Hello ModalAI team,
My VOXL 2 will not boot and remains in QDL mode even with SW2 in the OFF position. Could you advise whether there is an approved recovery/diagnostic procedure, or whether the board requires an RMA?
Confirmed details:
Chip marking: QRB5165M; recovery image: M0054(154)-1.zip.
Powered through a ModalAI power module.
SW2 checked with a multimeter: no continuity when OFF.
Ubuntu host; modal-qdl repository commit 136f4b7 (2026-03-06).
Repeated recovery attempts fail at the same point. USB connection and Sahara programmer transfer complete, and Firehose starts, but opening UFS LUN 0 fails.
The log reports:
Can't decode attribute slot with value
Failed to initialize (open whole lun) UFS Device slot 0 partition 0
Failed to open the device:3 slot:0 partition:0 error:0
Failed to open device, type:UFS, slot:0, lun:0 error:3
qdl: firehose operation timed out
[PROGRAM] failed to setup programming
Flash flat build failed
The web interface incorrectly displays a green success message despite these log errors. The full captured log is attached. It reports chip serial 456372656 (0x1b33b1b0); this is the programmer-reported chip identifier, not a confirmed board-label serial number.
Can this indicate recoverable UFS configuration/provisioning, or should the board be inspected for a storage/power fault? Please advise on the appropriate next diagnostic step or repair/RMA process.
Thank you,
