I was looking to interface FatFS to the MSP430G2744:
It has 1KB of ram (may be enough? If not I might look into using the MSP430G2755 with 4KB of ram)
I've been hacking away at getting it interfaced after doing Petit FatFS and realizing I needed to have resizable files and file creation (oops).... and that Petit has already been ported (double oops).
I've been able to get it to compile with GCC, here's the FatFS branch of the project.
But things are not running smoothly anymore, after I upload the code the LEDs are dim and it doesn't seem to execute past my little serial logging solution (in com.c)
I've taken a break for about a week and just started looking back into this, I'm feeling sort of lost at the moment, I'm not very good at low level debugging with the open source tools.
Thanks for any ideas,
Chris
