Looking at the include/config_distro_bootcmd.h and in particular at CONFIG_CMD_USB I don't see BOOTENV_RUN_PCI_ENUM listed. It is listed for NVMe, VirtIO, DHCP stuff. In other words the current code in bootcmd does not expect USB to be connected via PCIe. Thus I suggest adding BOOTENV_RUN_PCI_ENUM (one line) to CONFIG_CMD_USB config as in other boot options. That seems to be the correct approach. david > CONFIG_DISTRO_DEFAULTS=y > CONFIG_FIT=y > CONFIG_SPL_LOAD_FIT_ADDRESS=0x84000000 > -- > 2.32.0 >
