EM7421 stuck in QDLoader mode

Hi,

How do I solve this status?

see if you can recover the module by re-downloading FW to it:

jordan@jordan-X240:~/QMI/MBPL/MBPL_SDK_R28_ENG5-fwdwl.bin/SampleApps/lite-fw-download$ sudo ./bin/fwdwl-litehostx86_64 -c QMI -m 4 -d /dev/ttyUSB0 -f /home/jordan/Downloads/FW_EM74x1/SWI9X50C_01.14.03.00_GENERIC_002.036_010/

Or you can try this in Windows :

fdt2.exe -f SWI9X50C_01.14.03.00.cwe SWI9X50C_01.14.03.00_GENERIC_002.036_010.nvu

Hi @jyijyi ,

Thanks for your help.

I use fdt command to recovey the FW.
I can into at port to setup module and I found that “imperf” mismatch, so I upgrade FW again and that can become to normal.
