my cpu is BCM958522ER which is the same series with 4708 as well, 32MB spi-nor flash,

I want to know why this error arise, any hints will be appreciated.

My guess is that it's some problem caused by this board using U-Boot.
It's the first time I hear about someone trying Broadcom ARM, U-Boot
an OpenWrt.

I guess U-Boot doesn't like our kernel.
Our config uses CONFIG_KERNEL_XZ=y, but we also seem to be using lzma,
see target/linux/bcm53xx/image/Makefile.
You may want to check how original firmware (SDK, whatever) builds &
prepares the kernel.

Did uboot load all of the image into memory?
Where did it load the image?
Where will the kernel decompress to?
Is there room for it to be decompressed?

As the ram space is up to 256MB DDR3, thus there is sufficient memory to be decompressed kernel.

There is a breakthrough, the xxx.trx file is not ok while the zImage-xxx.lzma can work.

But still remains lots of work to be done.

the target platform *.dts file should be like this:

/dts-v1/;

#include "bcm4708.dtsi"

/ {
compatible = "via,vnt5903", "brcm,bcm4708";
model = "VIA Networking Technology 5903 (BCM4708)";

chosen {
bootargs = "console=ttyS0,115200 earlyprintk";
};

memory {
reg = <0x00000000 0x08000000
0x88000000 0x08000000>; /* 128MB + 128MB = 256MB */
};

chipcommonA {
uart0: ***@0300 {
status = "okay";
};

uart1: ***@0400 {
status = "okay";
};
};
};

below information is the log from zImage.xxxx.lzma:

I think next step is to add the flash support on my board,
below is my spi nor flash parameters, how can I make it work with squashfs filesystem ?


Model : N25Q256A
SIZE: totoally 32MB, (64KB sector size)
bus num : 0
gpio cs num : 0
internal interface with CPU


the bcm4708.dtsi and bcm5301x.dtsi did not show much information about spi-nor-flash.
