Hi Experts,
We are using SDK 8.6 in our customer board and we use a LVDS panel which is made by Hanstar. Now we facing a strange issue. Sometimes our boot hangs in the particular time, around 6.9 seconds in kernel. We find this issue happens after we enable the LVDS panel display. Could you give us suggestion of this issue. Thanks. Our kernel log and dtsi setting is below.

display {
compatible = "microtips,13-101hieb0hf0-s";
/*
* Note that the OLDI TX 0 transmits the odd set of pixels
* while the OLDI TX 1 transmits the even set. This is a
* fixed configuration in the IP integration and is not
* changeable. The properties, "dual-lvds-odd-pixels" and
* "dual-lvds-even-pixels" have been used to merely
* identify if a Dual Link configuration is required.
* Swapping them will not make any difference.
