Little endian uImage booting LS1043ARDB problem

[刘刘波]

Hi, nowadays I have been working  debugging the LS1043ARDB, when I use the little endian toolchain of arm64 compile roootfs and kernel,   I start the board using tftp a0000000 uImage;tftp 90000000 fsl-ls1043a-rdb.dtb;bootm a0000000 - 90000000, but have some problem in the booting information :

Do you use NXP SDK for the LS1043aRDB board?

Usually u-boot from this SDK uses ITB file for Linux loading.

Have a great day,

No,  I use tftp a0000000 uImage;tftp 90000000 fsl-ls1043a-rdb.dtb;bootm a0000000 - 90000000 to start the 1043 board.

Hello Jianbo,

We suggest customers use SDK 2.0 downloaded from Linux® SDK for QorIQ Processors|NXP .

Would you please let me know why you don't want to use the Linux SDK provided by NXP.

Thanks,

Yiping

Because I need to change some function. The reason to the above problem I had found, which is caused by the lib extracted by toolchain, but I have not found the good method to solve it.

Hello Jianbo,

You could modify and rebuild Linux Kernel with the following procedure, then use the itb image directly.

You could modify Kernel source code or reconfigure Kernel, then rebuild images as the following.

1. $bitbake virtual/kernel -c cleansstate

2. $bitbake virtual/kernel -c configure

3. Go to the folder build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/linux-qoriq/4.1-r0/build/

Configure Linux Kernel with the command "make ARCH=arm64 menuconfig"

Modify Kernel source in "source" folder.

4. Rebuild Linux Kernel with "bitbake virtual/kernel  -c compile -f "

5. $bitbake fsl-image-kernelitb

Please do step 3-5 to continue modify and rebuild Linux Kernel.

Thanks,

Yiping

At first, thank you very much , but your method are not suit to me. The compile environment is not in SDK2.0, the kernel version is not linux-4.1.8. In other words, I have been debugging the higher kernel for LS1043ARDB to use, but I also thank you for your help.
