TMDSLCDK6748: Flashing Problem

Part Number: TMDSLCDK6748
Other Parts Discussed in Thread: OMAP-L138, OMAP-L132

Dear All,

I have a problem flashing TMDSLCDK6748 development kit.

Following is my scenario:

(1) On CCS  Version: 10.2.0.00009, I build and run "GPIO_LedBlink_lcdkOMAPL138_c674xTestProject" example project that I got when installed "ti-processor-sdk-rtos-omapl138-lcdk-06.03.00.106-Windows-x86-Install.exe". I see how D4 and D5 toggling according to the demo. Picture below is how the target is connected in CCS

(2)  I use AIsgen V1.13 to create d:\ais.bin as shown in the below figure

Nand Flash is 16bit width.

Firsts questions.

- Should I Configure any other field? Is there any .cfg file that I can "Load" AISgen  with the correct configuration for TMDSLCDK6748 development kit.?

(3) I have dowloaded "OMAP-L138_FlashAndBootUtils_2_40" and navigate to ...OMAP-L138_FlashAndBootUtils_2_40\OMAP-L138\GNU and open a CMD windows.

I connect TMDSLCDK6748 board to the PC and set switches to boot on UART2.

Then I use command:

sfh_OMAP-L138 -erase -targetType C6748_LCDK -flashType NAND -p COM4 (Operation completed successfully.)

Then I flash NAND

sfh_OMAP-L138 -flash_noubl D:\ais.bin -targetType C6748_LCDK -flashType NAND -p COM4

(4) I set switches in TMDSLCDK6748 board to NAND boot and Power On board but I dont see that leds are blinking so, I think board is not booting correctly.

In CCS I also run Scripts> Diagnostics>Run_All, after loading a GEL (C:\ti\ccs1020\ccs\ccs_base\emulation\boards\evmomapl138\gel\OMAPL1x_debug.gel) and can assure it is booting NAND 16.

Please could yo tell me if I am doing something wrong?

If you need further information from my side, please dont hesitate to ask for it.

Thanks in advance,

Joaquin.

    Dear all,

    Finally, after read many posts, I have conclude that there was a file called "C6748_LCDK_AISGen_Config.cfg" that you can use with AISgen tool to Load de TMDSLCDK6748 board configuration. Just use File>Load Configuration in AISgen tool.

    This file can be found in the installation path of the AISgen tool, in my case "C:\AISgen_d800k008_Install_v1.13\AISgen for D800K008\cfg_files".

    In my opinion, just as a simple feedback for TI team, document SPRAB41F "Using the OMAP-L132/L138 Bootloader" should comment this in any point. At least for me, it would have saved a lot of time.

    Thanks anyway all for your great support.

    Regards,

    Joaquin.
