[PATCH 1/1] ARM: dts: sunxi: Add a olinuxino-lime2-emmc

[Olliver Schinagl]

There are 3 kinds of OLinuXino Lime2 boards.
One without any on board storage, one with NAND storage and one with
eMMC storage. This patch adds the eMMC variant of boards.

eMMC storage is different from a regular SD card in that it is soldered
on the board and cannot be changed. Additionally, it shares pins with
the NAND module and with the second SPI port.

Is it a publicly available board, or is it a private hack you made
yourself?

Only 4 bits? We normally see eMMC with 8 bits. 4 bits are some kind of
embedded SD card.

This flag is not supported on sunxi.

Instead, use the vqmmc-supply with the correct regulator and constraints.

On A20 as well? Our investigations so far have concluded that the A10 
and A20 have those pins not mapped out to pads. The IP does support it 
however we assume.

You're right. My bad. First time A10/A20 sees eMMC support.

I can't say anything about A10/A20, but I have a board with A13 and
the same eMMC chip and it works fine in 8 bit mode.

Yep, sun5i actually brings them all out to pads, the A20 however does 
not :( We first thought that the A20 would also be an 8bitter, because 
the mmc IP appears to be the same as sun5i, but initial tests show it is 
not. As for A10, it has older IP and it might not even support 8 bit 
mode, let alone bring out the pins.

But with A20's + eMMC being available via the lime2, others may repeat 
my experiments! The lime2 is 8 bit connected.

Hi Olliver,

Why are you using nRST signal?
What I mean is this pin is inactive on this eMMC chip. To use the signal 
byte 162 of ECSD registers should be written.

On my board, this "reset" signal causes eMMC not to work.

Best regards,
Stefan Mavrodiev

Then that sounds like a bug in the mmc layer I would say (or a missing 
attribute in the dts), we have a nRST signal it is wired, if the chip 
ignores it, then nothing lost, if the chip needs to be initialized with 
byte 162 of the ECSD register to make the nRST work, then that it sounds 
like it should be fixed there?

By ommitting the nRST signal just because the chip isn't properly 
initialized sounds more like a work-around to me, but I could be wrong 
and see things wrong.

What do the mmc guys, who have far more experience here, say?

Hi to All,

I have already solved and tested this issue on Armbian build.
Find patches for both legacy (3.4.111) and mainline (4.5.2) kernels on:
http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7494
There it is also described how to do eMMC bootable and much more.

About the board - Olimex already sold all 3 kinds after migration to their HW rev. E. One have to specify Lime2-eMMC as A20-Olinuxino-Lime2-eMMC instead of their old 2 options A20-Olinuxino-Lime2(-4GB).

Regards
Chris

Interesting, you have a link to that device?

Thanks,

I have really 2 boards delivered by their local distributor.

Unfortunately, they do not update their site. Use the link for NAND option:
https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2-4GB/open-source-hardware
There you can find Users Manual where it is described that eMMC option is available from HW rev. D. The schematic for HW rev. E is also available on their repository:
https://github.com/OLIMEX/OLINUXINO/tree/master/HARDWARE/A20-OLinuXino-LIME2

On the board both 4GB NAND and eMMC Flash chips can be placed alternatively on the same place. There is difference in some other components as well.

If one want to order it from the site probably has to order A20-Olinuxino-Lime2-4GB with note that eMMC option is required. The price is the same.

Sorry for the late reply, but yeah the board exists, we asked Olimex to 
develop the eMMC variant for us. I currently have a dozen or so on my 
desk :)

I don't know when Olimex will update their webshop with the new designs, 
but they simply might not have enough eMMC chips available yet?

I guess, it is this one:
