Failed to boot up with fsl-sdk-v2.0-1701 in LS1043ARDB

[szlin]

Hi all,

I got boot hang issue with fsl-sdk-v2.0-1701 in LS1043ARDB.

According to LS1043ARDB SDK 2.0 boot without using rootfs in the kernel.itb?  , I used following commands to boot up my 1043ARDB board.

The uImage, dtb file and rootfs are placed in SD card

setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootdelay=5 earlycon=uart8250,0x21c0500,115200"

fatload mmc 0 0xa0000000 uImage

fatload mmc 0 0x90000000 fsl-ls1043a-rdb.dtb

bootm 0xa0000000 - 0x90000000

I can boot up the system with branch "remotes/origin/sdk-v2.0.x-odp" by using above commands, but got boot hang issue with tag "fsl-sdk-v2.0-1701"

Kernel source: git://git.freescale.com/ppc/sdk/linux.git

Kernel config: The configuration files in arch/arm64/config (defconfig and freescale.config) are both failed to boot up.

Does anybody know the different between branch: sdk-v2.0x-odp and tag: fsl-sdk-v2.0-1701?

Should I modify my console device node or something?

Hi Yiping,

Since I don't use ramdisk, should I remove this item in its file? something like following setting

Header 1
/dts-v1/; / {         description = "Image file for the LS1043A Linux Kernel";         #address-cells = <1>;               images {                 kernel@1 {                         description = "ARM64 Linux kernel";                         data = /incbin/("./arch/arm64/boot/Image.gz");                         type = "kernel";                         arch = "arm64";                         os = "linux";                         compression = "gzip";                         load = <0x80080000>;                         entry = <0x80080000>;                 };                 fdt@1 {                         description = "Flattened Device Tree blob";                         data = /incbin/("./arch/arm64/boot/dts/freescale/fsl-ls1043a-rdb.dtb");                         type = "flat_dt";                         arch = "arm64";                         compression = "none";                         load = <0x90000000>;                 };                 ramdisk@1 {                         description = "LS1043 Ramdisk";                         data = /incbin/("./fsl-image-core-ls1043ardb.ext2.gz");                         type = "ramdisk";                         arch = "arm64";                         os = "linux";                         compression = "none";                 };         };         configurations {                 default = "config@1";                 config@1 {                         description = "Boot Linux kernel";                         kernel = "kernel@1";                         fdt = "fdt@1";                         ramdisk = "ramdisk@1";                 };         }; };

Hello sz lin,

No need to modify this configuration file, just use the default provided in Linux Kernel .

Thanks,

Yiping

[szlin]

Yiping,

Thanks for your reply.

I can see more booting messages by using your method; however, it still got hang issue.

[    0.000000] GIC CPU mask not found - kernel will fail to boot.
[    0.000000] GIC CPU mask not found - kernel will fail to boot.

I used default.config and freescale.config to make kernel .config, are these configs suitable for version fsl-sdk-v2.0-1701 ?

Hello sz lin,

Please also update u-boot to the latest, and please also deploy PPA image under u-boot.

Please refer to Linux SDK user manual for the addresses allocation.

Have a great day,
Yiping

Yiping,

Thank you for your great support, it works now after upgrading 4 files which SDK manual mentioned !

[tracysmith]

Please list the 4 files upgraded that the SDK manual mentions and the page number where they are mentioned?

Hello sz lin,

Please use the following method to boot from SD

=> ext2load mmc 0:2 a0000000 kernel.itb

=> setenv bootargs  "root=/dev/mmcblk0p2 rw earlycon=uart8250,0x21c0500 console=ttyS0,115200"

=> bootm a0000000:kernel@1 - a0000000:fdt@1

Have a great day,
Yiping
