Problem upgrading firmware

[Javier Pedrido]

Hello,

I’m having a problem upgrading the firmware of one of my 915 Mhz mdots. The problem seems to be the same as https://www.multitech.net/developer/forums/topic/error-update_firmware-failed-to-back-up-current-firmware/

Upgrading via the bootloader fails with:

[INFO] Starting YMODEM file transfer
[ERROR] failed to receive ‘fw_upgrade.bin’
[ERROR] YMODEM file transfer failed
bootloader :>

Using micro devel board also fails to update it.

Should I erase the entire flash?

Thanks in advance,
Javier

If I try to do a soft reset I get:

[INFO] Backing up current firmware
[ERROR] backup_firmware: open failed
[ERROR] update_firmware: Failed to back up current firmware
