Hi. I think if U-Boot work memory make broken then Uncompressing Kernel Image is NG. Some ARM U-Boot is use top address in work memory. If this case your kernel start address to move to after work memory. But I never see in MIPS. And What is set FDT_DTS_FILE in your kernel configuration ? ----- Original Message ----- > From: Mike Wolman <mike@wolman.co.uk> > To: freebsd-mips@freebsd.org > Cc: > Date: 2017/5/9, Tue 07:48 > Subject: Re: onion omega2+ > > > More info in case anyone can point me in the right direction. > > I have found: > > https://forum.openwrt.org/viewtopic.php?id=53865 > > I have tried changing how lzma compresses the kernel by adding -d20 to > the build scripts eg: > > /usr/local/bin/lzma e > /home/mike/omega2/src/../root/mipsel_ap/boot/kernel.MT7628_FDT/kernel \ > /home/mike/omega2/src/../tftpboot/kernel.MT7628_FDT.lzma -d20 > > This did not work. > > > Looking at the onion omega conf I see that it uses mkuzip and not lzma > with the following settings: > > X_FSIMAGE_CMD="mkuzip" > X_FSIMAGE_ARGS="-L -d -s 65536 -v" > X_FSIMAGE_SUFFIX=".ulzma" > > So tried the following: > > mkuzip -L -d -s 65536 -v -o kernel.MT7628_FDT.ulzma kernel.MT7628_FDT > > mkimage -A mips -O linux -T kernel -C lzma \ > -a 0x80001000 -e 0x80001100 \ > -n "FreeBSD" -d kernel.MT7628_FDT.lzma > kernel.MT7628_FDT.ulzma.uImage > > > But this did not work either. > > > > On 08/05/2017 19:41, Aleksandr Rybalko wrote: >> Hi Mike! >> >> I see you have no "OK" after "Uncompressing Kernel Image > ...", so >> first point uboot decompressor fail. >> Why fail?
