hi Quectel’s R&D,
I’m using AG55xQ and facing with enter reboot to bootloader mode to upgrade systemfs via fastboot.
Below is screenshot. Left screen is uart debug log once I perform “sys_reboot bootloader” and the Right side if image it fastboot command. The fastboot command never executed because fastboot could not catch any fastboot device.
It look like AG55xQ default firmware stuck in bootloader.
Highly appreciate for your support and feedback promptly.
