apritzel: No, I'm not sure. It's hard to say what these pins are. But it seems like they're not connected to the pins in the microSD connector

Oh, I didn't notice that I was trying to use a regular image instead of toc0
radxanaoki has joined #linux-sunxi
<junari>
yep, it was the wrong image format, now uart output isworking
<junari>
sunxi-fel does not work with toc0?

apritzel: well the suniv dram code is directly taken by me from project
<MoeIcenowy>
just translated to be usable on u-boot
<MoeIcenowy>
from xboot project *
<MoeIcenowy>
why did I missed xboot here ...

junari: no, sunxi-fel at the moment requires an eGON packed image
<apritzel>
junari: technically it's independent on what the BROM expects, since sunxi-fel "unpacks" any given image and uploads the components separately
<apritzel>
and I have some patches to teach sunxi-fel how to unpack a TOC0 image and use that instead of eGON, but there is some bug in there somewhere, and I gave up debugging at some point :-(

apritzel: how do you think I can get a register dump?
apritzel_ has quit [Quit: Leaving]
apritzel has joined #linux-sunxi
<apritzel>
junari: register dump of what, exactly?
<junari>
DRAM PHY and CTL
<apritzel>
of the P85T tablet? I think the DRAM parameters should be in the boot0 binary, try to decode that with sunxi-fw
<apritzel>
you said yours is LPDDR3?
<junari>
Yes
<junari>
I extracted dram_para from DT, know i want to look to register dump
<junari>

I'll probably try to build later some kind of a vendor bootloader but with u-boot console

junari: ah, I missed that we don't support LPDDR3 yet ...
<apritzel>
junari: what is the DRAM clock frequency used by the BSP?
<junari>
792 MHz
<apritzel>
uuh, so it's probably LPDDR3E then, at 2133 MT/s, as I see 672MHz and 792 MHz in the parameters list, and given the usual underclocking ...
<junari>
The DRAM chip is labeled as skhynix h9cknnncptmr
ftg has joined #linux-sunxi
<jakllsch>
Gesundheit
<apritzel>
so it's LPDDR3-1866, still underclocked, of course
