Hello !

@loboris thank you for your great job.

Your uImage is way to big, it shouldn't be more than 8MB. (uImage is kernel+initramfs).
I'll upload the new kernels and images later today or tomorrow.

Please add NFS server support to kernel (for debian image) , if it possible.

I had tested internal ...

I think NFS server support is already in my kernel, but I'll check.
You can't expect much higher USB speed on USB 2.0. On my main PC I get max 42 MB/s on USB 2.0, so ~30 MB/s on OPI isn't that bad.
You won't get higher speed using sata to USB 3.0, I've tested it.
You can probably get higher speed using two usb drives in raid configuration, I'll test it.

@loboris,

Just wondering if you can you host the NO_BUDGET_COOLING Kernel in your server and update the update script so we can update it in the new img...

Cheers

Have somebody tried to connect OV5640 CSI camera?
Any success?

I'll do that.

@Sitheek (So I tried to compile kernel ....)
Have you made any changes to the kernel (config and/or source) ?
If yes, could you send me the changes, I can compile the kernel for you.

Thank you.
I did it two times, first time without changing anything, second time I have used your config script to see whether ov5640 support and v4l2 drivers are enabled.
Each time I got over 80 megabytes uimage .
I think I have some issues generating rootfs.cpio.gz which I think is included later in uimage.

I need to try again but for now I will be very grateful if you could compile this kernel for me with ov5640 support enabled and v4l2 enabled too.
I think my .config will not be much help because I am not very experienced in compiling linux kernels, I did it only on Openwrt

I do not change anytching in sources because I do not know what to change ...

Could you tell us what disto you are using for compiling on x86, because my friend tried to compile this kernel on x86 lubuntu and got some syntax error in file arch/arm/mach-sunxi/power/brom/gen_check_code ? (unexpected end of file or something like that)

I did it on x86 debian jessie and everything compiled ok, with a few warnings and mismatches. In debian there is newer version of g++ armhf - from emdebian.org repository !

And one stupid question - do I need to change u-boot each time I install new kernel on BOOT partition? (I think not). Do I need script.bin ?

Have you tested on the mini 2?

I tried the NO-cooling-budget kernel, and applied a fan.

The temperature was pretty low as 32 degrees, but the max_freq (cat from max_freq) dropped soon from 1.53GHz to 1.2GHz after booting into system and never goest up again.

Any ideas of what happended?

Thanks.

The new kernels and images are ready. Most problems are solved including the CPU killing (NO-cooling-budget kernel not needed any more).
Working on all H3 boards (OPI-PLUS, OPI-PLUS2, OPI-2, OPI-PC).
I'll post more information tomorrow.

30 Mb/s isn't bad for me too. But this speed i've got by external controller.
Internal about 12-14 Mb/s.

Will wait for new images !
