Re: petalinux uboot data abort



I would suggest loading Linux Kernel Image ,device-tree & uramdisk through u-boot  to understand the actual problem.For petalinux you have to convert zImage to uImage.

u-boot> fatload mmc 0 0x3000000 uImage
u-boot> fatload mmc 0 0x2A00000 devicetree.dtb
u-boot> fatload mmc 0 0x2000000 uramdisk.image.gz
u-boot> bootm 0x3000000 0x2000000 0x2A00000



Refer to the similar issue discussed in the below thread.
