Since there is no FW 1.9.17 for mini, this seems to be rather dangerous.

i read that after v2

As of this point, Kobo is releasing different firmware files for each of their products.
Touch is from //download.kobobooks.com/firmwares/kobo3
Glo is from //download.kobobooks.com/firmwares/kobo4
Mini is from //download.kobobooks.com/firmwares/kobo5 (This is a guess. Doesn't work for 2.1.5).

So you mean that the previous ones might not be "generic"?

2.1.4 should work for mini, but it's better to ask in the firmware thread.

[z000ao8q]

just downgraded to 2.1.4.
unfortunately this is also on Kernel 2.6.35.3-850

any other advice to get a lower Kernel (like 2.6.35.3-568) on a mini???

Hi,

I didn't find any specific difference in our configs that could be related to your issue.

When I had a look to rtcwake.c source, there is a check whether /sys/class/rtc/rtc0/device/power/wakeup contains "enabled" or not. When I did a cat on this file sometimes I received a result ("enabled" or "disabled", depending on what I echoed to this file) and sometimes I didn't. Maybe you could give this a try and do an echo "enabled" > /sys/class/rtc/rtc0/device/power/wakeup followed by a rtcwake command.

Regarding your thoughts of buying a Touch to get your things working, I don't think that is the way to go. From my point of view this is just a software issue. If I understood correctly you already tried to downgrade your system with a second SD card. Maybe there is one who can provide you an image of version 1.9.17 SD card. Unfortunately my Touch doesn't have a SD card inside but soldered flash memory.

[root@(none) /sbin]# echo "enabled" > /sys/class/rtc/rtc0/device/power/wakeup
[root@(none) /sbin]# rtcwake -a -s 10
rtcwake: /dev/rtc0 not enabled for wakeup events

I will need this later as well... but i'm not close to this, still stuck with others (compiling qt).

[z000ao8q]

same here. I can not write to wakeup

[root@(none) power]# cat /sys/class/rtc/rtc0/device/power/wakeup

[root@(none) power]# echo "enabled" > /sys/class/rtc/rtc0/device/power/wakeup
[root@(none) power]# cat /sys/class/rtc/rtc0/device/power/wakeup

Grunge,

Am I right that you tried the "trick" on a Kobo Touch (according to your profile). What kernel version (uname -r) do you have?

[Lucas Malor]

Can I suggest you to ask help to specialized forums? I'm thinking about SuperUser or LinuxQuestions, but you can try to search a forum / mailing list specialized in embedded linux. You could also ask some help to Sergey, he had compiled some modules for Kobo.

hello,
can you tell me where you found the rtcwake.c as reference?
I would like to check

[PeterT]

I presume you have looked through https://github.com/kobolabs ?

yes - but it needed some time to learn how the search worked

[Lucas Malor]

You can download it:

git clone https://github.com/kobolabs/Kobo-Reader.git

rtcwake is part of busybox. You can find rtcwake.c source here .
