CAL DATA ERROR (Dumb Rooky Mistake) - Please Help!
Posted: Mon Apr 15, 2024 10:57 pm
G'Day,
I have a issue where I have a CAL DATA ERROR after installing OpenGD77 on a GD77 radio.
I think this was a result of me initially loading the incorrect version of OpenGD77, I load the version for the DM1801.
After I loaded the DM1801 firmware I backed up the the EEPROM, MCU ROM and Flash.
Once I found I loaded the incorrect firmware I then installed the correct firmware for the GD77, and it appeared fine on boot, it showed the OpenGD77 screen, that was as far as I got no testing at all, no code plug installed.
Next (rooky mistake ) thinking I knew what I was doing and thinking I was reverting to the original EEPROM, MCU ROM and Flash. I Restored the EEPROM that I had previously backed up, I also resorted the Flash, and then I got the error CAL DATA ERROR. Not sure if this was after the EEPROM restore or the Flash restore, however, I am now stuck. ( Note to self, Don't do stuff you're not sure of)
I have read elsewhere in the Forum that this may be a result of an damaged CAL header, but I am not sure how to fix it.
I do have another GD77 that is still on the factory firmware.
Can anyone please offer a solution..... I am thinking that I may be able to backup the EEPROM and Flash from the other GD77 with the factory firmware and then load that on the broken GD77 and then flash the factory firmware to the damaged radio..... Will that work ????
BTW feeling like a idiot about now.....
Any help very welcome.
