EM 9191 fireware download failed

IoT Modules MC/EM Series

I download SWIX55C_03.10.07.00-001_GENERIC_030.062_000.zip from the official website and unzip two files into folder Images:

 $ls ./Images
SWIX55C_03.10.07.00-001.cwe  SWIX55C_03.10.07.00-001_GENERIC_030.062_000.nvu

Then I run the command and fail at the end.

Do I use the wrong command or something?

Thanks!

Does it work in windows?
Have you installed the mbpl usb driver?

Yes, I install MBPL usb driver

❯ lsusb -t

Good to verify in Windows first.

BTW, in the past, I used the following and it was working fine for me:

We are using FTD in windows and the FW downloading works!

I had the same problem. I needed to update the linux kernel drivers to the latest package in order to make it work.

according to the user guide of MBPL, it supports open source kernel versions 4.4 and newer
