Hi all, I'm working on a Zed-Board whit and embedded linux(ZedBoard_OOB_Design.zip ), but i cant program my FPGA whit my IPcore. My IPcore(Axi4lite memory maped) is just simple and works perfect in stand alone OS. The next thing for me was to create and image boot whit SDK but I'm having some problems when i change the u-boot offset in order to put FPGA .bit. Is there any way to program the FPGA ones the linux all ready boot?
I was searching in the web and there is a char device name xdevcfg to program dynamically the FPGA. like this:
zed$: cat top.bit.bin > /dev/xdevcfg
But my linux image is not having a /dev/xdevcfg device. I notice that the git of digilent and de xilinxs has the xilinxs_devcfg.c in /driver/char/ but is not present in my linux image.
Does anybody try this something like this?
If this is not possible on zed board. Can somebody put a u-bot config in order to put (for ex.) a 4 Mb bit stream to program FPGA? Or just and idea of how to boot a linux and program a FPGA. If im mussing some information or im not clear please let me know.
Thanks a lot for your time and sorry for my bad English :)
PD: I will do the driver to use de IPcore, all i need is to get the linux boot and the FPGA program
