Hello,

I was able to program Micromod Sparkfun STM32 once , using arduino IDE , once I programmed Blink sketch, it does blink blue LED on STM32 , after that it does not show up as Seiral port in Arduino IDE, I do have USART enabled generic in tools menu, what I need to do so that I can program it again.

-Thanks

I am using procedure as mentioned to upload code(https://learn.sparkfun.com/tutorials/mi … e-overview) , but there is no serial port in Arduino ide so I cannot upload code, did boot loader on STM32 got overwritten, if yes How can I install boot loader again , and then How do I program so that it does not happen again…?

-Thanks
