IMPORTANT NOTE -------------- This software release (Release) is an engineering release. This software has not been through formal release testing, and associated documentation has not been updated to reflect changes in this Release. The Release is for evaluation only, is not intended for qualification or use in production, and is provided “AS IS” without any warranty from Freescale Semiconductor. Freescale may change the Release without notice. INTRODUCTION ------------ This document will describe the procedure for flashing a Windows Embedded CE 6.0 bootloader (EBOOT) and OS image onto the MX27ADS. This procedure uses the ADS Toolkit (ATK) with serial connection to the PC) and Microsoft Visual Studio with Platform Builder for CE 6.0. SYSTEM REQUIREMENTS ------------------- ADS Toolkit (ATK) software revision 1.3 or later Serial DCE-DTE cable MX27 ADS Kit ver 2.6 PREPARING FOR FLASHING ---------------------- 1. a. Install ADS toolkit software on PC b. Install Visual Studio 2005, Visual Studio SP1 on PC c. Install Windows Embedded CE6, CE6 2006 Yearly update, SP1 for Windows Embedded CE6 d. Install additional CE 6 updates: 2008 monthly updates to June 2007. e. connect serial cable from UARTA of MX27ADS to PC's COM port f. exit any other terminal program using that COM port of PC 2. Configure ADS for ATK Download: a. Power off the ADS b. return ADS to factory settings (See ADS User Guide) c. Set bootmode switch S18 positions 1-4 (BOOT0 to BOOT3) all switched ON d. power on ADS e. press reset switch on CPU board 3. Configure ADS Toolkit for download a. launch ADS Toolkit executable b. select type of i.MX [i.MX27_T02] c. leave Device memory initial as DDR d. click Next e. select Flash Tool and click Go f. select Flash model NOR S71WS256ND0 g. select Program h. browse to demo Image file "eboot_nor.nb0" i. click "Program" 4. In case of failure to download/program, then repeat procedure from 2.e 5. When programming succeeds, reset ADS for booting from NOR: a. power off ADS b. CPU switch S18 to 1=off 2=on 3=off 4=on 6. connect debug console or terminal program on PC, a. via serial cable to ADS EXT UART b. select terminal baud rate 115200 bps, N-8-1 c. power on ADS, use to break into bootloader You may now follow the EBOOT procedure below for downloading and flashing NK.bin to NAND memory. BOOTING FLASHED IMAGE --------------------- 1. Configure the ADS board for external NOR boot. This is accomplished by configuring the S18 BOOT switches on the MX27 CPU board as follows: SW18-BOOT0 = OFF SW18-BOOT1 = ON SW18-BOOT2 = OFF SW18-BOOT3 = ON Serial console is on EXT UART. 2. Power on the ADS 3. EBOOT will begin to execute and display messages to the terminal window. The EBOOT configuration will be erased during the flashing sequence. EBOOT will automatically display the configuration menu. 4. Verify that a valid MAC address is shown in the the EBOOT menu. If not, use menu to enter the MAC address indicated as "EXT Ethernet" on the sticker on the ADS board. 5. Continue selecting the Autoboot menu option until "NK.bin from NAND" is selected. 6. If desired, you can reduce the time before booting using the Boot Delay menu option. 7. Save the configuration using the EBOOT menu. DOWNLOADING VIA PLATFORM BUILDER -------------------------------- 1. Launch Visual Studio with Platform Builder for Windows Embedded CE 6 2. Configure Platform Builder to download to the target board This is only necessary when NAND flash has been erased or switching between NOR and NAND a. select Target -> Connectivity Options b. click Core Service Settings, - Download Image Always - KITL enable, clear memory c. click Kernel Service Map - Download [Ethernet] - Transport [Ethernet] - Debugger [KdStub] d. Click Download Settings 3. in EBOOT Terminal window, select "D" for download - MX27 should send BOOT messages - device name should show up in Active Devices - click device name, then OK - click Apply, click Close - click Target -> Attach Device 4. Platform Builder will ask for image. Navigate to nk.bin and select. 5. download should begin. Follow other bootloader instructions until NAND is programmed and message "Spin Forever..." is displayed 6. Reset the MX27 and EBOOT will run from NOR, launching NK.bin from NAND. BOOTING FROM NAND ------------------- To load bootloader into NAND, after step 5 above you may continue to use NOR eboot to download EBOOT into NAND 6a. close nk.bin in Platform Builder (disconnect from device) 6b. Attach device in Platform Builder again. When Platform Builder requests image, select xldr.bin 6c. Reset the ADS and break into bootloader 6d. Select 'D' to download xldr.bin and follow instructions until "Spin Forever..." 6e. Close xldr.bin in Platform builder (Disconnect from Device) 7. Repeat above procedure for eboot.bin 8. Power off ADS and reconfigure ADS board for external boot from NAND. This is accomplished by configuring the BOOT switches on the MX27 CPU board as follows: SW18-BOOT0 = OFF SW18-BOOT1 = OFF SW18-BOOT2 = OFF SW18-BOOT3 = ON 9. Ensure serial console is connected to EXT UART for this NAND eboot bootloader console. 10. Attach device in Platform builder (select nk.bin as image). This will permit KITL connection. 11. Power on ADS and hit the reset button on the MX27 CPU board to launch EBOOT again. 12a. If no key is pressed within the specified boot delay, EBOOT will automatically jump to the OS image in NAND flash. 12b. Alternatively break into bootloader and launch flash image with "L" 13. Future downloads can be done using EBOOT from NAND (no CPU switch / jumper reconfiguration) 14. When nk.bin image is built (Make Run Time Image, "makeimg") with IMGFLASH not set, then image will be downloaded to RAM instead of flash. Either NAND or NOR EBOOT can be used. ============= end of readme.txt ============
