Issues updating Carrier Firmware on EM9191 and EM9291

IoT Modules MC/EM Series
1

Hello,

Having some issues with getting carrier firmware to update. Ideally I would like to load multiple carriers’ firmware onto my device which is soldered on a board with the imx8qm module. Please see below what occurs when I try to run a firmware update command. I also was getting the following error after downloading appeared to be successful “error: error downloading image: couldn’t teardown download: unexpected firehose response received: value=NAK, rawmode=false”.

how about using the FW download tool MBPL_SDK_R35_ENG4-fwdwl.bin.tar here?

This is exactly what I needed, the command worked once I modified it for my files. Thank you!
