MicroZed PHY timeout

[Richard VanderWal]

Good Morning, 

We are moving our RTEMS 5.1 application on ARM 32 MicroZed hardware (BSP arm/xilinx_zynq_zedboard) to the latest RTEMS master. We have found that the cgem0 interface no longer is initialized and we’re seeing a “phy read timeout: 1” message during boot. This appears to be happening in a call to cgem_miibus_readreg called from cgem_probe. 

We’re running on actual Avnet MicroZed board not anything custom. 

Has anyone else encountered this? Any help is appreciated. 

Thanks in advance!
