Re: this week work on KBOOT

[xiangfu]

I am very sorry about my English. i should work hard on English. :-[ thanks for the suggestion.   "write a minimalistic NAND loader for GTA02 (using the relevant code   from u-boot as an inspiration)" It is my understanding that we just build a first-stage bootloader for kboot, use the mini loader to boot KBOOT or REAL SYSTEM. so this loader don't need command like in uboot. just to boot the KBOOT. :-) Best regard!

What we suggest is that Xiangfu continues the work towards kboot, namely: - write a minimalistic NAND loader for GTA02 (using the relevant code from u-boot as an inspiration) - move initialization that is currently in u-boot but that is not part of the minimalistic NAND loader into the kernel - as a proof of concept, boot a kernel image with a "hello world" initramfs I've described this with more context in my mail with the general work breakdown for making kboot happen, so I'd suggest to look there for details. If anything needs clarification or if Xiangfu hits some nasty problems, we won't bite his head off for asking ;-) Andy has pointed out that Xiangfu may have some difficulties getting things to build and run in the first place. For this, I'd suggest to replace u-boot with some simple program, e.g., one that just blinks a LED, and gradually build things up from there. As development platform, I suggest to use GTA02, since it has a u-boot in NOR, so it's easy to replace the NAND content during development. Regarding the dynamic partitions: Andy and I feel that it's better if we tackle these between ourselves. - Werner
