We using K22 series controller.
We are using DFU Demo software to upgrade device firmware.
It's working fine with WINDOW 8 after disabling digital signature.
Now, we upgraded to WINDOW 10. We are getting error "Unable to open COM port" while upgrading the device firmware.
Will any one help me to resolve this issue?
Hi,
as I know, so far the driver can only support 32/64bit win7 and win8. officially win10 is not supported yet.
Have a great day,
Zhang Jun
