#19728: Bad Data CRC with 15.05-rc1 on a WNR2000v1
------------------------------------+----------------------------------
Reporter: nabcore | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos Calmer (trunk)
Component: base system | Version: Trunk
Keywords: WNR2000 15.05-rc1 AP81 |
------------------------------------+----------------------------------
Having flashed the current rc onto my WNR2000v1 (which is running 14.07),
I'm seeing this via serial:
{{{

The protocol used for this is was as follows:
1) Binaries were prepared using the image generator:
{{{
wget https://downloads.openwrt.org/chaos_calmer/15.05-rc1/ar71xx/generic
/OpenWrt-ImageBuilder-15.05-rc1-ar71xx-generic.Linux-x86_64.tar.bz2
tar xfvj OpenWrt-ImageBuilder-15.05-rc1-ar71xx-generic.Linux-
x86_64.tar.bz2
#Generate a leaner image
cd OpenWrt-ImageBuilder-15.05-rc1-ar71xx-generic.Linux-x86_64
make image PROFILE=AP81 PACKAGES=" -kmod-usb-core -kmod-usb2 -kmod-ppp
-kmod-pppoe -kmod-pppox -ppp -ppp-mod-pppoe"
}}}
2) Flashed as follows:
{{{
#On router running 14.07
cd /tmp
wget http://localwebserver/openwrt/15.05-rc1/openwrt-15.05-rc1-ar71xx-
generic-ap81-rootfs-squashfs.bin
wget http://localwebserver/openwrt/15.05-rc1/openwrt-15.05-rc1-ar71xx-
generic-uImage-lzma.bin
mtd -e rootfs write openwrt-15.05-rc1-ar71xx-generic-ap81-rootfs-
squashfs.bin rootfs
mtd -e uImage write openwrt-15.05-rc1-ar71xx-generic-uImage-lzma.bin
uImage
}}}
Note, prior to this, a modified u-boot bootloader (fuhry's) and mtd
partitioning scheme was in use:
{{{
cd /tmp
snarf http://fuhry.com/b/wnr2000/u-boot.bin
snarf http://fuhry.com/b/wnr2000/ubootenv-stockpartitions.img
mtd -e mtd0 write u-boot.bin mtd0
mtd -e mtd1 write ubootenv-stockpartitions.img mtd1
}}}
This had worked fine with 14.07.
