linux crash after PL load

Former Member
Former Member over 9 years ago

I have made a simple hardware design for the PL. I can load it with either JTAG or by cat'ing the file into xdevcfg. Once the hardware is loaded, it functions properly. Howver, all contact with the PS (running Linux) is gone. No terminal, no ethernet. Is it not possible to just load a bit file with no reference to the processor? Looking in the UCF there doesn't appear to be any reference to any processor specific IOs. I'm guessing that I need to route some PS dedicated pins to some specific hardware pins, but I would have thought that could be done without anything loaded into the PL at all. Any insight would be appreciated.

    Hi jeffallred, I have tried to design a simple IPcore and use it in Linux. "FSBL.elf" can load your hardware bitstream to PL. Then, your hardware must have a AXI interface and connect it to the internal AXI interface of PS.All this can be finished in Xilinx Platform Studio(XPS). http://wiki.xilinx.com/zc702-boot-from-flash  this website maybe helpful.
    PS. I really no good at English.Sorry for the grammar mistake :)

    You say "your hardware must have a AXI interface". Is this a documented requirement? Is Linux polling the AXI or does the lack of an AXI interface in the PL cause an interrupt?

    It seems very dangerous to the system if loading the PL with a design that doesn't include a particular interface causes the OS to crash.

    Hi jeffallred,You must have read this document, "Zynq-7000 EPP Technical Reference Manual". In the page 32,it's to said 'there are two type of interfaces between the PL and the PS'.One is functional interfaces, the other is configuration signals. I don't know how do you connect your hardware design to PS, but if you don't use any functional interface, it's dangerous I think. My IPcore make by XPS works well, and Linux device driver works well too. It never causes the OS to crash.
    PS. If you haven't read the document you can search it in www.xilinx.com. 
    If you think I can help you, is welcome to sent me a message for e-mail.
