The psu_init is not writing the correct value to that register to change it to the EMIO clock.

This needs to be set in xfsl_hooks as follows:

XFsbl_Out32(0xFF180308, XFsbl_In32(0xFF180308) | 0x21);

Replace the xfsbl_hooks.c file in {PROJECT_PATH}/components/bootloader/zynqmp_fsbl/ with the version attached to this Answer record.

This patch will update the GEM clock control register in the IOU SLCR to change GEM 0 and 1 to be EMIO clocked for RX.

Rebuild the PetaLinux project and package the BOOT.bin.

{PROJECT_PATH}$ petalinux-build
{PROJECT_PATH}$ petalinux-package --boot --format BIN --fsbl images/linux/zynqmp_fsbl.elf --fpga images/linux/zcu102_hpc0_qgige_wrapper.bit --u-boot images/linux/u-boot.elf --force
