This is my openocd.cfg file:
# STM32F429i-Disco # Using stlink as SWD programmer source [find interface/stlink-v2.cfg] # SWD as transport transport select hla_swd # Use STM32F4x target set WORKAREASIZE 0x4000 source [find target/stm32f4x.cfg]
Just connect miniUSB cable to STM32F429i-Disco board and execute:
$ sudo openocd -f openocd.cfg
Now using telnet to connect on openocd server execute:
$ telnet 127.0.0.1 4444 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'.

The serial console is on the pins PA9 (connect to RXD) and PA10 (connect to TXD).
That is all!
$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg -c init -c “reset halt” -c “flash write_image erase nuttx.bin 0x08000000”
