EM9293 firmware upgrade problem

1

I used command ./fwdwl-litearm64le -d /dev/ttyUSB0 --modelfamily 3 -e 1 --fwpath “./” --dmreset to upgrade modem’s firmware, but it seems stuck at “BOOT and HOLD Mode. Downloading firmware …”, do I need to set something before upgrade modem’s FW ?

you should use the FW download tool in MBPL:

I use MBPL tool can upgrade modem’s FW successfully, but after upgrade FW, I use same way to download previous FW, it display “Device returned error message: Invalid image type”, so if modem has newer FW, can downgrade modem’s FW?

why did you need to download old firmware?

Are you able to download different PRI in FW 02.17.08.00?

Because we need to compare the performance difference between the new firmware(SWIX65C_02.17.08.00) and the old firmeare(SWIX65C_02.13.08.00)

no problem is found when downgrading from new firmware(SWIX65C_02.17.08.00) and the old firmeare(SWIX65C_02.13.08.00):
