p2020 doesn't boot from SDK 1.9

[alex16]

I have a custom board with schematics identical to p2020rdb. We used one with linux 2.6.30 SMP from 2013. Worked fine for us. I'd like to update one from NXP's Linux SDK 1.9, which has RTlinux 3.12. I download SDK, successfully build minimal image, tftp on the target but fail to boot. My u-boot listing is below. What did I miss? Do I need to update u-boot from my build as well? What commands could fix my problem?

Thanks Yiping for your writing tome. When I fail to boot my minimal image I found the prebuild image, you pointed to me, and I tried to boot from that. I used all components from the IMAGE ISO. Nothing had been used from my build. It fail with exactly same log as I provided. Looks like my build is identical to the prebuild IMAGE iso. Exactly same log. Have no idea what is the problem. I build kernel 2.6.35 minimal image for p2020 and that worked! I boot my board with linux 2.6.35. Looks like Konfig file made a good job for me. From NXP linux 3.12 I had build development tools. I cross compiled a HelloWorld app, copy executable on my target and that worked! So far, we can ship the board with linux 2.6.35 with development tools from 3.12 and customers could experiment on that by themself. I'd like to finish my linux 3.12 porting at mean time. Any idea how to go from working build 2.6.35 to port linux 3.12 build? I guess, 2.6.35 is not RTLinux, but 3.12 is RTLinux. Our customers will appreciate RTLinux options

Thanks,

Alex

Hello alex voytov,

According to the above log, u-boot has already passed control to Linux Kernel, Linux should be executed.

I suspect whether there is problem with your generated uImage with SDK 1.9.

Please download SDK 1.9 pre-built ISO "Image: QorIQ SDK V1.9 PPCE500V2 IMAGE" from https://www.nxp.com/support/developer-resources/run-time-software/linux-software-and-development-too... (previous version->previous). Please use uImage and dtb file provided in the pre-built image ISO to do verification in the current u-boot environment.

If this problem persists, please customize u-boot source in SDK 1.9 with the modification for your target board.

Have a great day,
TIC
