| |
Hello,
I am trying to boot 2.6.24 kernel on SH4 eb using embedded initramfs.
The kernel boots, but when trying to decompress the initramfs image it fails with "crc error", resulting from lib/inflate.c::gunzip:1250.
Has anyone got this error? The initramfs image is correct. I also dumped the memory of __initramfs_start->__initramfs_start and verified that it matches the initramfs image on usr/initramfs_data.cpio.gz.
I then noticed that the kernel code at init/initramfs::unpack_to_rootfs:459 supports handling uncompressed archives. So I compiled a kernel with uncompressed archived.
I also hooked the init/initramfs::do_name:585 functions, and see that "/init' is passed to sys_open, and sys_open returns with -EOENT (-2).
How can it be? shouldn't rootfs always be available?
The same attempt on i586, mipsel is working as expected.
Any ideas? 1. Why decompression working for kernel and not for initramfs (crc error). 2. Why files cannot be created on rootfs?
Thank you, Alon Bar-Lev.
