Current U-Boot is an old version and fails to build: /usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here Bump U-Boot to fix the problem. Latest U-Boot has switched to distro boot and SPL, so make the necessary changes to support it. Other advantage of bumping U-Boot is that it also supports the other imx6ul-pico variants. While at it, also bump U-Boot to the 5.15 LTS.

***************************** Technexion i.MX6UL Pico board ***************************** This file documents the Buildroot support for the Technexion i.MX6UL Pico board. Build ===== First, configure Buildroot for the i.MX6UL Pico board: make imx6ulpico_defconfig Build all components: make You will find in output/images/ the following files: - imx6ul-pico-hobbit.dtb - rootfs.ext4 - rootfs.tar - sdcard.img - u-boot.imx - zImage Create a bootable SD card ========================= In the U-Boot prompt lauch: => ums 0 mmc 0 This will mount the eMMC content in the host PC as a mass storage device. To determine the device associated to the eMMC card have a look in the /proc/partitions file: cat /proc/partitions Buildroot prepares a bootable "sdcard.img" image in the output/images/ directory, ready to be dumped on the eMMC card. Launch the following command as root: dd if=output/images/sdcard.img of=/dev/<your-sd-device> *** WARNING! This will destroy all the card content. Use with care! *** For details about the medium image layout, see the definition in board/freescale/common/imx/genimage.cfg.template. Boot the i.MX6UL Pico board ========================= To boot your newly created system: - put a micro USB cable into the Debug USB Port and connect using a terminal emulator at 115200 bps, 8n1; - power on the board.
