Hi all,
I'm working on a Zynq-7000 system that currently performs a "legacy" boot - the kernel, device tree and initramfs are loaded independently into RAM, and then they're all loaded by passing their addresses into 'bootm'. I'd like to update this to a "moderm" boot, where the system loads a single FIT image instead. This is my first exposure to FIT images - I thought I figured out how to do this, but my system is crashing so I'm beginning to doubt myself ;)
This is the "legacy" load sequence (output omitted):
setenv bootargs "console=ttyPS0,115200 root=/dev/ram rw ramdisk_size=0x1600000 earlyprintk init=/sbin/init"
tftpboot 0x2000000 devicetree.dtb
tftpboot 0x2080000 uImage
tftpboot 0x4000000 initramfs.img
Here's the output when I actually boot:
Questions apart, I've tried latest u-boot and linux-next on Microzed
board and able to boot if you need please see below.
