I had an attempt and building mainline uboot, adding in the N2 support and building the ATF firmware to run uboot.  I did not have uboot working (some issues not long after uboot is started,  I think I missed reserving memory) but I did manage to work out how to format the amlogic firmware to start uboot.  It was a bit more complex and messy than the C2 process but can be scripted easy enough I believe,  we would need some compiled blobs from the hardkernel git still I think for the moment as in the C2.

 

I will keep trying uboot as baylibre add support for the g12a there.  Would be nice to have mainline running on the SPI as many more possible features for booting images.

I added to the site new images 5.87 for N2 with kernel 5.1 which already have the necessary scripts to start the activation of multi-boot (n2_autoscript) and start the system from USB (boot.scr).

If activation is already done, then after burning the image to USB media, you do not need to add\change anything. When you connect to N2 in the USB stick, the system automatically starts up. By the way, I checked the fast USB 3.0 flash drive on N2 , the speed is higher than the SD card. And when using USB-SSD , much faster than eMMC. :)

 

 

p.s.

After comparing the operation of the system with eMMC and with a good USB-SSD, I concluded that eMMC is not needed for N2 at all. :)

Gathered and checked the startup script of the system Armbian kernel 4.9. Everything works. Scripts on the site are marked according to the kernel used. Before using these scripts on existing systems, be sure to rename them correctly after writing to USB media. The file name must be boot.scr.

 

In the new images Armbian 5.87 these scripts are already in both versions of the images and not to add in the is not necessary.

 

When you start the system from an SD card or eMMC with a new u-boot , in the "boot.ini", you need to comment out or delete this line .

I've tried again, but no, it still doesn't work. It seems a different U-Boot present in SPI which doesn't check keystrokes ...

Yes, I've seen this behavior. By the way, connect the image with the kernel 5.1 and you will see the work of the monitor\TV with the message of the reason that it was not possible to mount the root system. Piteboot will even show the available system on USB\SD (if they have the correct "boot.ini" from which it tries to read and form its startup script). :)

 

By the way, on the old version of Piteboot (20190202) I normally started systems from SD card in u-boot SPI mode.

Although I have SPI/USB combo working, I've continued investigating about the eMMC ...

 

Now, I'm throwing the towel !!! :angry:

 

Just for example, few days ago, I was trying to push image to eMMC using "xzcat theimage.img.zx | dd of=/dev/mmcblk0 bs=100M" and it hangs with "load average > 10" forever.

Then I extracted the image, and did "dd if=theimage.img of=/dev/mmcblk0 bs=100M", it success, but the eMMC didn't boot, hanging early after mount ROOTFS.

I've suspected corruptions, confirmed with "fsck", so today I tried to restore manually doing "tar cf - <source> | tar xvf", from working USB to eMMC, but again "load average > 10" forever.

I did only few directory at a time, fine, the tar finished, but doing "sync", again "load average > 10" forever ...

What the F*%K !!! And as cherry on the icecream : this eMMC can't be used with the eMMC/USB adaptor I've coming from RockPro64, although mechanically compatible, and looking at schematic should be also electronically compatible.

 

So, end of the story, I will stay with SPI/USB combo like @balbes150 suggested !

What model eMMC is it? Is it a pine one? I've had issues with Odroid eMMC working on pine, but Pine eMMC not working on Odroid or RockPi.

Always a simular behaviour of showing initial boot and then hanging. If you've got another. Try it. Mine with problems has V 1.0 written on the underside. Works with some, most not.

Nope ! It is eMMC part of the parcel shipped by Lisa's HardKernel DEV sample recently received.

I maybe going to restore original 4.9.162 to see if such "load average > 10" exist on their image ... (But now I  have doubt how I will be able to restore it)

I have an eMMC module from HK (was bundled with N2). I haven't tried it yet. I'll try to test it with the image Armbian in the course of the week.

I didn't see the emmc issue on N2 with the 5.0 based kernel,  and I did try a few different emmc's & sd's.  I'm currently trying to see what minimal patches I need to apply to 5.2-rc to have a booting kernel.

Just to let you know, I've been able to restore original 4.9.162 image on eMMC and booted it ...

Then, I've done some test of doing "tar | tar" of almost all ROOTFS into a new folder without any "load average > 10" issue.

So, it is most probably a kernel issue within 5.1.y image. I've compared mmc nodes of both DT, I didn't find much differences ...

I've just faced a new issue : since I've restored eMMC with 4.9.162, even if I place the boot switch to SPI position, U-Boot doesn't report anything while doing "usb start", although "usb tree" is working fine. :wacko:

So, I can't boot from USB anymore if eMMC is present/connected ... :( To be able to boot from USB while eMMC is present, I had to wipe out the eMMC, filling its first sectors with zeros ...

