I am try to build a xenomai kernel following this url
https://github.com/cdsteinkuehler/linux-dev ,
<http://brunosmartins.info/xenomai-on-the-beaglebone-black-in-14-easy-steps/>
RCN Kernels with Xenomai patches added.
I use linaro 4.7 hf,and compile pass correctly.
I get the zImage and dtb modules file, and I copy it to a SD card
with ubuntu 12.04 rootfs.
and boot form the sdcard. I got this error:
--------------------------------------------
gpio: pin 55 (gpio 55) value is 1
invalid extent block
mmc_send_cmd : timeout: No status update
** File not found /boot/zImage **
Booting from internal eMMC...
gpio: pin 56 (gpio 56) value is 1
** File not found /boot/dtbs/am335x-boneblack.dtb **
Bad Linux ARM zImage magic!
------------------------------------------------
it back to uboot command line .
This sdcard boot fine with a normal bbblack kernel zImage,
The precompiled kernel(with xenomai) zImage provide by machinekit on url
http://static.mah.priv.at/public/beaglebone/starterkit/
<http://static.mah.priv.at/public/beaglebone/starterkit/OUTDATED/>
which is name with bone53 is also boot correctly.
I try to ext4load mmc 0:2 0x80008000 /boot/zImage, and got the error
"invalid extent block".
I can't understand why it seem to not find my zImage file ,
ext4ls show the file is just there and the size is correct.
