Hi Simon, I didn't look the code, but openFPGALoader is implemented in C++ and I don't know if they are using features that don't fit well to microcontrollers.
So, the only way to confirming if it works is trying to compile and run it. If you only need to use FPGAs from Lattice, maybe you can try to SPI iceboot approach: https://github.com/al177/blinkencard/blob/master/micropython/iceboot.py (disclaimer: I don't know much about FPGAs yet) BR, Alan On 7/13/23, Simon Filgis <si...@ingenieurbuero-filgis.de> wrote: > Sorry, I have a typo in the subject. > > Not FLASHLoader but FPGALoader. > > https://github.com/trabucayre/openFPGALoader > > The Segger Flashloader has been used by me already.
