montjoie: i also haven't found anything better than the "press release", and that after experimenting with the h6 / a64 i'm not expecting anything too "good" / "interesting" tbh
<montjoie>
for my interest, crypto hw, they are never good
<apritzel>
are there any kind of technical docs (user manual?) for the D1 at all?
<apritzel>
(I guess crypto support is the least of our concerns ...)

apritzel: in the best case allwinner will recycle a lot of peripherals, but i haven't found any technical docs yet (didn't look too closely), maybe pine64 has already gotten some

dear people. is anyone here familiar with a A83T board using x32 LPDDR3 memory ? I'm looking for some good examples for my own board-in-progress.
<apritzel>
jernej: do you feel like posting the first part of your v2 U-Boot HDMI rework patches? Up until and including "de2: switch to public uclass functions"
<apritzel>
jernej: then we could ask Anatolij to merge them now, and you have those off your back

JoaoSchim: what is the problem with your board's DRAM? LPDDR3 on A83T should be supported, for instance the Sinovoip BPI M3 seems to use that

apritzel: Yes indeed, i have used the defconfig for BPI M3 as a template. Just not sure what memory it uses. I thought it was x16 width. Currently i just get DRAM: from u-boot SPL. looking for ways to determine whether its configuration/code or hardware issue.
<apritzel>
JoaoSchim: ah, it looks like the driver only supports 8 and 16 bit bus width
<JoaoSchim>
Aha, that would explain, so i need to do some coding..
<apritzel>
it might just not be tested, so you can try to naively enhance to code to consider 32 bit width as well
<JoaoSchim>
thank you apritzel. I will look into it. Other than https://linux-sunxi.org/DDR3 is there any good refs on lpddr3 for Allwinner you know off ?
<MoeIcenowy>
you can get that bus-width-related code is just copied from A33
<MoeIcenowy>
and is wrong

yeah thanks i found it. no component numbers though.. but indead 1x32 layout for sdram.
<JoaoSchim>
thats a match..
<apritzel>
JoaoSchim: the wiki has a hi-res picture of the board, with a bit of squinting you can make out the part number

found a small difference between the SDRAM BPI M3 and mine. My SDRAM has 2 dies. while BPI has single die. don't known what that entails though..

JoaoSchim: so is this a dual-rank DRAM in a single package, then?

looks like it. I have a micron mt52l512m32d2pf-107 on board.