Strange AmLogic boot sequence ... :angry:

 

EDIT : Even worst ! If I re-create a simple data partition on eMMC, "usb start" doesn't work anymore ... :angry:

The only way to make both co-exist is to have a duplicate BOOT from USB into eMMC, simply because this poor U-Boot is still looking at /dev/mmcblk0p1. :blink:

 

EDIT2 : No, it is not the BOOT partition that produced such behavior, since I was able to delete all partitions and recreate only one for data. So it is most probably the presence or not of the bootenv sectors ! :angry:

I've had something very strange with it when leaving the eMMC in with Ubuntu Mate. And putting SD-card with Meveric's Stretch in. It did boot stretch, but with the kernel of Mate.
So best to leave the eMMC disconnected when using an SD-card.
See here : https://forum.odroid.com/viewtopic.php?f=179&t=33865

The post of mine(badpritt) with 2 pictures in it. Then Meverics response that it wasn't his kernel...

To make it easier, here the post of Meveric :

Your Kernel looks very odd...

Linux odroid-stretch64 4.9.162-22

That is none of my Kernel.

Also now that I look at the picture I see you have eMMC and SD card connected at the same time...

Could it be that you have Ubuntu and Debian connected at the same time?
If so, please remove the Ubuntu image, as you will have lots of issues with this combination.
This would actually explain a lot of the issues I've seen in the syslog that I was confused about... like missing /lib/modules/ folder.

Try removing the u-boot loader from the eMMC and remove the startup scripts (boot.ini).

As I said, I've removed all partitions, and still work, as long as I keep the u-boot and bootenv sectors. If I do "dd if=/dev/zero of=/dev/mmcblk0 bs=1024 count=1000", then, from SPI U-Boot, "usb start" won't work if the eMMC is present, even if boot switch is at SPI position. So, my conclusion is that U-Boot still use eMMC bootenv, even if switch is at SPI position, and if eMMC bootenv emptied, it chokes ! If eMMC isn't present, it fallback reading the bootenv from SPI instead.

Hooked module eMMC (blank) to N2. Switch to SPI. Starting Armbian from USB works without problems. Created a partition table and two partitions (FAT and EXT4) on eMMC . Reboot N2. Everything normally starts from USB and SD card. I haven't checked the system for eMMC yet (I don't have enough time).

Are you sure it is blank (no bootenv sectors left) ?

Because I've repeated the scenario twice, and as soon I'm erasing the bootenv on eMMC, the "usb start" do nothing (no output at all) and comes back to u-boot prompt silently.

 

EDIT : I've even checked with an ohmmeter if the Boot switch was properly doing contact in SPI position, and it was Ok ...)

 

EDIT2 : I've checked the schematic, and this SPI Boot switch only add a 10K pulldown to eMMC_D6, schematic is Rev0.1, while my board is v0.4 ... Which Rev is yours ?

 

EDIT3 : Ok ! I've tried to repeat tests a third time, I was wrong, the symptom occurs when u-boot/bootenv sectors of the original 4.9.162 are present.

But still, why if the switch is at SPI position, the AmLogic BROM still load something from eMMC ?

 

EDIT4 : In fact, I was partially right : If eMMC is blanked, then create a single ext4 partition, but using default fdisk start at 2048, it produce the same symptoms ! But not at 8192 ...

 

EDIT5 : If I remove the partition starting at 2048 and redo it at 8192, symptoms are still there, until I pushed zeros around that location 2048 !

I forgot to write in the first message about eMMC that I always create partitions with an offset of 4M.

 

New test results. :)

Added files to the images to install the system in eMMC. Checked the Armbian installation with kernel 4.9. Everything was installed and when you restart properly run system from eMMC. Further an interesting outcome. The system startup from USB stopped working. Running from SD card works. When installed on eMMC, only system files were copied, u-boot did not copy. When clean the first 4M for eMMC, start with USB again earned. Now I have collected new images with the addition of the installation script in eMMC and a new option to activate multi-boot (changed the order of polling MMC), now the order of polling boot such

1. USB 

2. SD card

3. eMMC.

This ensures that the external system starts from USB\SD if there is a breakage with the start-up from eMMC.

Just to let you know, I've tried this custom "nand-sata-install", and I've faced the "load average > 10", and the install didn't finished, even after 1 hour... :wacko:

This still works on kernel 4.9. The 5.1 kernel needs patches.

What do you mean ? Is it a DT issue or some things in eMMC driver itself ?

On S905x2 (it's a close platform with S922) eMMC works with this kernel. Perhaps the reason for the settings or is it the result of using a removable connector for the eMMC on the N2. I noticed that if you copy the data in manual parts no more than 500MB, with an intermediate "sync" , everything is copied correctly.
