PetaLinux 2013.10 - Zynq Design With Only Ethernet GEM1 Fails To Build


My system includes only Zynq GEM1 for Ethernet. 

During the petalinux-build operation, my build fails with the following messages in <PLNX_PROJ>/build/build.log:

[ALL  ] board.c: In function 'board_eth_init':
[ALL  ] board.c:144:7: error: 'CONFIG_ZYNQ_GEM_PHY_ADDR1' undeclared (first use in this function)

This is caused by incorrect logic in the <PLNX_PROJ>/build/linux/u-boot/petalinux-auto-board.h.template file.  

The logic in this file is not creating a constant called CONFIG_ZYNQ_GEM_PHY_ADDR1

This can be resolved by putting the following line in the <PLNX_PROJ>/subsystems/linux/configs/u-boot/petalinux-user-config.h.template file :


<ADDR> should be set to the MDIO PHY address for the PHY in your system.  

Most Xilinx evaluation platforms default to a value of 7. 

If this is the only Ethernet interface in your system you can also try a value of 0.
