Usage

Once OpenOCD is running, you must connect to it using telnet on port 4444. This will give you a command prompt, where you can issue the following commands.

Note: When flashing an image, use the 5v power supply, as USB cannot provide enough current
halt halt...
reset reset...
reset halt reset, and immediately... halt?
resume [address] resume... (from address)
flash write_image erase <image> <address> put <image> into flash at <address>
load_image <image> <address> [bin|ihex|elf|s19] put <image> into SRAM at <address>
exit exit...

Loading

reset halt
load_image <image> <address> bin
resume <address>

Flashing

You must halt, flash and reset

Errors

flash failed

auto erase enabled
lm3s.cpu -- clearing lockup after double fault
error -302 executing stellaris flash write algorithm
flash writing failed with CRIS: 0x0
error writing to flash at address 0x00000000 at offset 0x00000000
in procedure 'flash'

This can occur due to under-current (powered by USB). Either try again, or power using a 5v supply.
