Control Printer via UART

[dadwarf]

I managed to dump firmware using a ST-LINK v2 & OpenOCD or with STM32FLASH & USB to serial adapter.

Code:

Mainboard         ST-LINK

SWC9 / EN ------- SWCLK
GND ------------- GND
SWI7 / DIR ------ SWDIO
VCC / 3V3 ------- 3V3
B0 -------------- 3V3 (BOOT0 pull up)

openocd -f share/openocd/scripts/interface/stlink.cfg -f share/openocd/scripts/target/stm32f4x.cfg
telnet localhost 4444
dump_image dump.bin 0x08000000 0x00040000

OR ------------------------------------------------------------

Mainboard         USB to Serial adapter

GND ------------- GND
RX -------------- TX
TX -------------- RX
5V -------------- 5V
B0 -------------- 3V3 (BOOT0 pull up)

stm32flash -r dump.bin COMx

(not mine)

Now i have to disassemble it.. i don't know if i can post my dump ?
