Hi, I had a few questions about the GC Linux happenings... 1. How fast is the SD card access on the GC? 2. Are there any plans underway to just enable running Debian on the GC (non-NFS)? It would be nice to be able to simply boot the PowerPC netinst image with a minor amount of hacking, and just do a netinst onto and run off of SD, since flash is so cheap nowadays. Hence my question #1... Thanks! |

Hello again. I just started looking at the driver when the thought occurred to me... Would this driver speed things up? It was written to stick an MMC card on one of those Linksys routers. Yank out the bit twiddling of the GPIO port, stuff the EXI calls in their place? http://kiel.kool.dk:27/mmc.c On 7/10/05, Rob Reilink <ro...@re...> wrote: > GoatZilla wrote: >=20 > >Hi, I had a few questions about the GC Linux happenings... > > > > > >1.

Personally I think the best way is to use kernel/drivers/mmc/mmc.c. Write/adapt a host interface for that and perhaps patch it to accept SD as well. SD just needs a little different initialisation, code is in the existing sd card driver. Unfortunately, I won't have the time to do that, working about 24/7 on this: http://www.solarteamtwente.nl/ . This is a project which has a deadline end of august, and we need to get a lot done to get everything working on time :( Regards Rob GoatZilla wrote: >Hello again. > >I just started looking at the driver when the thought occurred to me... > >Would this driver speed things up?
