but i dont have any -p flag /dev/cdc-wdm0
ls: cannot access ‘/dev/cdc-wdm*’: No such file or directory
how about doing the fw upgrade command without -p flag
fwdwl-litearm -d /dev/ttyUSB0 -t 1 --fwpath “./” --cwe SWI9X50C_01.14.02.00.cwe --nvu SWI9X50C_01.14.02.00_GENERIC_002.035_000.nvu
bash: fwdwl-litearm: command not found
did you download the SDK?
e.g.
\MBPL_SDK_R20_ENG4-lite.bin.tar\MBPL_SDK_R20_ENG4-lite.bin\SampleApps\lite-fw-download\bin
yes download the MBPL_SDK_R20_ENG4
then you should be able to run ./fwdwl-litearm
