Hello, I am troubleshooting a Starling 2 Max with an M0054-1 VOXL2 board that is currently stuck in fastboot mode.
Initially the board did not enumerate at all over USB (no adb, fastboot, or lsusb). I followed the unbricking procedure here: https://docs.modalai.com/voxl2-unbricking/#starlin-drones-with-m0054-2m0154-2
Using VOXL2 QDL Image 14.1a_1.7.8, the flash process hangs at the start and times out. Using VOXL2 QDL Image 14.1a_1.1.2, the flash completes successfully. After flashing 14.1a_1.1.2, I powered the board down and returned SW2 to the normal position.
After this, the board consistently enumerates as a fastboot device on power-up. I then followed the procedure here using the latest SDK: https://forum.modalai.com/topic/2789/voxl2-stuck-in-fastboot
The flashing process reaches completion and attempts to reboot, but hangs at the step that prompts a manual power cycle after approximately 60 seconds. After power cycling, the DS1 LED rapidly strobes red, but the startup tune still plays. Disconnecting USB-C returns DS1 to solid green and D1 to solid green. Reconnecting USB-C causes the device to enumerate again in fastboot mode and the cycle repeats. Disconnecting it after powering down and not plugging the device in until after a restart does not fix the issue.
I have tested multiple known-good USB-C cables. Additionally, the blue LEDs on the bottom of the Starling briefly strobe at power-up, then remain off for the rest of the uptime.
At this point, is there another recovery path I should try, or are these symptoms consistent with a hardware fault?
Thank you!
