Hello TI Team,
We are designing our custom board based on TI part number AM6411BSCGHAALV. In our custom design we are using one SDIO interface for WiFi module and other SDIO interface for eMMC.
We are planning to boot the custom board with USB interface with USB host boot mode. we have created partition on USB pen drive similar to the MMC SD card (using create-sdcard.sh) and try to boot the AM642 SK EVM with USB host boot mode and we get below logs.

We required following confirmation from TI.
1) Change we have done to enable USB support in U-boot code is appropriate or not ?
2) we are removing MMC card from hardware design and we are using USB interface for production release flash in blank boards. So Is this USB boot will be continue long term in AM6411BSCGHAALV series of the SoC ?
Please let us know.
