AM623: Fail to reboot

Part Number: AM623
Other Parts Discussed in Thread: SK-AM62B-P1, AM625

My AM623 can boot normally, but can't reboot (use terminal) ! However, the EVM (SK-AM62B-P1) can boot and reboot (use terminal) successfully!

the boot message is like below file:

Please give me some directions or suggesstion, thanks.

  • Hi Johnny,

    Do you boot the board from SD card? Does your board connects the AM623 SoC reset pin to the SD card cage power supply? The SD card power supply has to switch from 1.8v to 3.3v for reboot to work.

  • Do you boot the board from SD card?
    Yes, I boot from SD card.

    Does your board connects the AM623 SoC reset pin to the SD card cage power supply?
    I'm not sure about this, but I try type reboot on terminal with EVM board (SK-AM62B-P1) and found there is no signal change at RESET_REQZ and could reboot sucessfully.

    In addition, I find that system can't find watchdog device node (/dev/watchdog) on AM623, but can be found on AM625(SK-AM62B-P1).

    Is this the issue about reboot?

  • Hi Johnny,

    Please check the SK EVM schematics SD CARD RESET section, the SoC RESETSTATz signal is connected to the SD card load switch.

  • I have checked my board connects the AM623 SoC reset pin to eMMC because desired main boot mode is eMMC.

    Furthermore, I find that my AM6231ASGGHAALW does not support PRU. I try disabling PRUSS on dts and finally could reboot!

    &pruss {
            status = "disabled";
    };

  • Hi Johnny,

    I am glad the issue is resolved. Thanks for the update.

    I noticed the PRUSS errors in the kernel boot log, and I know that is because the device you use doesn't have the PRUSS module. But I won't know it would cause reboot failure. I thought to tell you to disable pruss device tree node later once we fixed the reboot issue, so you won't get distracted. Now I know the pruss init failure would cause reboot problem. Thanks.
