Baofeng DM-32 --> OpenDM-32

I'm trying to load firmware .bin file "OpenGD77_DM32_20260711.bin".  Just opening the .bin file in the OpenGD77 CPS cause the CPS to freeze.  The CPS is version E2026.7.13.01.

It is NOT the programming cable, because it happens even if the cable isn't plugged in.

EDIT: I tried the setup on a different PC, and it works fine.  So I'm guessing there's some sort of conflict somewhere.

Report this bug in the OpenGD77 forum, not here. They handle the CPS.

How is this firmware improved over the stock firmware?  Are there any added features not in the stock firmware?

I couldn't even program the DM-32 until after switching to this firmware because the factory/stock CPS and firmware were extremely buggy.

OpenGD77 was originally created for the Radioddity GD-77 but also ported to a few Baofeng handsets.  Some clubs in my area have produced codeplugs of all of the analog and DMR repeaters in the region, specifically using Open GD77 because of the simplicity and flexibility over other codeplugs.

You can reach out to Roger VK3KYY/VK2KYF by email.  He is one of the devs behind the original OpenGD77.

Roger's answer was to send me back to this website.  He apparently has nothing to do with the OpenDM32, which is the DM32 version of OpenGD77.

He is helping in the background, for example, creating an updated version of the CPS to support the radio.
I think that once the code base is more stable and a github can be set up, we'll be in better shape.
Actually, OpenGD77 has never been able to support certain DMR features like SMS-style messaging and such.  Maybe once this code is stable and can be put in a github, someone can even figure that one out.

Meanwhile, I'm grateful for what we have and what the volunteers here have done.  I can't imagine it is easy.

I agree.   I actually like this firmware compared to the stock DM-32 firmware. 

I've found two major issues:

The radio will occasionally freeze up; turning the radio off doesn't turn it off.  You have to pull the battery and re-start ,.
The radio does not send DPL codes on transmit (RX is okay).  So any local repeaters using DPL cannot be accessed.  CTCSS works fine.

I hope the developer reads this forum.  I would really like to see this new firmware continue to evolve. 

While the original developer is loosely involved, the majority of the work is being done by Koshak and Andynvkz.  Roger is the original OpenGD77 developer and has helped as well, but the DMR and reverse engineering stuff have largely been Koshak and Andy.

Thanks for the info!

Experimental versions of OpenDM32 firmware will be available on this forum. Unfortunately, the official OpenGD77 forum is archived. I'll let you know when there's news.
