Error Downloading Firmware WP77xx mangOH Red

mangOH Red

Hi I’m following
https://mangoh.io/mangoh-red-resources-getting-started for the mangOH Red WP77XX.
I’m on step 7 - iv) in the guide (to download firmware onto the device). But I am met with this result while using swiflash:

swiflash -m WP77XX -i 9999999_9907618_SWI9X06Y_02.22.12.00_00_GENERIC_001.051_000.spk
Detecting USB of the target
DONE
Communicating with the target
DONE
Switching to firmware download mode
…ERROR: Failed to enter download mode

The device then becomes unresponsive and I have to power cycle it for it to enumerate again.

Anyone have any similar issues/ a fix?

If I encounter this, I try each of the following workarounds

  1. power cycle the mangOH
  2. run legato stop on the mangOH before running swiflash
  3. power cycle the PC running swiflash

tipically how mamy time requires this action?

It’s still downloading after 30 minutes…is it normal? it’s a combined file: modem.spk, legato.cwe and yocto.cwe
