解决方法：

1. petalinux-config/uboot - netstart offset change from hex 0x1000000 to desired value - my image.ub ~20M, but I set it to 0x4000000.

2. In your petalinux project config files for u-boot 'platform-auto.h' change CONFIG_SYS_BOOTM_LEN from 0x1000000 to same value 0x4000000.

 

rebuild the whole thing.

 

During u-boot start stop it and verify your u-boot settings  loadaddr and netstart set to 0x4000000. If not - change them and save: "set loadaddr 0x4000000",..., "saveenv" and reboot.
