I am trying to run Android OS on DB410c and following this link for the same.
I have observed that from 20.02 release onward, tz.mbn was not getting flashed using fastboot in bootloader for Android because of the size issue, and getting below error:
Sending 'tz' (591 KB) OKAY [ 0.023s] Writing 'tz' FAILED (remote: 'size too large') fastboot: error: Command failed
I have checked bootloader from 20.02 (dragonboard-410c-bootloader-emmc-aosp-137.zip), 20.07 (dragonboard-410c-bootloader-emmc-aosp-145.zip) and 20.11 (dragonboard-410c-bootloader-emmc-aosp-150.zip) release and getting same issue with all.
In 19.01 (dragonboard-410c-bootloader-emmc-aosp-110.zip) bootloader, there is no issue.
I am trying to run Android from Stable Snapshot 99 (https://www.96boards.org/documentation/consumer/dragonboard/dragonboard410c/downloads/android.md.html) and also want to use latest bootloader images. So can you please provide updated bootloader package or gpt image with increased size.
