[Yaffs-archive] Re: PPCboot et Yaffs

[Charles Manning]

It is not clear to me what you are trying to achieve within PPCBOOT
* Do you want to just use the bootloader?
* Do you want the whole file system?

YAFFS uses __KERNEL__ to distinguish between Linux builds and other builds 
(WinCE, etc). If you are using YAFFS in a bootloader configuration (ie only 
using YAFFS headers), then defining __KERNEL__ will want to include 
semaphores etc which Linux understands but a bootloader likely won't.


I suggest fiddling with the headers until you get a good compile (eg. 
substitute any __KERNEL__ in YAFFS with CONFIG_YAFFS_LINUX_KERNEL).
then come back to be with any suggestions for improvement.
