Comment (by mchwalisz):
I have downloaded the patch series, applied, compiled and tested on TP-
Link WDR4300 router.
There are couple of comments. First if you load `openwrt-ar71xx-generic-
vmlinux-lzma.elf` it complains about being not in gzip format. It still
boots correctly.
{{{
# kexec -d --command-line="board=TL-WDR4300 console=ttyS0,115200" -l
openwrt.elf
`openwrt.elf' is not in gzip format:
kernel: 0x7753a008 kernel_size: 1409c9
kexec_load: entry = 0x60000 flags = 80000
nr_segments = 2
segment[0].buf = 0x41a11c
segment[0].bufsz = 100
segment[0].mem = (nil)
segment[0].memsz = 1000
segment[1].buf = 0x7754a008
segment[1].bufsz = 13082d
segment[1].mem = 0x60000
segment[1].memsz = 131000
}}}
I can also convert it to gzip and run successfully.
{{{
# gzip -c openwrt.elf > openwrt.elf.gz
# kexec -d --command-line="board=TL-WDR4300 console=ttyS0,115200" -l
openwrt.elf.gz
kernel: 0x77b43008 kernel_size: 1409c9
kexec_load: entry = 0x60000 flags = 80000
nr_segments = 2
segment[0].buf = 0x41a11c
segment[0].bufsz = 100
segment[0].mem = (nil)
segment[0].memsz = 1000
segment[1].buf = 0x77b53008
segment[1].bufsz = 13082d
segment[1].mem = 0x60000
segment[1].memsz = 131000
}}}
Still the command line has the part added by kernel (although I use
`--commnad-line` parameter, not append).
{{{
Kernel command line: board=TL-WDR4300 console=ttyS0,115200
rootfstype=squashfs,jffs2 noinitrd
}}}
It is still progress now I can boot correctly to the new kernel.
Previously console was misconfigured and hanged the system.
