The firmware can be updated from an SD card, USB storage, or using network TFTP download.Īll methods are performed from the U-Boot command line and include following common steps: Copy the contents of you bootfs folder, which contains kernel, device tree and auxiliary binaries to the tftp directory: sudo cp -Ppr /path to bootfs/ /srv/tftp/. If the boot settings of your CL-SOM-iMX7 are different than the default, you may need to press and hold Ctrl-C while turning the CL-SOM-iMX7 on, in order to get command prompt. Therefore, for this example, the board will be set to SD. For this example, U-Boot and all other images are loaded from the SD card. U-Boot can fetch images from different memory sources such as eMMC, SATA, TFTP, SD, and QSPI. The U-Boot boot-loader will start and a command prompt will be displayed. After FSBL, the U-Boot configures the rest of the peripherals in the processing system based on board configuration. ![]() Turn on the CL-SOM-iMX7 evaluation system. bootp - boot image via network using BOOTP/TFTP protocol bootvx - Boot vxWorks from an ELF image bootz - boot Linux zImage image from memory bubt - bubt - Burn an image on the Boot flash device. ![]()
