Hi,
I've been trying to work through Xilinx App Note 1078, without any success.
I'm using the files from here:
http://zedboard.org/design/1521/11
specifically:
http://zedboard.org/sites/default/files/design/xapp1078_zedboard.zip
I'm trying to run the pre-prepared binary files in the zip file:
xapp1078_zedboarddesignwork_zedboard_14_3zedboard_osl_3_8_kernel_SDcard
The kernel boots OK, but when I run the apps there is no sign of life from CPU1:

I've got two zedboards, neither work.
I also tried the binaries prepared by vcesson (see link), but they fail in the same way.

I guess there are two possible causes of my problem (i) something in my u-boot environment is wrong, or (ii) I have a newer (different) version of zedboard or zynq hardware?
Any ideas?
The output from my kernel booting, and a copy of my u-boot environment is here:

Many thanks, Sam.
