i am reading the external analog pins PA1 to PA7, but only if i fake it as TQFP 100 or above, not QFN48. However, they should be the same chip inside. Also, it would not allow USB and full duplex USART1, so TX only.

They just need to make sure the micro is running, and call me if it's blinking red or not blinking at all. Normally, it should be blinking green.

It also complaints about many conflicts when enabling I/O pins, for which I know that they are not true.
