iMX6SL Loading Kernel Issues

Question asked by Yakov Shaulov on Jan 25, 2017

Hello,

We are currently stacked at Kernel Loading stage.
We're modified the Device Tree Struct file regarding the HW peripheral on our board.
So when we try to load the modified Kernel to RAM we met some errors/fails or uncleared messages (as shown on kernel log from the terminal).
Here is a list of all errors (please find attached file with the kernel log: mfgtool_kernel_log_20170125.txt):
line 105: imx6sl-pinctrl 20e0000.iomuxc: Invalid fsl,pins property in node /soc/aips-bus@02000000/iomuxc@020e0000/imx6sl-wizcom/hoggrp

line 210: : switch to mmc0 failed
line 217: imx_usb 2184000.usb: Can't register ci_hdrc platform device, err=-517

We tried to re-modify and to follow the code branches in order to solve those issues, but it's too complicated and we cant came to the right results.
We also expected our board turn to "Mass Storage Device" but it doesn't happened.
Our board includes PF3000 PMIC, 1GB LPDDR2, 4GB eMMC v5.0, Audio Codec, 8-bit CSI Camera, SPI LCD, Battery Charger and Fuel Gauge.
Can you please check the Kernel log file, describe the mentioned lines and explain us what can be the source of this issues?

Appreciate your support,
Jacob
