[edit] 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... |
[edit] Loading
reset halt load_image <image> <address> bin resume <address>
[edit] Flashing
You must halt, flash and reset
[edit] Errors
[edit] 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.
