Preloader uboot SPL

Hi, We have a custom Cyclone V board that runs vxWorks. All boot images are coming from the QSPI with preloader separated from uboot. Preloader starts @ 0x0 location, u-boot @ 0x60000. I'm not...

Hi,

I read through this thread. So I'm curious, what was the solution to the problem? I have a similar issue where I have a custom Arria 10 design and the Rocketboards instructions for building the bootloader don't seem to be working for me. The memory and IO do not seem to be getting configured correctly by the preloader. I get no output from the serial terminal while the preloader executes and I get the following error when uboot is loaded through the Arm Development Studio debugger:

+loadfile u-boot-socfpga/u-boot
Target Message: Memory access caused precise abort.
Debug Precise Abort Registers : DFSR = 0x00000808, DFAR = 0x01000040
ERROR(CMD16-TAD59-NAL18):

It seems like the qts-filter-a10.sh script used in the Rocketboards building bootloader instructions doesn't seem to be picking up all of the custom board configuration differences that need to get transferred into the uboot build files (like memory for example). I'm hoping that the solution to his problem will apply to my problem.

Thanks for your help,

Richard

Hi Richard,

Issue is still not resolved. Intel support suggested i re-open this when i come back from vacation, but i didn't.

I'm currently working with an ARROW tech support and a couple of Intel PSG to help me ]out.

Current status is that they suggest to debug uboot to see what's going on.

Good luck!
