Hi,
I'm fairly new to embedded Linux so please take it easy on me ;)
I am using an ARM9 in an embedded system, and preferably want to boot Linux on it from an SD Card. Is this possible?
The ARM9 has 16 kB internal ROM. I can put a boot loader in there, which jumps to NAND flash . In the NAND flash I would like to put reboot or u-boot. When these are executed, I would like them to take a kernel image from an SD card.
Is this feasible? How much work would have to be done to redboot/u-boot for this architecture to work? If it's too much, I'll explore other avenues.
Right now I plan to have lots of SD Card space (maybe 1 GB), but not much NAND (is 1 MB enough for eCos+loader?)
Also, what advantages to redboot and u-boot have over each other?
I'm sorry if I'm asking very broad questions, but any help is greatly appreciated.
TIA, Pete
