Hi palica,

Thank you for this. At first, I miss the modification about the link to modify ...
This is really a great job !

Adding the dialog package, may help to have a more friendly wifi configuration with wifi-menu.

How do you compile the kernel ? Is it cross compiled ?

Again, thanks a lot for this nice job !

I found some missing feature:

- I cannot set clock : /dev/rtc does not exist.
- The micro-sdcard (behind the battery), does not seems to work.

I'm using it in console mode, and it's very stable (although, not having the clock set produce some issue)

Hi, mfc_alpha,

the kernel was compiled on a Odroid-XU. I will try to add the dialog package and reupload the image. Putting it on my TODO list :)

If somebody is willing to make changes to the image and/or kernel, please be welcome to do just that.
The kernel is on github so everyone could contribute and maybe move it more towards mainline compatibility.

I am pretty sure you can update the time on that image. RTC is not present on efika board, but that shouldn't stop you from adjusting the time after boot (manually or using ntp once connected to the internet).

the rear sd card ... that one i don't know. I haven't tested it.

Palinca,

Ok, the rear sd card is working. The card have to be insered before booting (So you need to modify the bootscript).

About the clock, ntpd is running and can change the time. But changes are not persistant.

I'm trying to compile the kernel.
- Compilation fail for firmware/sdma-imx51.bin but instead copying an existing one (e.g. from your system image) solve the issue.
- I try to cross-compile but I still have issue (comming for the compiler which is hf?)

Hi,

I've compile the kernel on the efika, but replacing the kernel of your image by the result of make bzImage produce just a black screen ...

Here are the step that I've followed:

zcat /proc/config.gz > .config
make bzImage
cp arch/arm/boot/zImage MOUNT_POINT/linuximage

I'm on sacha's git. branch work/efikasb. Commit 4de30514cbd


Any Idea ?

thanks

You have to regenerate also the DeviceTree and copy that alongside the new kernel. They are located in arch/arm/boot/dts directory once you compile your kernel.

Let me know if that worked.

The generated dtd is binary equals to the one your provide (named oftree).
So even changing it does not help :/

Hi,

these are the scripts I've used to generate the DT.

user $ cat uImage-dt.sh
Code:
#!/bin/sh
ver=`cat include/generated/utsrelease.h | sed -r -e 's!.*"(.*)"!\1!g'`
k_image=arch/arm/boot/zImage

rm -f ikernel
devio > "ikernel" 'wl 0xe3a01cff,4' 'wl 0xe38110ff,4'
cat $k_image >> ikernel
cat arch/arm/boot/dts/imx51-genesi-efika-sb.dtb >> ikernel

mkimage -A arm -O linux -T kernel -C none -a 0x90008000 -e 0x90008000 -n "efikasb-$ver" -d ikernel uImage-dt-$ver
rm -f ikernel
user $ cat uImage.sh
Code:
#!/bin/sh
ver=`cat include/generated/utsrelease.h | sed -r -e 's!.*"(.*)"!\1!g'`

rm -f uImage.loco uImage.efika
#mkimage -A arm -O linux -T kernel -C none -n "efikasb-$ver" -a 0x70008000 -e 0x70008000 -d arch/arm/boot/zImage uImage.loco
mkimage -A arm -O linux -T kernel -C none -n "efikasb-$ver" -a 0x90008000 -e 0x90008000 -d arch/arm/boot/zImage uImage-$ver
I hope it helps.

Palica

The github repo with Linux 3.7 will likely push me to learn cross-compiling and attempt to resolve some of the issues in the Fedora release.
