I see someone mentioned bugs that are being worked out. Not encouraging. Is Gigidevice a company that makes FPGAs? Or am I mixing them up with someone else? Ah, I see I have downloaded their data sheets, so I guess I was looking at a low cost RISC-V board and also have info on their ARM ST clone chip. Wait, it's the same chip! No sign of FPGAs. That was one of the other companies like AGM, Anlogic or maybe Gowin. AGM has an interesting data sheet, but it's two years old and no sign of the device. > Seems to me that companies that box themselves into a corner over processors and second sources get what they deserve and is generally a sign of poor strategy and project management. I've worked on a couple of projects using essentially obsolete 8051 hardware, recommended a redesign using a more modern architecture, but they were not listening. Result was a greatly extended development time, costs, difficult ongoing software maintenance and compromises everywhere due to banked architecture for code and data. Having said that, have used the silabs 80F... series for a couple of small projects which worked really well. You wouldn't want to look at the asm op from the compiler, but more than adequate for the task and all written in C... Chris
