I have this issue:
PB3 and PB 4 should be a GPIO in push/pull.
For PB4 the remap and configuration works fine, but i cant get a high level out of PB3.
Here is my code:
RCC->APB2ENR |=1; /* Enable AFIO clock */ //disable JTAG ->
AFIO->MAPR |= (1<<26); // disable jtag & sw
// set GPIOBL
GPIOB->CRL = 0x333AA333; // set PB3 and PB4 to alternate push pull
Is something missing / wrong?
