I'm trying to bring up a custom board with iMX8M mini processor with 32bit LPDDR4 RAM, Where i'm able to bring up the uboot using SDP mode by setting boot in Serial Download and trying to use boot linux kernel using uuu script. Here i'm trying to to use RAMDISK in kernel so no need to flash emmc.
while trying to bring up USB on USB1 i'm getting No USB device found USB init failed: -19 Here i've attached all my changes. If anyone point me to specific area where to troubleshoot further. We have removed type c port from code as we are not using the one.
I'm using u-boot from branch lf_v2022.04 and kernel from branch lf-5.15.71-2.2.0.
UUU script
uuu_version 1.5.165
# Please Replace below items with actually file names
# @_flash.bin | boot loader

Got solution
Who ever want to port u-boot for custom board consider board-u-boot.dtsi file u-boot consider this file without mentioning in Makefile.
Below is the link which describe the functionality of xxx-u-boot.dtsi.
