the parts i ordered arrived
1. I replaced the 25 MHZ crystal no change B1 still shows same <see picture few posts back.>
2. replaced the Ethernet controller chip B1 still the same
3. replaced the 16 MHZ and of course <Murphy’s law damaged the board > however managed to tweak it and have it working there is no difference.
the device is detected through the USB connection and i can attempt to upload the firmware it turns the unit off starts to run and then fails
I have used 2 different PC’s to try and update the firmware on win 7 64 bit using the USB driver from the website CH341ser.exe (see below for error)
