I was using bionic-minimal-rock64-0.6.33-211-arm64.img.xz, I upgraded to the current stable release 0.6.41-227 by "apt upgrade" today, then my rock64 is unable to boot now. I don't have a working usb serial console adapter, so I don't know the boot message.
I am using an emmc module, I tried the "jumper pull" method (pull emmc jumper 2-3 seconds after applying power) many times to boot the sdcard, but have never succeed. I can boot the sdcard (armbian) only when the emmc module removed from the socket. I don't know how to make my rock64 working with the emmc module again.
