Flashing NuttX on STM32F429i-Disco board

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 '^]'.
