Part Number: AM2431
Other Parts Discussed in Thread: UNIFLASH, LP-AM243

Hello,

I was following the getting started in the url below.

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/SDK_DOWNLOAD_PAGE.html

0. SoC on custom board is AM2431BSDGHIALV.

Using the XDS110 emulator I have, JTAG test connection and connection with R5F is successful.

1. But, The following commands in the Flash SOC Initialization Binary part do not work properly. (in win 11)
>python uart_uniflash.py -p COM4 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg

[ERROR] XMODEM send failed, no response OR incorrect response from EVM OR cancelled by user,
Power cycle EVM and run this script again !!!

2. And below is the contents of the default_sbl_null.cfg file.

--flash-writer=sbl_prebuilt/am243x-evm/sbl_uart_uniflash.release.hs_fs.tiimage

--file=sbl_prebuilt/am243x-evm/sbl_null.release.hs_fs.tiimage --operation=flash --flash-offset=0x0

3. I can set all Boot mode [0:15] on my custom board, and I set it to UART Boot mode as shown in the picture below in the URL above.

4. The current situation is that when booted to UART Boot mode, "C" is continuously output to the connected COM4 and the following information is obtained through the string other than "C".

> python uart_boot_socid.py -d am243x -f data.txt

Hi Seong Chang Kim,

If your device is on a custom board, is it verified for flash configurations ?

It is important that the flash is verified on the custom board with these steps - https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/CUSTOM_FLASH_SUPPORT_GUIDE.html

If the flash is verified, reuse the syscfg/driver changes for uniflash after the steps mentioned in the above section is completed.

There is another FAQ which explains more about the flash integration in custom devices - https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1230063/faq-mcu-plus-sdk-am243x-faq-how-to-debug-develop-migrate-the-flash-driver-for-custom-flash-on-non-ti-evm-ospi-xspi

I hope this resolves your problem.

Best Regards,
Aakash

The custom board has only the same QSPI flash (S25HL512TFAMHI010) soldered as LP-AM243. Does the flash memory still need to verify?

What is the relationship between the below command not working and verifying the flash?
python uart_uniflash.py -p COM4 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg

I tried to load after building opi flash diagnosis example code, but the following error occurred.

MAIN_Cortex_R5_0_0: Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x40: (Error -1065 @ 0x40) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.12.0.00150)
MAIN_Cortex_R5_0_0: File Loader: Verification failed: Target failed to write 0x00000000

Hi Kedia,

We have another problem.
Only one of the two image files (sbl_uart_uniflash.release.hs_fs.tiimage) of default_sbl_null.cfg is loaded, while the other (sbl_null.release.hs_fs.tiimage) is not loaded.
Have you ever had this problem?
What should I do?

Hi Seong Chang Kim,

It looks like there is some failure with UART UNIFLASH. As recommended, please test the flash configuration with flash_io example in dev boot mode.

I hope this helps.
