NanoPi Neo Core 2 eMMC not recognised after booting from SD

[gq0]

Hi guys, 

 

I am trying to install `ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.14.14-sunxi64` to the internal MMC with `nand-sata-install` but it seems that the internal MMC is not available after booting from SD.

 

I tried to set the `sdc_detmode` as described here: https://forum.armbian.com/topic/1702-orange-pi-plus-2e-where-is-16ghz-and-sd/?tab=comments#comment-13163

But there is no `script.bin`.

 

Any idea on how to flash the internal MMC on a Neo Core 2?

 

Cheers!

Robert

Exactly which image have you used?

[gq0]

I used this one:

https://dl.armbian.com/nanopineoplus2/nightly/Armbian_5.46.180602_Nanopineoplus2_Debian_stretch_next_4.14.47.7z

 

I followed the download path here:

There are very slim chances that our images don't work. Is your board the same as on the picture below?

This image works perfectly fine: 

Boot from SD: http://ix.io/1dMY

Installed and booted from eMMC: http://ix.io/1dN5

It looks that we have the same board revision:

 

I connected it to a shield but other than that it should be the same:

 

Now I tried to use a DT (mainline) based on the Neo2 with features from the Neo Plus2. This is what I added to the Neo2 DT in terms of the MMC interface:

&mmc2 {
	pinctrl-names = "default";
	pinctrl-0 = <&mmc2_8bit_pins>;
	vmmc-supply = <&reg_vcc3v3>;
	bus-width = <8>;
	non-removable;
	cap-mmc-hw-reset;
	status = "okay";
};

And it seems to work.

I have the same core 2 and mini shield.

 

for me, Armbian does not work, when LED blinks but PUTTY cannot establish sessions.

 

Tried official ROM but canot have LAN or USB WIFI, how do you solve this problem? I am doubting my mini shield failed but it is very rare that this could happen

 

Core 2 LED blinks and shows boot without problem, but PUTTY cannot establish sessions, and this is a big trouble and I have no access at all.

 

Plz help

Have you tried hooking up a USB-serial connection to the board so that you can log in and see what is going on, check/configure networking, etc.?
