Re: making blackmagic probe from stm32 chip board

R10 is the resistor marking on "most" bluepills. Unfortunately, there is no such thing as a "typical" bluepill. Each one is different. The R10 resistor is the pull up on the USB +DM pin on the bluepill I personally have and one one that is often talked about. However you didn't l...

Re: making blackmagic probe from stm32 chip board

on your bluepill board, have you checked the R10 pullup resistor to see if it is 1k5 ?

I honestly don't know. I can only guess.

It seems like you are using the board in a minority way not a majority way.

Re: Some pins not usable when using ST-Link ?

I don't see why the used board would be here relevant. But anyway, I am using alternatively Maple Mini clone or Blue Pill. I am using the pill alternatively with DFU (if I need 5V and USB serial) or STlink if I want to debug, very rarely. I ask because it would be very strange to use the SCLK and S...

Re: Some pins not usable when using ST-Link ?

...But i don't want to push my opinion, i obey the majority, i just hope that others will find this post and will know that they should use an Arduino non-compatible function "afio_cfg_debug_ports(AFIO_DEBUG_NONE);" in order to get their pin toggle in any simple sketch. I guess the previo...

Re: USBserial don't works - what's wrong?

... I can't use Arduino's compiler because this is not the only project on ARM :) The Arduino IDE installs the arm-none-eabi-gcc in the directory $HOME/.arduino15 (at least on linux). You can have the two coexist as the Arduino IDE uses a full path to its location, it won't conflict with other arm-...
