Well, I know it’s been a while since I mentioned QiX, and we’ve gone through a lot of changes.
We’ve settled on an ARM 9 based CPU (i.MX233) and a DSP56720 (dual core 400MIPS) as starting points. Both of these are available in QFP formats, so the cost of prototyping is low (which is always a good thing).
To this end, I’ve got one of the i.MX233 development board, and getting Linux up and running was a no brainer, it came with it. Hooked up a screen typed a few command lines and bingo, pictures below. What this does mean is that Freescale have a BSP for it, so a large portion of the work is already done. It will also boot from SD card, so that’s my next step, building a Linux kernel on SD.
I intend to get this talking to the SoundBite board I also have from Freescale, so I can get a pretty powerful DSP development system.
