#3. In SK9.3 user guide, removed Power Management section. Below post was working on SDK9.3, I checked SDK9.3 .config, CONFIG_WKUP_M3_RPROC=m  and CONFIG_WKUP_M3_IPC=m is set in default. then applied 2 patches from this thread.

    Hello Tony,

    for #1, just to confirm, this is with the "default-image" from https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-AM335X ?

    Those commands work just fine on my board, but it looks like I'm running an early access version of SDK 9.3. I'll download that file and try it out on my side tomorrow.

root@am335x-evm:/home# ls
root  weston
root@am335x-evm:/home# cd ..
root@am335x-evm:/#

    after we get through #1, I'll reassign this thread for another team member to discuss #2 & 3.

    Regards,

    Hello Tony,

    Thanks for the ping. I am unable to replicate your observations.

    I downloaded file 

    tisdk-default-image-am335x-evm-09.03.05.02.wic.xz  — 496838 K

    from

    https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-AM335X

    And ran the image on the AM335x BeagleBone Black:

    I recreated with a 32GB SD card, it is OK now.

    Originally I create with a 8GB SD card with balenaEtcher, but failed.

    Then create with another 8GB SD card, succussed and can boot, but behave abnormal as the post.

    Now create with a 32GB SD card, works.

    Hello Tony,

    Glad to hear that things are working now!

    That is strange, since it looks like the filesystem only takes up a bit more than 4GB on the SD card (I am using a 16GB SD card). I might have seen something like this before but I am not sure if we ever root caused what was going on... I will ask around. If I get any updates, I will update the e2e thread.

    Regards,

    Nick
