Original question:

TDA4VM: [DRA821U] Board reset after around 10 minutes

TDA4VM: Reset reason when board reset automatically

Part Number: TDA4VM


Tool/software:

Dear TI.

We made a test board and it reset automatically within 10 minute.

When it reboot with SD mode.

In uboot prompt, WKUP_CTRL_MMR0_CFG0 at 0x43018178 is like below.

> md.l 0x43018178 1

43018178: 00010001

Is there another register which I could check why this reset is triggered ? (Watchdog or something)

Strangely, when it boot in EMMC mode, it can not reboot but lock-up (console does not respond)

I suspect that reset was triggered automatically, but it could not reboot.

When I executed reboot command in linux console, it could not reboot.

FYI, I'm using ti-processor-sdk-linux-j7200-evm-09_02_00_04.

    Hi Lee,

    Just a couple of questions to ask:

    1)Are you using a custom j7200 board or TI j7200 evm.

    2)If using a custom board,what are the changes you made.

    Dear TI,

    I'm using  a custom j7200.

    I'll ask our HW guy to summarize changes.

    And I observed that nRSTOUT pin of TPS6594 is triggered when reboot happened.

    In which condition nRSTOUT  is triggered ?

    Do you know how to disable nRSTOUT in TPS6594 ? Since reboot happens too frequently so we can not verify other functions.

    BR
