Fake

Is mine a fake one? did I blow it up or does it miss some bootloader? In run mode the blink program runs.

Fake unlicensed Gigadevice and other clones exist

115200baud, 8E1 (even parity) ... Failed to detect F7 ... apparently the stm32 reads one byte to detect the baud speed.

USB D+ pin has 10kOhm insted of 1.5kOhm

boot0 set to 1 to enable programmer mode

boot1 set to 0 is system memory and set to 1 is embedded sram
