SDRAM restrictions?

David Betz

Are there any restrictions as to which COG the SDRAM driver must run in like there is for video drivers needing to run in COG 0?

David, as far as I'm aware you can run the SDRAM driver on any cog, ( although I've mainly started it on the next one. COG 1 )

Thanks! Just wanted to make sure before I start playing with the SDRAM driver. My plan is to write a small program that starts the SDRAM driver, loads an image from flash, and then starts a slightly modified version of your WiredComputer program passing it the SDRAM parameter block. All I need to do with your program is remove the code that loads the SDRAM driver and instead just use the values passed in as parameters.

Excellent Can't wait to see it.
Will you be doing a version for P2Load?

Yes, I will load it with p2load. I can already write the image to flash using p2load and I can load and start individual drivers. Ideally, I'd like to load the SDRAM driver and the VGA driver separate from the WiredComputer program but I'm not sure I understand the VGA driver well enough to do that in the first pass.
