[Macchiato] MacchiatoBin GPU progress [#freetimeproject]

Fri Jun 9 11:32:02 BST 2017

Hey Ard

I am unable to try without the riser power, as the riser does not draw any power from the PCIe slot.  I would have to get a different riser to try this.

I will run some more boot cycles this evening with a nice glass of wine to keep me company and let you guys know what the results are.

/Matt

Ok, installed the newer bootloader (with the updated mv_ddr) as per the instructions below.

Things are looking a lot better, although this could be because of the small sample size I have taken.

On a run of 10 boots, 9 success and 1 failure.  A snippet of the failure is:

So it looks like it is still a pcie issue.  But a step in the right direction?

Absolutely, although statistically, I don't think we can draw any conclusions here.

I will run more boot tests when I have the time, but is there anything else you think I should try?

Please retry with the riser power disconnected.

And is it possible for me to install firmware that will solve the BAR issues?

Marcin? Any plans on the part of Marvell to fix this?

So Ard, are you able to outline the process I need to undertake to update ATF and the bootloader?

Congratulations. You have managed to find a working micro-SD card on
the first try :-)
