  • 259ad3212e This is a bit silly and fun, using an msp430 board, and taking jtag over serial to debug programs on the raspberry pi. It is slow but it happens to work David Welch 2012-07-07 01:32:59 -04:00
  • 11e7b38f4b adding two examples that are somewhat position independent, wherever the GPU places this code it will work (so long as it is not too close to zero, and a 4 byte aligned address of course). David Welch 2012-07-06 02:36:01 -04:00
  • 1521436e4f adding MIT License. providing all output files in uart02 to help folks having issues getting this running on their boards. David Welch 2012-06-29 17:47:53 -04:00

  • b690368e86 normally I dont post binaries, but perhaps due to the gpu firmware files and perhaps due to toolchain or build differences not everyone is able to use these examples directly. I have posted a few blinker binaries with the elf file and disassembly (.list file in this case) so you can compare your build to my build to insure the start code is in the right place, etc. David Welch 2012-06-28 15:15:17 -04:00
