bricked mAP lite : SOLVED

Hi,

After upgrading to latest ROS version, my device is bricked. Eth and WiFi interfaces go up/down forever, so, no chance to establish connection. Tried factory reset and netinstall without success.

Besides RMA, is it possible to use a serial interface or JTAG to recover the device?

EDIT: Solved: Wireshark and a clean laptop installation were used to see whats is going on when the device boots. But I’d like to know if it is possible to use TTL/JTAG to recover this device

thanks,

regards,
m
