Read/Write Error

Post by KF0EJV » Sun Aug 22, 2021 2:08 pm

Cannot read or write to radio. Get a "communication error" message when I try do either one. Have been through the firmware flash procedure several times, used the July and May updates, downloaded the drivrs several times, tried writing a blank codeplug, nothing is working. Suggestions extremely appreciated!

Don't think my drivers are loading. Screen says drivers extracted but the drivers loading screen just blinks and times out. Computer info:

- Windows 10 Home
- Version 20H2
- OS Build 19042.1165

Saw some previous similar posts but all had links to GitHub files that I cant access. Suggestions much appreciated!

Just reloaded everything on a different PC with Windows 7. Was able to download the new firmware with no problem but STILL will not read or write to radio. Still get the same error message: "communication error". Truly out of options, Please help.

Hi,
  • does your GD is running in normal mode ?
  • do you see the OpenGD77 serial USB device in Window's device manager ?
  • are you running the latest OpenGD77 CPS (just to be sure)

Cheers.
