Hardware overview​

The i.MX8QXP MEK (Multisensory Enablement Kit) is NXP's own evaluation board for the i.MX8QuadXPlus SoC. It has both a microSD slot (J12, USDHC1) and an onboard eMMC (EMMC0); boot source is selected with the SW2 DIP switch on the board.

SD card boot​

SW2 = ON, ON, OFF, OFF (positions 1–4) selects SD card boot — this is the board's default out-of-the-box configuration. Insert the flashed SD card and power on. See the SD card flashing section above for how to write the .wic image.

uuu (USB download to eMMC)​

1. Set boot-mode to Serial Downloader​

SW2 also selects Serial Downloader (USB) mode, but the exact switch positions differ from the table above and aren't reproduced here to avoid giving you a wrong setting — confirm them against NXP's i.MX 8QuadXPlus MEK Board Hardware User's Guide (or the board's Quick Start Guide) before changing switches on real hardware.

2. Connect USB​

Connect a USB cable from the board's USB OTG port to your host PC.

3. Flash​

Using the self-contained bundle (recommended — no uuu install needed):

tar xzf pv-flash-bundle-imx8qxp-b0-mek.tar.gz
cd pv-flash-bundle-imx8qxp-b0-mek
./flash.sh

Or manually, with uuu already installed on the host:

sudo uuu -b emmc_all imx-boot-imx8qxp-b0-mek*.bin pantavisor-starter-imx8qxp-b0-mek*.wic

See the uuu section above for full details and troubleshooting. Unlike the i.MX8M-family boards, i.MX8QXP's ROM uses SDPS: ("stream") serial-download mode rather than plain SDP: — pv-flash-bundle's generated uuu.auto already accounts for this; if you use uuu -b emmc_all manually, uuu picks the right protocol automatically once it detects the board.

4. Restore boot-mode to eMMC​

Set SW2 back to eMMC boot mode (per the Hardware User's Guide) and power-cycle.

Notes​

  • eMMC is USDHC1 (U-Boot mmc dev 0, HS400-capable); the SD slot is USDHC2 (U-Boot mmc dev 1, UHS-capable) — the board ships with SD as the default boot device (CONFIG_SYS_MMC_ENV_DEV=1 in the vendor U-Boot defconfig).
  • This is a bare NXP reference board — no vendor-specific bootcmd hacks are needed for UUU flashing, unlike Toradex.
