Cortex-M55

Fake

Is my bluepill 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

The ST-Link/V2 is based on a STM32F103C8 it has an ERNI 4-pin SWIM connector and a 20 pin flat ribbon for JTAG/SWD serial wire debugging

JTAG: TCK, TMS, TDI, TDO

SWD: VCC, GND, RESET, SWCLK, SWDIO, SWO

For STM8, use the SWIM single wire interface module

For STM32, use the 20-pin interface. Connect the SWD pins VPP, GND, CLK, DIO
