How to convert a BIN file to a UF2 file

[hejiayv]

I would like to ask how to convert my compiled bin file into a uf2 file

[pfeerick]

While it probably is technically possible, why? STM32F2 and STM32F4 radios do not use or understand them, only STM32H7 radios, and when you compile for them, you should be getting a UF2 file.

Can you help me answer this? I'll follow the instructions https://github.com/EdgeTX/edgetx/wiki/Building-radio-firmware-in-a-web-browser-with-GitHub-CodeSpaces How can I obtain firmware in uf2 file format when the compiled firmware obtains bin type files? My remote control is tx15

Are you using the correct PCB type / flags for your radio?

i.e. for the TX15 instead of of

cmake -Wno-dev -DPCB=X10 -DPCBREV=TX16S -DBLUETOOTH=YES -DCMAKE_BUILD_TYPE=Release ../

you should be using

cmake -Wno-dev -DPCB=TX15 -DCMAKE_BUILD_TYPE=Release ../

From start to finish that would be:

mkdir -p build && cd build
cmake -Wno-dev -DPCB=TX15 -DCMAKE_BUILD_TYPE=Release ../
cmake --build . --target arm-none-eabi-configure --parallel 2
cmake --build arm-none-eabi --target firmware

(note: if you ran a cmake command like the one for the TX16S in the build directory and now want to build for a different transmitter type, empty the build directory and start again. i.e. run rm -R * from within the build directory and then run the three cmake commands again. Failure to do so may resuilt in ... strange firmware generation).

If you then do

cd arm-none-eabi
ls

You should see both the bin AND the uf2 firmware.

Thanks for your reply.
