Linux simple image not working on P1022 custom board

santoshkumaraki · ‎04-28-2016

HI,

we are using p1022 processor based custom board.

we are able to download u-boot elf image to DDR using code warrior USB TAP and u-boot is running successfully.

we have extracted kernel source and cross compiler from sdk1.9.

while building Linux simpleImage we are receiving simpleboot.o file not found error.we have edited Makefile in arch/powepc/boot in order to generate simpleboot.o file .

After editing Makefile we are able to build Linux simpleImage for p1022ds.(device tree: p1022ds_32b.dts).

Loaded simpleImage.initrd.p1022ds_32b.elf file to DDR through code warrior in debug mode and observed program counter is getting halt at fdt_getprop routine in simpleboot.c file where fatal error "Cannot find #address-cells property" is occurring.

Can anyone tell me whether simpleimage will work for QorIQ processors or not.

As flash and Ethernet interfaces are not up in our board we are going for Linux simpleImage option.

Regards,

Santosh Kumar.

U-Boot's ELF loader is not intended for booting a device-tree-aware OS such as Linux, and the dts files for our chips are not intended to be used without U-boot fixups. Build a uImage and use bootm instead.

hi PavelChubakov and scottwood....

Thanks for your replay...

we have tried booting linux with SD card.After following procedure to boot from SD card, U-boot is coming up properly.

We have used default uimage and dtb file from SDK 1.9.

After using following commands in u-boot:

setenv sdboot "setenv bootargs root=/dev/mmcblk0p2 rw rootfstype=ext2 rootdelay=5 console=ttyS0,115200;mmcinfo; fatload mmc 0:1 30000000 /uImage; fatload mmc 0:1 3e000000 /p1022ds.dtb; bootm 30000000 - 3e000000"
run sdboot

Console prints are coming up to compressing kernel image.... and getting stuck(OK print is not coming).

By using debug prints in u-boot we have observed u-boot is getting stuck at inflate routine in lib/gunzip.c file.

can you please tell me where the issue is.....

Console prints are as follows:

We did not test similar loading.

It looks like that DTB file miss if halt happens at fdt_getprop. Usually our Linux SDK generates three files: kernel, .dtb file and rootfs.

We recommend using Flash, or SD card or Ethernet connection for image loading.

Have a great day,
