openocd lpc1788.cfg file
« on: October 16, 2012, 04:49:48 PM »
Where can i find lpc1788.cfg for openocd?
Mod-LCD 4.3" used lpc1788 mcu and on pdf manual in section 2.2 says
"
2.2 Requirements
...........
You may use any of Olimex’s ARM-JTAG programmer/debugger (For example ARM-USB-TINYH)
for this task.

Hello,

We have a lpc1788.cfg file up on the website, which uses the standard lpc17xx.cfg file in openocd.

You can find the files here:
https://www.olimex.com/Products/Modules/LCD/MOD-LCD4.3''/resources/LPC1788cfg.zip

Navigate to:
<openocd installation folder>/scripts/target/

and paste the lpc1788.cfg file from there. You'll notice that a file named lpc17xx.cfg is already present and all other specific lpc scripts call it at the end (the specific scripts are used to define things like RAM and ROM size, CPU frequency etc.)

Best Regards,
Maria/OLIMEX
