First of all I want to thank Oliver for his great work and his selfless mindeset to share all his Products with the community.
I started some weeks ago to build my oen MI elements. Unfortunately i’m stucking at the moment, It doesen’t wrork
PCBs are from the original eaglefiles shared by Oliver. So I think thats not the problem. I checked all the relevant Voltages for the µC, and they are ok
What I can se so far, the crystal does not swing, this bring me tho my fist question.
- Should the crystal swing even without an unflashed controller?
I have the feeling that my firmware is not built in a correct way. For some reasons for me it its not possible to built the Bootloader SW-Version
So i create the normal Hexfile. I can flash this version without any issues over the STM32 ST-Link Utility Tool. But anyway after flashing the crystal doesn’t start. This brings me to my next questions.
- Is the Bootloader Version neccessary, or can I flash the only normal HexFile. (For my DIY Braids, it works in that way)
- If it is Ok to flash only the Hex file, can someone send make a binary compare with my Version any a 100% working one?
- If the Bootloader is neccessary, can someone built it for me?
Btw: for the right hint, there’s a little surprise
