Hi,
The 2009 GSOC is winding down. I'd like to get some feedback on what people's plans are for USB support.
The GSOC experience demonstrated both some successes and challanges. I believe Jason was able to launch some executables with the code which demonstrates that it can work. However, there were some issues with memory management.
Besides the direct issue of not reserving the rom's memory, the memory needed is also an issue. The usbrom itself is just squeezing into 128K and it looks like it needs an additional 1M of working memory. In practice, I don't think the USB bootup code should use more than 30K of option rom space or more than 20K of reserved memory.
Anyway, it would be helpful to hear from those that are planning to work in this area and the work that they are planning.
Thanks, -Kevin
