Thanks for the links! It looks like the stock 2.6.x kernel does not work |
| 41 |
fully with the EP93xx chips, right? |
| 42 |
|
| 43 |
Do you know anything about running the kernel out of NOR flash? I ask because |
| 44 |
NOR flash can execute out of inself, instead of having to copy the kernel to |
| 45 |
RAM and run from RAM. This makes boot times faster, but NOR flash does not |
| 46 |
support filing systems the way NAND flash does (think compact flash, |
| 47 |
usbsticks, etc..). |
