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 <A href="https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Patch-to-support-uboot-logo-keep-from-uboot-to-kernel-for-NXP/ta-p/1120770/page/3/show-comments/true" target="_self">this</A> patch but it is quite out of date as it is based on kernel 4.1.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)?</P><P>Best wishes,</P><P>Daniel</P> Mon, 07 Dec 2020 16:43:01 GMT https://community.nxp.com/t5/i-MX-Processors/Uboot-to-Linux-Display-Transition/m-p/1194852#M166087 danielberhe 2020-12-07T16:43:01Z https://community.nxp.com/t5/i-MX-Processors/Uboot-to-Linux-Display-Transition/m-p/1196164#M166174 <P>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."</P> Wed, 09 Dec 2020 08:25:09 GMT https://community.nxp.com/t5/i-MX-Processors/Uboot-to-Linux-Display-Transition/m-p/1196164#M166174 joanxie 2020-12-09T08:25:09Z
