Hi ,

Currently, i am flashing binaries through blhost commands
Everything working fine but in write memory failed case i am unable to detect COMX in device Manager.
could you explain how to recover device and how to view COMX port active state in Device Manager.


currently, following below steps:
././bin/windows/bl host.bin -u -- get-property 1
././bin/windows/bl host.bin -u -- flash-erase-all-unsecure
././bin/windows/bl host.bin -u -- read-memory 0xb700 256
././bin/windows/bl host.bin -u -- flash-erase-region 0x0 0xb800
././bin/windows/bl host.bin -D -u -- write-memory 0x0 C:\tmp.bin
././bin/windows/bl host.bin -u -- reset


kindly provide a solution for this 


Thanks & Regards
