When using the satellite function (for listening to traffic on the satellite) and then turning off the radio station, it cannot be turned on (or it works when I hold the button under the PTT while turning it on, the settings change, after restoring the settings from the backup everything works as i...

The question was "how to flash under Linux?" And what is included in this process is already particular. I have the following problem, when I try to enable PTT, "Error Rx Only" occurs UPD: It turned out that the codeplug flooded somehow strangely, the parameters are not correct everywhere (and ther...

Your post is confusing

Codeplug is not transferred via DFU, only firmware is transferred by a Custom DFU protocol on these radios
I will change the title of the topic

It is not possible to load firmware onto these radios using normal DFU tools Daniel F1RMB has written a Python based loader to support installing the firmware from a Linux computer https://opengd77.com/downloads/CPS/Latest/Linux_loader_for_STM32_radios Note. You still need to download an extract the...

FYI

I opened my MD2017 today and I will try to find all the pin connections to the STM32

Edit

It looks like the connections to the Flash chip are on the same pins as the UV380 etc
