The kernel was builded with arm-eabi compiler...also EABI support is
tutned on:
[*] Use the ARM EABI to compile the kernel
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTAL)
Do you think, that it won't work with filesystem placed on not-yaffs2
partition??
I have mkyaffsimage tool for yaffs2 filesystem...but is it possible to
create image with erase block size = pagesize = 2KiB??
