I'm not overly familiar with the prime architecture but I've done more than a bit getting code to run from flash (m68k no-mmu execute in place shared libraries which made it into gcc). From a post in another forum, the flash seems to be a NAND (K9F2G08U0C from Samsung), and therefore appears to the CPU as a block device connected to the NAND controller in the CPU, not as an actual memory bank connected to the Memory Controller. While there's usually a 4 kbyte window of SRAM that could be used to execute code without using the main RAM (as far as I know it's used only to bootstrap bootloaders), all you can do with NAND is read/write blocks like a disk device. |
