OpenGD77

I installed DM-5R file.... what's the difference with the RD-5R .sgl? I am not able to change anything in the Options menus, like "Options", "Display Options", "Sound Options" 73! The DM-5R file got renamed to the RD-5R, to save confusion of users with the old DM-5R which was an completely differen...

There is already a discussion for this

Is the radio now running the OpenGD77 or the official firmware?

If its running the OpenGD77 firmware can you use the OpenGD77 CPS to backup the MCU ROM ?

Well Bangood my be serving me a different page, but look at the URL you posted and it contains the text STM32

Re: Firmware.

Does the radio currently boot up ?

I don't think there is a battery eliminator for the GD-77 or the DM-1801 which you can buy There is this design on thingiverse, https://www.thingiverse.com/thing:2742838 But I don't think my 3D printer could print it, because it has a lot of overhangs. I guess if you use a lot of support material it...

It will probably work even though the description says STM32 whereas the GD-77 uses the MK22 CPU

BTW. What firmware is currently in the radio. The official firmware ??

What did you buy ?

Which documentation ??

Yes.

Its not essential to have a debugger connected, but it does make development significantly easier and quicker.

Uploads via SWD take around 5 seconds, and being able to put breakpoints in the code and inspect variables etc is very handy.

If I merge this fix, I'd get complains from anyone using CTCSS on FM if it adds a squelch noise at the end of each over. Any fix should not introduce new problems. Well Colin fix or something else broke the rx ctcss, it is not usable anymore. our repeater needs rx ctcss (it is hybrid FM/DMR) Do you...
