Hi @balbes150,
I flashed Debian 5.77 to my SDcard. It booted ok with my new TX3 mini (type A).
But now, when I ejected the SDcard from box, I can't boot to Android anymore. It stucked at device's booting logo.
I dont't install Armbian to eMMC. Just boot from SDcard and than eject it. Currently, I still can boot to SDcard, but Android is not. The only way to back to Android is re-flash the Android firmware.
I used "dmesg | grep mmc" command to check my device is eMMC or NAND, I found this: mmc2: new high speed SDIO card at address 0001
Can you help me? How to dual boot?
