Bluepill still blinks fast after burning roger's bootloader
Posted: Sat Jun 05, 2021 4:06 pm
Hey guys, I'm using a bluepill and I want to use Roger's bootloader because it's convenient. I am attempting to burn the bootloader to the bluepill thru FTDI but it can't connect to the bluepill, the error is "can't init...". When using st-link to upload my code, it blinks fast for about 2secs and then suddenly turning off instead of slowing down and then stop after 5sec or so. The connection to the st-link utility is stopped as well. Here is what I had:
- the bluepill from china. I used it to try some programs before with st-link.
- downloaded .bin file from Roger's Github
- I've checked the resistors on my board and they have right values.
- I have the FTDI from my friend and he has checked it so it should work properly.
Please let me know what I have done wrong.
Thanks in advance!
Edit: I figured out it is CS32F103 version because its CPUID is 0x2ba01477. Maybe it would be helpful to diagnose my case!
