Hi Jan, Take a look at openembedded-core/build_zedboard/tmp-eglibc/work/zedboard_user_peripheral.../u-boot-xlnx/v2013.../include/configs/zynq_common.h string search for /* Default environment */ After the system boots, I had to make a minor change to the fir filter example. On the ZC702, I was getting a segfault as udev wasn't finding devcfg. /sys/devices/amba.0/ lists f8007000.ps7-dev-cfg, modifying the call to udev_enumerate_add_match_sysname to look for this device instead of f8007000.devcfg and the example now works. Thanks to Jon and company for this work!
