hello, I encountered a problem during booting linux,.as attached picture, the process get stuck after loading dtb. I think it should be starting kernel next, but I don't know why it get stuck. My u-boot is working well, so I guess the problem lies in dtb.Attachment includes my dts for my board, could anyone check it for me or correct it to run linux well? my board parameter is :

cpu:P1023

norflash: 64M

DDR3L:256M.

nothing more!

the patition info is displayed in dts.if someone could give me a minimum system dts just for booting kernel, I will be apraciated

any one could help me?

We offer ready-to-use Linux "board support packages" for our processors.
For P1023 processor - this processor is supported by "Linux SDK for QorIQ processors":

http://www.nxp.com/products/microcontrollers-and-processors/more-processors/application-specific-mcus-mpus/c29x-family-of-crypto-coprocessors/linux-sdk-for-qoriq-processors:SDKLINUX

Note P1023 is mature product and may be not supported in most recent version of SDK.
Please look previous releases.

For example, SDK version 1.9 - file "QorIQ SDK V1.9 PPCE500V2 IMAGE.iso" contains ready-to-use binaries for P1023-based "RDB" board (folder "p1023rdb").

If your custom board is very far from RDB, than please build binary for your custom board from SDK sources.

Have a great day,
Alexander

SDK version 1.2 is very old and it is really painful for our support team to support old releases, you should understand that any suggestions can be given only for most recent SDKs which we use every day.

Regarding your board - you said your board is very far from RDB, please specify full list of differences.

hello, I want to know which version SDK should I use to develop P1023. On other

hand , I used SDK1.2 and made a little progress, but still have problem.See

attached, I think maybe I am very closed to success. Could you please to give

me a hand? All binary are generated by SDK , but still can't mount rootfs. I do

configurate kernel to support jffs2 £¬ and MTD. I really don't know why.Anyway,

if you can't gine me any advice given that SDK1.2 is too old, I will download

the SDK you recommend ! thank you !
