K-R42 - wasser firmware - JB Android 4.2.2

[franckleroy]

Hi all.

i'm uploading 1.2.2 firmware for k-r42. It will be available sonn for download.
Some changes in the new firmware:

- new kernel
- improved suspend/resume, stability
- improved video playback
- fixed audo issue
- fixed key mapping issue
- support all revisions (you have to choose the correct one)

important:
- please erase NAND (click EraseIDB button) before flashing the firmware

Can you in your next kernel set this :

• CPU speeds: 1200/1608MHz
• DDR speed: 720 (=1440MHz)
• GPU speeds: 400/600MHz
• Default governor: ondemand
• Default i/o scheduler: noop

In current 11/11/13 CPU is only 1400 and noop is not present.

Thanks
Franck

Hi wasser

this afternoon I made a lot of test :

Jesurun PCB 2.1 do not accept kernel 11/11 (new revision ?)
Lan only works with kernel 01/11

k-r42 PCB 2.1 from geek buying, works with kernel 11/11, playback is smooth but not as on x7mini with molle kernel.
May be CPU/GPU settings are too low.

In both case eth0 speed is about 50mbits/s.

Hope this helps !
Franck.

just tested the newest firmware.

Have audio again!!!!

Lost LAN again

Anything I can do to assist in testing?

also, do I always have to erase NAND when testing out different firmwares? whether yours or lewy's?
thanks for the hard work

you have to choose the correct firmware to flash, if you have k-r42 revision 2.1 you have to choose the k-r42-new_revision-wasser-1.2.2.zip

i have k-r42 old revision and lashed k-r42-old_revision-wasser-1.2.2.zip. Lan/Wifi works fine for me

which revision do you have and which firmware did you flash?

thanks

Yup, I see. I read too fast. Just downloaded "new" version

yes, it's required! the firmwares are diffenrent

wasser: new revision is working great so far.

I tried searching for this next question, but maybe i'm not using good search words. Bare with me, if this has been covered somewhere else. I see many mentioning using mx player. I downloaded it, but i when I try to open it it says no sd card. I do have an sd card and it shows the card in the storage settings. Was i supposed to do something for the device to use the sd card?

Thanks

install new revision ....very slow wow like using a pentium1 with 128 mb ram lol

clean install and erase idb ..what could be the problem? o ya it took 5 minutes to boot too

it seems you flashed the wrong firmware!

which firmware did you flash and which revision do you have?

thanks

it seems you have to format your nand in settings

Hi wasser

flashed old-rev on my jesurun, eth0 works, video with MX player is fine (more tests tomorrow...)

--edit--

flashed new-rev on k-r42, eth0 works with static ip, video with MX player is fine.
Not totaly smooth on 1080p movie due to lack of CPU/GPU clocking

[franckleroy]

you can set it with setcpu app

ok for CPU but how to overclock GPU and DDR ?

-edit- in new rev kernel, max CPU is 1416 ....

no wifi

k-r42 tried both old and new versions of 1.2.2 and no luck 1.2.1 worked fine except for sleep

[no_spam_for_me]

I'm a little bit confused about the OLD / NEW REVISION...
Means old / new the different PCB 2.1 versions OR
means old => 2.0 and new => 2.1 ???

BTW:
manual nfs mount works fine, but not within es file explorer...

busybox mount -t nfs [I]IP-Address[/I]:/[I]xyz[/I] /mnt/[I]xyz[/I] -o ro,intr,soft,udp,nolock,rsize=8192,wsize=8192

But after each restart i lost my /mnt/xyz ???

mount -o rw,remount /
mkdir /mnt/xyz
mount -o ro,remount /
