It's not entirely clear what you'd like me to try: mx28_dram_init
is called in U-Boot, while mx28_mem_init is SPL code.
I have tried to link SPL objects along, but I'm gett

I'm sorry for my late response; I was attending an FPGA workshop today. I will
test this first thing in the morning, when I'm at the office.

That's exactly where and why it hangs, in my case.

In my case, I don't think it hung in power_init before your patch. I'm pretty
sure it
hung at the same place
Hi,
Same here. I've applied the patch and tried it on my mx28evk and 'reboot' from
the
Kernel prompt results into DRAM: 0 Bytes and a hanging U-Boot.
I didn't try single-stepping with the debugger yet; I'm still messing around
with the PLL bypass bit and PLL configuration.
Cheers,
Robe

No. It works as before. Whatever that means :-)

Good, any improvements though?

I tested both patch on my mx28evk. At least I cannot notice any
missbehavior :-) Downloading the patched u-boot via USB recovery
download still does not work.
Marek, did you find any further mentionable difference between bootlets
code and current u-boot implementation?

The DC power STS shouldn't be checked if booting off 5V supply.
