I am running a ZC706 and the FMCOMMS5. I managed to build everything (yes the correct fmcomms5 devicetree) from scratch (following Zynq and the AD9361 and/or AD9364 [Analog Devices Wiki]) install it on a 4GB .img (two partitions) and burned this img to a SDCARD. I also wanted to boot the linaro fs which is put on the ext4 partition. Things boots but then ends out in the ** Unable to read file uramdisk.image.gz **. I can include the uramdisk.image.gz on the boot partition to get a PetaLinux, ie that works (though gives a cut linux mascot in the upper left corner).
But as others, I want to install the linaro from the SDCARD. I think that this can be resolved by supplying an uEnv.txt file to the boot partition. When I do this I get:
Loaded environment from uEnv.txt
Importing environment from SD ...
and depending on what I stick in the uEnv.txt I get different errors. Could you supply an uEnv.txt file ?
