you could probably cherry-pick the mmc fix on top of it...

well, i want to get it boot first, then care about mmc and whatever else

i want to get ubuntu snappy running on this platform and for this i need to be able to compile u-boot. BSP u-boot does compile but not boot because of all the fex stuff which is either not there or wrong ..

Hi. Recently I found that on an A20 device, If I start an Xserver and let DPMS turn off screen, SoC idle temprature could drop by ~2 degrees C. Anyone noticed this?
<vickycq>
IIRC the A20 soctemp sensor is embedded in touchscreen controller. Could this be related?
<vickycq>
I tested on a total of 4 A20 devices, and I would say this is quite reproducible.

longsleep: that mmc fix was not a correct one
<ssvb>
more specifically, there are two bugs which cancel each other and the problem needs to be solved in a different way
<vickycq>

<vickycq>
...and I have to start an Xserver to turn it off ;)

yeah.. because u-boot initialises it

<longsleep>
longsleep: I mean i failed getting the BSP u-boot running, but it works pretty good with the binary blobs of the provided android image. I could get snappy working with those, but i would much prefer to be able to build everything from source. Do you have any plans yet how to solve the libdram problem?
<longsleep>
ssvb: I just tried to combine your u-boot without spl, with the boot0 blob then found that they check the u-boot header in there ..
<ssvb>
longsleep: pine64 people are discussing it with allwinner now

and if nothing comes out of it, then we just will have to reverse engineer libdram

Most of the boards with audio jacks do not have any good audio though
vishnup_ has joined #linux-sunxi
<Rambler44>
I think the issue was that the USB devices were drawing too much current so the audio would get distorted from the lack of sound or possibly processor overload
<Rambler44>
Some boards are better in this regard if the audio has a dedicated low-noise PS
<WarheadsSE>
longsleep: odroid-c2 when it is out?
<Rambler44>
Most boards just have a HDMI, but my guess there is no HDMI to 3.5mm audio jack converter out there

I saw some HDMI-VGA devices too but I wonder what audio quality that will give depending on what is onboard?
<wigyori>

<Rambler44>
HDFury released some HDMI 2.0 4K cheat by converting down to the lower HDMI protocol and DHCP which was already cracked

Comapred to A64 its not Cortex-A53 still A7

<Deskwizard>
I don't recall of the top of my head either, wasnt A53 bigLittle ?
<Rambler44>
I think that was some kind of mix between A53 and A7
<Deskwizard>
The Cortex-A53 delivers significantly higher performance than the highly successful Cortex-A7, and is capable of deployment as a standalone applications processor or paired with either the Cortex-A72 or Cortex-A57 processor in a big.LITTLE™ configuration for optimum performance, scalability and energy efficiency.

I've been trying for a few days now to get u-boot loaded onto NAND and actually booting here on my Olinuxino A13 which is an Allwinner CPU so the sunxi side of things. I've had no such luck using the 2016-01 RC2 nor the CHIP u-Boot branch, which is based off the the R8. My understanding is SPL replaces boot0 / boot1 for Allwinner/sunxi boards.
<expresspotato>
The board uses 8K page sizes with 640 B OOB. ECC Strength is reported online as 1024/40 and I've changed the dts to match as there are a few floating around online for the A13. There are 3 ways I've tried to get u-boot with SPL loading from NAND and none of them have been successful.
<expresspotato>
Any advice?

The current U-Boot release (v2015.10) fully supports major functions (except NAND) on all the older Allwinner SoCs (A10/A10s/A13/A20/A23/A31/A31s)
<expresspotato>
hi, so that post makes reference to linux-sunxi which is just the linux kernel and flashing nand using mtdwrite. I've flashed it using mtdwrite and read it back using mtd_debug and a nand dump from u-boot, they're all the same with respsect to the SPL loaded into the first 3 blocks of NAND.
