Comprei agora 01/23 um RT3S e tentei instalar o Open e a tela fica preta e nada acontece.. Não funcionou.. Voltei para a versão original. Alguem sabe o que fazer ? s/n comeca com 2212R......

Just read this thread. Use Google translate if you can't read English

one thing that bug me about all this is that i can load openrtx on it , and it will run it.. what is the missing part of code to have it supported by opengd77?
thx to everyone who is contributing to this endeavor

OpenRTX do not use the official STM hardware code libraries (HAL) or FreeRTOS etc

The code appears to be crashing somewhere inside either a HAL library or FreeRTOS

The original firmware seems to be unaffected by the MCU change, looked on Retevis site and the various images for 19.06 is dated 2022-03-14.

But I guess that the stock firmware is designed differently so that handles this clone ?

More like, it just happens to work.

The STM32 clones have various differences from the genuine chips, so sometimes firmware works, sometimes it doesnt

Just do a search on the STM32F103 clones / fakes and you'll find loads of information about where some firmware works on the clones and some does not
e.g the electronic timing of signals in these clones is often different from the genuine chips and if the firmware relies on accurate timing it may not work.

In this case I have no idea why Amazon FreeRTOS does not work with this chip.

I didn't write the OS.

heads up I got a RT3s GPS off ebay account retevis posted the day all the bad news came out (smells official they were very kind via ebay messages so adds to the official)

anyway serial 2208R03S11... (FCC:2AAR8RETEVISRT3S) flashed with no issues it appeared NIB ready for import like back in the day when you could get two for one deals on them.

the box has a sticker with A9110F on lower left (likely batch or programming code)

if that helps .. 73

Thanks for the information.

Hopefully people can still get hold of a few radios from the previous production batch

I'm waiting for a uv380 to arrive, I'll probably be changing the chip for an original one for testing, maybe it will work... if it works it will be a possibility to install OpenGD

Its quite a bit chip to replace, and you'll also need to reflash the bootloader onto the chip using something like a STLink or JLink
I have seen STM32F405 for sale on Al
I don't think I have posted the bootloader bin file, because no one has needed it, but I have the data for both the bootloader in my RT3S and also from VE3NCK (as I wrote an firmware application to dump the bootloader has hex and asked VK2NCK to run the the application)

Let me know if you need the bootloader

OK.

Hopefully you will receive a radio which works without modification
