Part Number: AM5728
Other Parts Discussed in Thread: ADS7846

Tool/software: Linux

Hi, TI and every one,

I'm testing AM5728 EVM made by China using ti-processor-sdk-linux-am57xx-evm-04.03.00.05-Linux-x86-Install.bin

Normally, that booting is good, but sometimes failed as below:

    Hi, Aither,

    When the board failed, was it running exact the same configuration as when it booted successfully? Is the successful one not running any DSP application or there something else different from the failed one?

    There was a similar failure case on a custom board and was resolved by fixing its power supply issue. I am not sure if that applies to this case. Here is the links for your reference:
    e2e.ti.com/.../2509878, and
    e2e.ti.com/.../555762

    Hi, Re

    Thanks very much for your answer.

    I also think as you, recheck the board, then again test.

    Thanks

    Best Regards.

    Hi,Rex

    I have the same solution as Aither. I am using SDK-RT 4.03.

    But it only happen at I use openvx firware. which is high probability let the system hang or crash.

    I found some release notes about this,can you give me some advices?

    LCPD-9481 P4-Low Sometime the system hangs while loading the rpmsg rpc modules

    LCPD-4855 P4-Low [rpmsg 2015 LTS] IPC: Board hangs when an MMU fault occurs in the first message

    LCPD-4699 P4-Low rpmsg-rpc: kernel crash during error recovery with dynamic debug traces enabled IPC

    PLSDK-1712 am572x-idk, am572x-evm openvx test hangs on AM572x-GP and AM572x-IDK platform

    Thanks.

    Hi, CY,

    Let's work in the thread you created, e2e.ti.com/.../2614065, which happens when running OpenVX and is different from this one.

    Thanks!
