From 6cda4f68619ec139be7897ea61b7f22c72c38b59 Mon Sep 17 00:00:00 2001 From: Vladimir Vid Date: Mon, 9 Jul 2018 11:09:53 +0200 Subject: imx6: Initial support for SolidRun CuBox-i devices based on i.MX6 processors (i1, i2, i2eX, and i4Pro). - Specifications - CuBox i1: - SoC: i.MX6 Solo - Cores: 1 - Memory Size: 512MB - GPU: GC880 - Wifi/Bluetooth: Optional - USB 2.0 ports: 2 - Ethernet: 10/100/1000 Mbps CuBox i2 | i2eX: - SoC: i.MX6 Dual Lite - Cores: 2 - Memory Size: 1GB - GPU: GC2000 - Wifi/Bluetooth: Optional - USB 2.0 ports: 2 - Ethernet: 10/100/1000 Mbps CuBox i4Pro | i4x4: - SoC: i.MX6 Quad - Cores: 4 - Memory Size: 2/4 GB - GPU: GC2000 - Wifi/Bluetooth: Build In - USB 2.0 ports: 2 - Ethernet: 10/100/1000 Mbps Built-in u-boot requires SPL (secondary program loader) to be present on the SD-card regardless of the image type which will be loaded. SPL is generated by the u-boot-mx6cuboxi package which is preselected by the target device and can be found in bin/u-boot-mx6cuboxi directory. Flashing the SPL: dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=4 dd if=bin/targets/imx6/generic/u-boot-mx6cuboxi/SPL of=/dev/mmcblk0 bs=1K seek=1 Preparing the firmware on the SD-card: (echo o; echo n; echo p; echo 1; echo ''; echo ''; echo w) | fdisk /dev/mmcblk0 mkfs.ext4 /dev/mmcblk0p1 mount /dev/mmcblk0p1 /mnt tar -xzf bin/targets/imx6/generic/openwrt-imx6-device-cubox-i-rootfs.tar.gz -C /mnt/ mkdir -p /mnt/boot cp bin/targets/imx6/generic/{*-uImage,*.dtb,*.scr} /mnt/boot/ Generated u-boot.img needs to be placed on the first partition: cp bin/targets/imx6/generic/u-boot-mx6cuboxi/u-boot.img /mnt/ To boot from the SD card: Boot script which sets mmc/dtb parameters and boots the board is automatically sourced. If this does not work for any reason: mmc dev 0; load mmc 0:1 $scriptaddr boot/boot.scr; source $scriptaddr Currently imx6dl-cubox-i.dtb (Dual Lite) and imx6q-cubox-i.dtb (Quad) device trees are available. Tested on i4Pro, MMC, USB (+ HiD), HDMI and ethernet ports are working. Wireless and bluetooth are broken ATM. According to SolidRun forums, BCM4329/BCM4330 firmware is used which works fine on older kernels.
