If you want to use our recovery SD card to flash the built U-Boot to NAND flash/eMMC, then copy it to the appropriate location in the SD card: (Replace /dev/sdX with the correct device) $ sudo dd if=imx-boot-sd.bin of=/dev/sdX bs=1K seek=33 conv=fsync U-Boot for the NXP i. $ make -f soc.mak SOC=iMX8MM dtbs="imx8mm-var-dart-customboard.dtb imx8mm-var-som-symphony.dtb " MKIMG=./mkimage_imx8 PAD_IMAGE=./pad_image.sh CC=gcc OUTIMG=imx-boot-sd.bin flash_lpddr4_ddr4_evk arch/arm/dts/imx8mm-var-som-symphony.dtb. arch/arm/dts/imx8mm-var-dart-customboard.dtb. meta-variscite-fslc/recipes-bsp/imx-mkimage/imx-boot/ Root file system As explained in the kernel docs, since Kernel 2.6 release, the main root file system format is the initramfs, which in the different Xilinx workflows is generated as a CPIO file (the name may vary between released images/Petalinux/Yocto flows and it might be compressed as well). $ cp imx-mkimage/iMX8M/*.c imx-mkimage/iMX8M/*.sh imx-mkimage/scripts/*.sh. This is a convenient way of having a single image to. This image combines the SPL with the i.MX header and U-Boot. $ cp firmware-imx-8.8/firmware/ddr/synopsys/*. imx: Add u-boot-with-spl.imx make target. The following procedure builds the final image. The final boot image contains multiple firmware files.

To install the toolchain, follow Yocto Toolchain installation.

4 Install the built U-Boot on an SD cardġ Toolchain installation for out of Yocto builds.

u-boot-imx: U-Boot supported by Freescale u-boot-fslc: U-Boot mainline version.

1 Toolchain installation for out of Yocto builds linux-imx: Linux Kernel supported by Freescale linux-fslc: Linux Kernel.

Load the kernel and DTB according to your preference, and then boot. VAR_SOM_MX6(nand) U-Boot> setenv bootargs console=ttymxc0,115200 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs

Once you've flashed the UBIFS to NAND, set the following bootargs to boot into the UBIFS: Ubiformat /dev/mtd3 -f /path/to/rootfs.ubi -s 2048 -O 2048 Nandwrite -p /dev/mtd1 -s 0x1e0000 /path/to/var_dvk_m圆.dtb Nandwrite -p /dev/mtd1 /path/to/u-boot.img Kobs-ng init -x /path/to/SPL -search_exponent=1 -v You will be operating on /dev/mtd0 thru /dev/mtd3. Variscite i.MX6 NAND partitionīy default, the following partitions exist on the 512MB NAND flash part. These are located at their respective directories in the Factory build_*/images/ directory, or contained within the installed SDK. If you also wish to flash kernel and UBIFS rootfs, copy the kernel uImage, dtb, and rootfs.ubi into your boot media/NFS as well.

Once U-boot has been rebuilt for NAND, you will need to copy the following two files to your SD card, or into your NFS mounted rootfs, so that they can be flashed from userspace: If you have previously built U-boot, you will need to distclean and re-build U-boot by issuing: The default value is: m圆var_som_sd, this needs to be changed to: m圆var_som_nand. Flashing must be done from kernel userspace, and the following packages will need to be enabled to do so:īy default, Timesys provides bootloaders suitable for writing to SD card in order to build U-boot binaries suitable for NAND flash, you need to reconfigure the U-boot config target.

driver Previous message: Shengjiu Wang: PATCH 1/2 ASoC: dt-bindings: imx-hdmi: Add binding doc. The Variscite i.MX6 hardware can boot from either NAND flash or SD card. Mainline U-Boot is limited to be used with Linux 4.
