LPC810 DIP 8 code

Hi,

I'm doing some work with the LPC810 and can't seem to bring it to life! I am using this hello world program

Import programlpc810_helloworld

LPC810 LED blink test using LPC812(LPC800-MAX) online compiler.

Last commit 27 Aug 2014 by Norimasa Okamoto

and even though I think I have programmed the target the LED does not blink.

Any ideas anyone? Has anyone actually got this working using an mbed complied program?

Cheers Martin

I had the same problem. Could not get the example to run. Norimasa recommended to use SWI for flashing instead of bin2hex and flashmagic combination. I havent tried that yet, but dont see why that should be different. Note that you cant really use mbed libs with the LPC810. Lib size exceeds small flash of LPC810. Especially printf stuff is huge..

Personally I also don't understand how that assembly file would fix the issue of less RAM memory.

What you can try is import mbed-src, in it go here: http://mbed.org/users/mbed_official/code/mbed-src/file/b5886236e6f0/targets/cmsis/TARGET_NXP/TARGET_LPC81X, and put the files from TARGET_LPC810 into the TARGET_LPC812 folder. You probably can still make files that are too large, but it might work.

Hi Erik, I tried this, it complied but didn't run on the LPC810 :-( I'm surprised that we can't get this chip to work using mbed - I thought that it was close enough to the LPC812 (they have the same datasheet!) which seems to work OK???

Any more suggestions anyone?
