The pwr led is controlled by uboot, different uboots have different settings
If there is something wrong with uboot you won't get the various xxxx bytes read statements
After kernel, initrd and dtb is loaded, uboot is done (assuming correct load addresses)
For further serial comms, you have to change console= statements in boot.txt and recompile(->boot.scr)
Maybe the video mis-config are in the dtb, or could be in kernel config
