Failed firmware upgrade on ELS61-E2 | Thales IoT Developer Community
July 13, 2017 - 10:50am, 2639 views
I have recently attempted flashing the firmware on the connect shield. I have access to the extranet downloads and found els61-us_e_gwinswup_rev01.000_arn0001400 which is a self-contained firmware update utility.
The process appeared to be going normally but the utility reported having failed after a number of minutes.
The USB port is not enumerating but connecting via the TTL serial port it is outputting a continuous string of ^SYSLOADING every second or so and is unable to respond to any commands or the firmware update utility.
Could anyone suggest how to recover this module please?
