Boot Linux operating system from a USB or NVMe drive

You can boot up the Qualcomm Dragonwing™ RB3 Gen 2 Core Kit (QCS6490) either using an NVMe SSD, or a USB mass-storage device attached. Connect the flashed NVMe drive onto the Industrial Kit M.2 slot, or the USB drive onto the Type-C port.

Kernel configuration

USB and NVMe boot support requires the following kernel configurations to be enabled:

CONFIG_REGULATOR_QCOM_PM8008=y
CONFIG_REGULATOR_QCOM_USB_VBUS=y
CONFIG_USB_XHCI_PCI_RENESAS=y
CONFIG_USB_RENESAS_USBHS_HCD=y
CONFIG_USB_RENESAS_USBHS=y
CONFIG_USB_CONFIGFS=y
CONFIG_USB_MASS_STORAGE=y
CONFIG_RENESAS_USB_DMAC=y
CONFIG_PHY_QCOM_USB_HS=y
CONFIG_PHY_QCOM_USB_SNPS_FEMTO_V2=y
CONFIG_PHY_QCOM_USB_HS_28NM=y
CONFIG_PHY_QCOM_USB_SS=y
CONFIG_QCOM_GPI_DMA=y
CONFIG_I2C_QCOM_GENI=y
CONFIG_USB_ONBOARD_DEV=y

The Renesas USB3 host controller requires renesas_usb_fw.mem, a firmware file distributed by Renesas, to be packed into the initramfs under the /usr/lib/firmware path. These configurations can be added to meta-qcom/recipes-kernel/linux/linux-qcom-6.18/configs/bsp-additions.cfg.

Prepare and boot from a USB or NVMe drive

Preparing and using the USB or NVMe drive as fallback boot media follows the same steps as Boot Linux operating system from the SD card, using the USB or NVMe device node (for example, /dev/sda or /dev/nvme0n1) in place of the SD card device node.
