2016.2 PetaLinux Zynq UltraScale+ MPSoC GEM Clock Control needs to set for EMIO clock for RX

描述

This Answer Record covers how to update the GEM clock control register in the IOU SLCR to change GEM 0 and 1 to be EMIO clocked for RX.

解决方案

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
