A lot of u-boots I've found point to a ramdisk filesystem instead of a partition. >> >> The images here include a u-boot.elf that works with Zedboard, ZC702, >> ZC706, etc. >> http://wiki.analog.com/resources/tools-software/linux-software/zynq_im >> ages >> >> Email me directly and I'll just send you the .elf if you're interested. >A pox on people using ancient stuff. >I think Sean wants to load an fpga image early in the boot process. Not trying to do anything fancy; just trying to reproduce Jonathan Pendlum's FFT filter example, which was written back when that ancient stuff was current. I think it'd be good for that to be updated for people who want to run GNU Radio on Zynq. I know RFNoC will change how that's done with E310, but we don't need RFNoC for MicroZed/ZedBoard/ZC70x.
