We did use balenaEtcher to flash the linux wic on an SDcard, switched the version of tiboot3.bin for the general purpose version like described in https://dev.ti.com/tirex/explore/node?node=A__AdoyIZ2jtLBUfHZNVmgFBQ__am62x-devtools__FUz-xrs__LATEST&search=am62x for 8.6 and Linux bootet. Fine.
Then we tried with Android according to https://software-dl.ti.com/processor-sdk-android/esd/AM62X/08_05_00/docs/android/Overview_Flashing.html and pre-build binaries, but we could not boot from the SDcard we prepared, no console output. I tried with the tiboot3.bin that worked with the Linux card, but still no output.
So we used to Linux card to boot into u-boot, changed the environment, rebooted and successfully started fastboot, but then
./flashall.sh

Writing 'tiboot3' FAILED (remote: 'cannot find partition')
fastboot: error: Command failed
Does this fail because you can't do it with a wrong boot partition?
And ho can I find out why the original boot partition did not boot?
Thank you very much!
