Linaro problem

Hi, i have followed this tutorial:
http://www.digilentinc.com/Data/Products/EMBEDDED-LINUX/ZedBoard_GSwEL_G...

the ramdisk file system works great, but whe i do the appropriate change for the linaro file system the serial port output this:

Corrupt ramdisk?

The thing that leaps out at me in your log is that uboot is unable to correctly copy the ramdisk to non-volatile memory.   I think resolving the reason for that error is the key to getting your system to boot correctly to the command prompt.  Could be a simple as using a different SD card.

Hi,

Hi,

Have you checked your device tree? The chances are that some hardware which is available in the default bitstream can't be found in your hardware design which is causing a driver to fail (for example the OLED screen). There's a good tutorial for this here:

thanks for the reply, now it

thanks for the reply, now it seems working, but when i do
insmod myled.ko
nothing happen, in proc directory the myled file doesn't appear, but if i do lsmod the myled module is correctly loaded, could it be a device tree problem?
