AM6442: AM64 SoC Initialization Using CCS Scripting, does not work on EVM and custom board

Part Number: AM6442

Tool/software:

Hi all,

we have a custom board with an AM6442 and flash (MX25UM25645). In order to get the flash working we want to run the flash diagnostic code.

In order to load and run/debug code we need to run the "SOC Initialization Using CCS Scripting" first. (https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/10_00_00_20/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html#EVM_SOC_INIT_NOBOOT_MODE)

On our custom board the procedure does not work, but it also does not work on the am64x-evm board from TI. Here is the output from the am64x-evm board:

How can we get our device initialized with the CCS Initialization procedure?

We are aware of this thread (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1106960/am6442-load-dmsc-and-ddr-init-scripts-with-tmds64dpevm), but we need to get the flash working first though.

Are there other ways to get the SoC initialized and into debug mode? Is it possible to run the sbl_null directly via uart instead of the sbl_uart_uniflash?

Some further details:

AM64X-EVM number: PROC101C(004)

Our custom boad: has no SD card, custom flash (MX25UM25645G), emmc is swissbit, AM6442BSFGHAALV), custom DDR, ...

SDK version: 10.0.0.20

Let me know if you need further information.

Best regards,

Ergin

Hi Ergin,

Thanks for your query.

I have checked the above and able to replicate your issue.

It seems like the sciclient_ccs_init.release.out binary is corrupted and not working as expected. I have checked the binary and figured out that it is failing at sciclient_abiCheck API call.

Can you please try with the below provided binary?

Binary - sciclient_ccs_init.release.out

The above binary is working as expected on TI EVM. Please let us know if the above works for you as well.

Regards,

Tushar

Hi Tushar,

With the given file it worked on the evm and also our custom board. Many thanks!

We used the procedure described in this video from the other thread with your file, in case someone else wonders. (https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1329122/lp-am243-initialization-script-is-not-working)

Out of curiosity, what kind of file is it that you supplied? Is it from another SDK version?

Best regards,

Ergin

Thanks for the confirmation.

The binary provided above is from the same SDK version(i.e. v10.0). I have rebuilt the binary from the sciclient_ccs_init example located at path ${MCU+SDK}/examples/drivers/sciclient/sciclient_ccs_init.

As mentioned in earlier replies that the sciclient_abiCheck is failing for the default binary because it is not rebuilt using the SDK v10.0.

Hope this information helps.

Tushar
