AM2431: error in SOC_initialization

Hi, our expert is out of office until 4/6. Please expect a delayed response.

Hi,

My customer tried to run UART_Boot loader by referring below, and it seemed it worked well and there is no issue in their HW.

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_31/exports/docs/api_guide_am243x/TOOLS_BOOT.html#UART_BOOTLOADER_PYTHON_SCRIPT

They loaded uart bootloader using phython as below.

They can run their test application as below.

Thanks and Best Regards,

SI.

Hi SI,

Using the JS script is not the recommended way to set up the EVM or LP for software development. The recommended way is as following:

AM243x MCU+ SDK: EVM Setup (ti.com). Can you ask customer to try it? Thansk!

Best regards,

Ming

Hi Ming,

Do you mean below? 

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_31/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html

Do you mean they need to flash SBL on their board?

I already requested to flash SBL on their custom board and test it, but, in the meantime, I would like to check why SoC intiailization is not worked in their custom board and how I can guide them to connect CCS before flashing SBL.

Thanks and Best Regards,

SI.

Hi Sl,

The path for "sciclient_set_boardcfg" in the error log. Did you make any change in the script?

Hi Ankur,

No. They did not make any change in the script. They just insert 'print' to get log.

And there was no issue to run the script in the LP EVM. only occurred this error in their custom board.

In their custom board, they used 'XAM2431ASFGGAALX', but 'XAM2434ASFGGAALX' was used in LP EVM.

Do you think the resources difference between these two devices can cause this issue?

Thanks and Best Regards,

SI.

Hi SI,

You may be correct. AM2431 only has one R5F core, so the dsMCU_tsrage_halt may not work. Can you ask customer comment our=t that line in JS file and try again?

Best regards,

Ming

Hi Ming,

Thanks for the response. Could you please provide more details where should be modified?

I checked 'ti\mcu_plus_sdk_am243x_08_02_00_31\source\drivers\sciclient\sciclient_default_boardcfg\am64x_am243x\sciclient_defaultBoardcfg_rm.csciclient_defaultBoardcfg_rm.c' and found 'host_cfg_entries' structures managing resources. Should this structure and all related things be modified?

Other question is it seemed same file was used in SBL and why this SBL built using same file is working on customer's board.

it seemed they used prebuilt SBL file in the SDK.

Thanks and Best Regards,

SI.

Ming,

Could you please provide guide me how they can change it for AM2431?

I could not find other R5 cores initialization code than R5_0 in the load.js file. I found below resource allocation guide from MCU+_SDK as below, but I could not understand what should be modified for AM2431.

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_31/exports/docs/api_guide_am243x/RESOURCE_ALLOCATION_GUIDE.html

If you can provide more details on this, it would be very helpful.

Thanks and Best Regards,

Hi SI,

My mistake. I thought the dsMCU1_0_target_halt is for the R5F_1_0. It is actually for the R5F 0_0.

I do not know why the launch_dmsc.js will not work on customer board. If the SBL works for them, can use the sbl_null instead of the launch_dmsc.js? The launch_dmsc.js is not the recommended way for EVM or LP initialization anyway.

Best regards,

Ming

Hi Ming,

Thanks for your response.

Then, is there any other way to connect CCS without flashing SBL and launch_dmsc.js?

e.g. is it possible to run AM243x LP or EVM through CCS only using GEL files?

Thanks and Best Regards,

SI.

Hi SI,

Flashing sbl_null, then using CCS to halt R5F core or the using CCS with launch_dmsc.js are the only two ways to initialize the AM243x LP I know of.

Best regards,

Ming

Hi Ming,

The problem to flash sbl_null is they need to build flash driver for their custom board and they also have an issue in this.

Is there any way to load sbl_null through JTAG?

Thanks and Best Regards,

SI.
