Booting from the SD card

Testing the VGA framebuffer

Testing the preset loader and the shader

At the top, you see the list of the files present on the SD card. Then, a compiled preset is loaded ; all it does is compute the sum of 1.2 (0x3f99999a) and 0.2 (0x3e4ccccd) and store it in the "wave_r" variable, which has been affected address 2 in the shader memory. You can see the constant values preloaded into the shader memory (mapped at address 0xf0011000). Then the shader is run, and the result 1.4 (0x3fb33333) appears at address 2 !
