Uboot to Linux Display Transition

[danielberhe]

Hi All,

I have managed to display logo in uboot on my custom iMX6 Solo board. The problem I'm having is when Linux starts to boot, the logo disappears and the LCD is just white until Linux finishes initialising the display drivers. I have found this patch but it is quite out of date as it is based on kernel 4.1. Is anyone aware of a patch that would work on later BSPs (4.19 or later)?

Best wishes,

Daniel

you can change the 4.9 according to the old bsp patch, according to the note from patch owner:" no patch for 4.9 and later version kernel, but for debug, you can use "while(1)" dead loop step by step to identify which code modification caused the dsplay disappeared."
