TX2 PCIe clock issue

Hi, Using Busybox devmem command, I managed to read back and write the registers. I tried the following : read back of register T_PCIE2_PADS_REFCLK_BIAS (address 0x100030D0) with 0x28, this is the recommended setting from the Tuning Guide read back of register T_PCIE2_PADS_REFCLK_CFG0_0(address 0x100030C8) with 0x80B880B8 read back of register T_PCIE2_PADS_REFCLK_CFG0_1(address 0x100030CC) with 0x000480B8 I have a oscilloscope to measure 1 of the 3 PCIe reference clock on my Printed Circuit B…

regards,
