contains this readme file and any other documentation that comes with the port. 2) The SOURCE directory also contains two modified linker script files, one for the At90S8515 CPU and one for the Atmega103 CPU. These files contains the necessary modifications to allow the .bss section to exist in the external RAM. They both assume a 32K RAM. If you have more or less, you should modify these scripts. 3) The port supports both the At90S8515 and the Atmega103 CPU's. The selection is done by commenting two lines in the makefile.Only the makefile and linker scripts should need to be changed for other CPU's. 4) TIMER0 overflow interrupt is used to generate the clock tick (see OS_CPU_A.ASM). 5) The code was tested on a STK200 using an AT90S8515 CPU. It was also tested on a mega103 CPU on a Opticompo board. I have not tried running the code on the AVR Studio Simulator, as first attempts crashed AVR Studio (Ver. 3.22). The port should work equally well on the AT90S4414 device as long as enough (external) RAM is provided. 6) You will also need the source code for uC/OS-II to recompile this port. The uC/OS-II source is included in Jean Labrosse's book "MicroC/OS-II, The Real Time Kernel".More information about uC/OS-II can be found at www.ucos-ii.com or www.micrium.com ----------------------------- REPORTING PROBLEMS ------------------------------ If you find a bug in this port, do not hesitate to report the problem to me (Jesper Hansen): 1) Through e-mail: jesperh@telia.com Make sure that the problem you are reporting is in this port and not in your application. Enjoy!! ------------------------------ AVR RELEASE NOTES ------------------------------ April 2, 2001: V1.00 ----------------------- 1) First release of AVR port for AVR-GCC
