cubieboard 3 rtc & nand

[Alexey July]

Hello all) 

Please, need help.

Minimal/IOT images with Armbian Linux v6.6
Debian 12 (Bookworm)

 

1. I try configure cubietruck with armbian 6.6, but in system not see nand0 and broken rtc0. 

When start nand-sata-install i see only "install on sata" and not find /dev/nand .

2. If i try: 

rtcwake --mode mem --second 180

in console view error

cannot open /sys/class/rtc/rtc0/device/power/wakeup: No such file or directory
/dev/rtc0 not enabled for wakeup events

 

How i can fix it?

I believe the nand is not supported. This is not a great loss as it is flaky and unreliable.

 

Not sure about the rtc. Do you have a battery?

AFAIK NAND support never made it upstream. Therefore its support was lost when getting rid of stone-age 3.14.y bsp kernel.

Either life without NAND or dig deep in the archives to find a very old image that still has this old kernel.

Yes, I installed a new battery from a laptop. Before that, there was a small battery.

If I remember it right, NAND problems were related to a weird original configuration where it was divided into two parts. First part was used "as is", but the second used eec or some kind of scrambling. First part had U-boot and maybe uImage while second part had everythin else.

 

This structure was not easy to be used by third part developers.

 

I have myself a configuration where U-boot and U-boot environment still stands on NAND, but everything else is on SATA disk. U-boot version is 2019.04 because I did not manage to make any more resent version work. Advantage of this conf is that I can boot it without SD card.
