Hi Everyone,
We have made a custom-made Identical to the Zedboard rev C. the only difference is the PHY device. We use National Semiconductor PHY device instead of Marvel.
we cannot get ethernet working.
1. We build the u-boo.elf from the xilinx-u-boot build tree and ran it, it works, however the zynq_gem does not repond. it only reads the PHY device ID and as soon as we ping, the PHY autonegotiation completes but cannot ping the computer connected too. We also built the kernel , but could not boot from JTAG, it just hangs or we get an error which made people migrate to digilent-linux build tree. the kernel simply hangs.
2.we then built the u-boot from digilent and also the the kernel which booted, but neither the uboot.elf or after booting, we can ping or use the ethernet device. we changed the configuration of the kernel to include the NAT SEMI drivers and also the u-boot.elf to use the NATSEMI 83865 . not results at all. even the device tree we changed the drivers from marvel to natsemi, dp83865, but no results at all.
Can anyone help us.... :(
