TDA4VM: Replace custom mcu1_0 code for spl startup, but the startup fails

Hi,

May I know is there any updates?

Thanks and regards,

Cherry

Hello Cherry,

The MCU1_0 is responsible for device management. Once it finishes executing SPL it loads the device manager binary on to itself. The prebuilt binary should have worked ideally. Can the customer share the steps on how they are creating the tispl.bin.

Hi Keerthy,

sdk:ti-processor-sdk-rtos-j721e-evm-08_01_00_13

自研板。

我使用mcusw/mcuss_demo/profiling/can的 demo,开发了mcu1_0的代码，在ccs中可以正常发can报文，现在想通过a72启动（spl启动），但是启动失败了。

我制作tispl.bin的步骤为:

1,编译can demo.

2, 将can_profile_app_freertos_mcu1_0_release_strip.xer5f 作为编译u-boot-a72 的DM.

3,编译u-boot。

4,将u-boot_build/a72中的tispl.bin拷贝到sd卡中的BOOT分区。

5，插入SD卡，并重新上电。

然后就出错了，错误内容如上述。

Hello,

Sorry this is definitely not clear.

Also You can check the components of tispl.bin by below command:

'dumpimage -l tispl.bin'

Best Regards,
Keerthy

hi, This is my tispl.bin：

Hi,

DM binary is 282648 bytes. Can you confirm the size of default DM binary under the prebuilt-images folder\?

First try with the default prebuilt binary of DM in the SDK.

Hi, Keerthy

I want to try to use it myself: ti-processor-sdk-rtos-j721e-evm-08_01_00_13/mcusw/mcuss_demos/profiling/can demo, let it compile to tispl.bin, and then start with a72, can you tell me what I need to do?

hi, Keerthy,

May I know is there any updates?

Sorry. I did now quite follow your boot flow. Please elaborate.

In any case you need to try to check if the default DM binary works well.
