My port number is normally 71, so I don’t think this is related to the port number

Re: Code plug read/write error fixed?

Not sure what did it but I got a new blank cp to write to the radio. I used the cps new command to write with a fresh download of the open cps software (did I notice a recent update?) and it went the first time! I then downloaded the cp, modified it a bit and uploaded again with no problems.

Now wondering if I was using the “stock” cp modified by the open cps software to upload before??? :shock:

Potentially this could be a problem if the EEPROM does not respond fast enough and perhaps causes the USB to timeout.

Is this an old or a new radio ? There were issues with very old GD-77 radios, where we think they fitted cheaper / clone EEPROM chips which seem to be slower.

We also think this is the reason that the official firmware gets amnesia and doesnt remember which channel the radio was left on, as the official firmware probably doesn't bother to check whether the data has actually been written, especially when the radio is turned off.

New I assume, see image. The com port was 5 in the past but it did not even pause to ask or display.

Had the same write error as the first post on my Windows 10 Desktop, reloaded everything straight to a Windows 10 laptop and success first time--weird error, ports were low numbers??? No idea what the problem is but it is now working fine (on my laptop).

Lots of people are running it on W10 x64. The problem does not seem to be related to W10, either 32 or 64 bit.

Some people find they have to use a different USB port, so the problem is possibly in the driver that does not support some newer USB hardware.

I didn't write the driver. Its from a project called LibWDI

https://github.com/pbatard/libwdi

The installer I'm using was compiled ages ago by someone else, and I guess I should attempt to rebuild it, but its not top of my very long To Do list as it works for 99% of people

Thx for all your excellent work BTW and the comment----I kind of figured it was not likely to be just that difference of 32 to 64, so back to strange port choices!!
