BeagleBoard C2 stopped booting

Dear All,

I have a BeagleBoard C2 which were functioning properly for a long time
for now.
Today I have compiled a new kernel and replaced my Ubuntu 11.10 official
kernel with my optimised version.
It seems taht something went wring so now my BB hangs after loading
u-Boot. Does not start to load the kernel and no u-boot prompt is available.
Find the output of the console below.
I have tried to hold the User button while booting, but no difference.
I have also created a new official Ubuntu image on an other SD card, but
unfortunately no change.

Can anyone suggest me a solution how to fix this issue?
I really hope that my card is not bricked.

Thanks in advance.
Best regards,
Blaise

Here comes the console output:

Most of the time there are issues with MLO and u-boot.bin files. Recently I also faced many troubles with these files.
Try with these files.
I have uploaded working files for me, you can try them.

Thanks very much for your quick answer and help.
Yes, copying the files you have provided for me onto card my BB
started work.
I currently can use the uboot commands and everithing seems to be
fine.
I will replase the MLO and the u-boot.bin on my OS card and try it.

Thanks again for your kind support.
