Does this device need extra power supply? As I know, some PCIe devices need that (e.g., Intel® 82575/82576 4 port ethernet card). Or, could you test other devices?
It’s a half size mini PCIe card so no extra power supply is needed. According to the product brief ( https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/dual-band-wireless-ac-3160-bluetooth-brief.pdf ) it supports PCIe and USB. On the BPI-R2 schematic that is available currently, the USB lines on the mPCIe socket are not connected (so USB-only mPCIe cards are not supported like most of the 3G mPCIe as far as I know) but the 3160HMW should (?) be visible in the lspci output.
More console log could be helpful. We need to know what happened when PCIe linkup.
Can you please share us the linux kernel booting log while this card is installed?
Has anyone actually tested this? I followed the instructions, and the board doesn’t boot from emmc.
I need to build a new card in order to do so (I’ve overwritten the previous one), I hope I’ll find some time to do it soon.
Can you please try the following steps: How to boot from eMMC:
-
boot from SD
-
sudo su
-
echo 0 > /sys/block/mmcblk1boot0/force_ro #enable /dev/mmcblk1boot0 write mode
-
To write preloader to EMMC by running command:
bpi-bootsel BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz /dev/mmcblk1boot0 -
To copy ubuntu image to EMMC:
unzip -p <XXX.img.zip> | pv | dd of=<device> bs=10M status=noxfer or bpi-copy <XXX.img.zip> <device> where the XXX.img.zip is ubuntu image we can get it from http://www.banana-pi.org/r2-download.html, and where <device> should be /dev/mmcblk1. -
poweroff
-
remove SD & power on
Hello @ all,
i read the thread and follow the instruction:
boot from SD
sudo su
echo 0 > /sys/block/mmcblk1boot0/force_ro #enable /dev/mmcblk1boot0 write mode
bpi-bootsel BPI-R2-EMMC-boot0-0k.img.gz /dev/mmcblk1boot0 #write once
bpi-copy 2017-09-04-ubuntu-16.04-mate-desktop-bpi-r2-sd-emmc-v1.2.0.img.zip
poweroff
remove SD & power on
but does not work. After Power on, ther is Nothing to see in the Debug Console … what´s going wrong ?
Best regards, René
Does any error come up while calling bpi-copy? Any ubuntu-image was bigger than emmc and fails there…then image must be resized first
nope, but uboot does not known the command “emmc” …
“emmc ecsd” or “emmc pconf 0x48”
BPI-IoT> emmc ecsd
Unknown command 'emmc' - try 'help'
BPI-IoT> emmc pconf 0x48
Unknown command 'emmc' - try 'help'

Is there a Firmware update ?
then you have to update uboot first to actual version…
you can use my compiled version: https://drive.google.com/open?id=11XQ4n6WYSj7gGPtMwug4SITtYn0GZxOb
and install like this http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:uboot#update_uboot or using bpi-update
but last ubuntu should be have actual uboot, too… 
The emmc-command is integrated in uboot since September 29th 2017 (version: “U-Boot 2014.04-rc1 (Oct 16 2017 - 19:33:23)”)i’ll check you wiki.
But /dev/sdx ? do you mean /dev/mmcblk ?
you must flash the image on host-pc to sd-card (where you boot first you bpi) not from the bpi itself…
i used the bpi-r2 … and it works
you’ve wrote image direct to emmc (which partition)? or to your sd-card?
ubuntu boots from emmc without sd-card?
@garywang: is it possible to load uboot from emmc, boot from SD if inserted and if not using emmc-boot?
It doesn’t work so far.
yes, it’s possbile, but we have to modify some code in uboot.
