Beginners / Cubieboard S/PDIF port as INPUT?
« Last post by bcattle on April 29, 2018, 06:08:36 pm »
Hey all,
Is there any way to configure the cubieboard S/PDIF port (Toslink) as an input? Do any Cubieboard models support this?

Thanks,
Bryan

Cubieboard v1 OS (A10 Based) / Armbian Bionic 18.04 LTS for Cubieboard 1
« Last post by slovenia on April 27, 2018, 07:02:12 am »
How does Armbian based on Ubuntu 18.04 Bionic looks like? The same as Xenial, Jessie or Stretch :) How does it function? As fast as possible. Can I build my own image? Yes, you can. Since board is officially EOL you need to use switch EXPERT="yes" when building an image.

More info and download links:

Same problem. Any solution?

So I'd say you've probably got the best setup at the moment.

Best is a bit strong word, but it definitely fulfills my needs right now.

In my present installation kernel version is 4.14.7-sunxi. Only U-Boot is on NAND. Kernel having initramfs and modules are all loaded from SATA. My goal was to get rid of SD-card and this does it.

However kernel version 4.9 did show NAND but the present 4.14.7-sunxi does not.
Thanks for the info.  What you've got now sounds like a new version of the setup I use which is U-Boot on NAND and everything else on SATA.  I went this way because they say NAND fails after many writes and so I figured the best thing to do is just keep static boot stuff there and get everything else from disk.

I haven't bothered updating from my old Wheezy system because it works well and supports NAND and the AP6210 (Wi-Fi).  The new Armbian kernel (4.18) supports the AP6210 but not NAND.  I can't get it to load with an old U-Boot.  But the Armbian release (stretch) will compile the new U-Boot which is good.

I've been away from all this for over a year and things certainly have changed.  People seem very critical of NAND and I guess it's not as good as was hoped.  So I'd say you've probably got the best setup at the moment.

Cheers,
Steven

Please check 'lsblk' in your 4.7 kernel and tell me what it detects.

Hi,

I don't have it installed any more, but maybe you should use the same version I did. It's here:

https://github.com/bbrezillon/linux-sunxi/tree/bb/4.7/ubi-mlc

It seems to be vestion 4.9 even though name would suggest 4.7.

In my present installation kernel version is 4.14.7-sunxi. Only U-Boot is on NAND. Kernel having initramfs and modules are all loaded from SATA. My goal was to get rid of SD-card and this does it.

However kernel version 4.9 did show NAND but the present 4.14.7-sunxi does not.

If you want the exact source code I used to make this U-Boot and 4.9 kernel, just give me some email address to send them. I have FTP server here, but it would be extremely slow.

I've got the same problem. Did you find a solution?
Seems that only sistem apps are mantained.

Здравствуйте

Помогите, пожалуйста, с диагностикой.
После выключения питания Cubieboard 3 (cubietruck) не включается. LED, рядом с гнездом питания не светится.
Проверялся на разных, заведомо исправных блоках питания.
Напряжения с тестпоинтов:

Что могло "вылететь" на плате?

Still there is not a way to use NAND as boot device for the whole system, but this should be possible by just flashing kernel in raw mode in NAND and loading it with UBI drivers from there. Then the rest of the userspace could be put in UBI.
I've been through the config options in the 4.7 kernel you mentioned but I find any way to get it to support NAND.  With your CT does 'lsblk' show any NAND partitions ?  I'm thinking it's unlikely that any kernel can be booted from NAND if it can't access the NAND.  For instance, how could it load modules ?

I've installed an Armbian kernel with stretch on a CT and can generate U-Boot.  I'm still sarching for config settings so it can access NAND.  I'd like an SD-card version that can load my old kernels in NAND.

Please check 'lsblk' in your 4.7 kernel and tell me what it detects.

Cheers,
Steven

Any suggestions what to do next to get it booting the whole way up?

OK. Needed second eyes again to make it work. My son has so much younger eyes ;)

I did not have .next file in /boot folder. It did try to boot old kernel. This prevented it coming up.

Now I have U-Boot and U-Boot environment in NAND, but everything else in SATA-disk. It boots without MMC-card as I wanted it to be.

Still there is not a way to use NAND as boot device for the whole system, but this should be possible by just flashing kernel in raw mode in NAND and loading it with UBI drivers from there. Then the rest of the userspace could be put in UBI.


B.T.W I did put SPL and U-boot in first erase block and environment in second just to be able to erase them separately.

The above attachment having U-Boot config has at least one error. Nand setting block size has to be added one more zero. Even with this corrected I did not manage it to work. There has to be something weird in scrambling bits.
