My led is PB12 about u2f-token HOT 10 CLOSED

If you compiling with TARGET=BLUE_PILL, then try to change these two lines: https://github.com/gl-sergei/chopstx/blob/984116b3b64b93f5a9e315f8a805db74f22fb90b/board/board-blue-pill.h#L12

Ideally, you should prepare header file for your board and add makefile target.

BTW, which board are you trying to run it on?

from u2f-token.

I happened to have this board. Just tested it, it works with these changes:

Make sure to run

make clean distclean && make TARGET=BLUE_PILL

after applying the patch.

Please also note that since your board does not have a push button to check for user presence, firmware will allow register/authenticate only within 10 seconds after device has been plugged in. You'll probably need to unplug the device and plug it back (or press HW reset button) to authenticate.

I work witch stm32f103c6 and led pin is PB12. I for a long time could not understand why the standard example blink does not work and having looked closely to the board I saw that the LED is connected to the foot of pb12

from u2f-token.

The LED should do some kind of work?

from u2f-token.

For PB12 it should look like

#define GPIO_LED_BASE   GPIOB_BASE
#define GPIO_LED_CLEAR_TO_EMIT          12

and probably this line needs to be changed to something like

#define VAL_GPIO_LED_CRH            0x88838888      /* PB15...PB8 */

LED will blink when you plug the board and it will blink each time board communicates via USB.

i changed, but led didn't work((
maybe need change all lines?
#define VAL_GPIO_LED_ODR 0xFFFFFFFF
#define VAL_GPIO_LED_CRL 0x88888888 /* PC7...PC0 */

Nice its work! pls add it to compiler (Target=DARK_PILL)

from u2f-token.

The last question: where do I connect the button for authorization?

from u2f-token.

First, you will need to solder a push button. Then, you will need to modify pbt.c to read events on this button's GPIO PIN and probably board-blue-pill.h as well, to initialise that GPIO PIN.

For new makefile target I created #10
