| + | {{:Transclusion: CL-SOM-iMX7: U-Boot: Firmware Update}} |
| − | The CL-SOM-iMX7 firmware consists of single U-Boot binary image {{filename|cl-som-imx7-firmware}}.
| |
| − | This article describes the firmware update process for CL-SOM-iMX7 system-on-module product.
| |
| − | | |
| − | == Preliminary setup ==
| |
| − | * Make sure to power off the CL-SOM-iMX7 evaluation platform.
| |
| − | * Connect the host PC to the SBC-iMX7 base-board (connector P8) via the serial cable supplied with the evaluation kit.
| |
| − | * Start terminal emulation software on your PC with the following serial port settings:
| |
| − | <blockquote>
| |
| − | {{:SB-SOM: serial port parameters table}} | |
| − | </blockquote>
| |
| − | * Turn on the CL-SOM-iMX7 evaluation system. The U-Boot boot-loader will start and a command prompt will be displayed.
| |
| − | *: {{Note|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.}}

| − | == Updating Firmware on the SPI flash ==
| |
| − | CL-SOM-iMX7 firmware can be updated from an SD card, USB storage, or using network TFTP download.
| |
| − | Both methods are performed from the U-Boot command line and include following common steps:
| |
| − | # Loading binary image from the selected media to the CL-SOM-iMX7 DRAM
| |
| − | # Flashing image to the on-board SPI flash
| |
| − | | |
| − | === Common preparation steps ===
| |
| − | * Reset the U-Boot environment to default state:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # env default -a
| |
| − | </pre>
| |
| − | * Clean up the address space in order to allow the SPI flash burn with a fixed size:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # setenv ubootsize 0x80000; mw.b ${loadaddr} 0 ${ubootsize}
| |
| − | </pre>
| |
| − | | |
| − | === Updating from SD card ===
| |
| − | * Copy the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.com/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] to the root directory of the SD card.
| |
| − | * Insert the MMC/SD card into the SD socket (P9) on the SBC-iMX7.
| |
| − | * Start the U-Boot MMC subsystem:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # mmc dev 0
| |
| − | CL-SOM-iMX7 # mmc rescan
| |
| − | </pre>
| |
| − | * Check that the storage device is ready:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # ls mmc 0
| |
| − | </pre>
| |
| − | * Load the firmware binary into the memory:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # load mmc 0 ${loadaddr} cl-som-imx7-firmware
| |
| − | </pre>
| |
| − | * Proceed to [[#Flashing images|Flashing images]] section
| |
| − | | |
| − | === Updating from USB storage ===
| |
| − | * Copy the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.com/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] to the root directory of the USB storage device.
| |
| − | * Plug the USB storage to either port on the dual USB host connector P6 of the SBC-iMX7.
| |
| − | * Start the U-Boot USB subsystem:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # usb start
| |
| − | </pre>
| |
| − | * Check that the storage device is ready:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # ls usb 0
| |
| − | </pre>
| |
| − | * Load the firmware binary into the memory:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # load usb 0 ${loadaddr} cl-som-imx7-firmware
| |
| − | </pre>
| |
| − | * Proceed to [[#Flashing images|Flashing images]] section
| |
| − | | |
| − | === Updating from TFTP server ===
| |
| − | * Setup a TFTP server
| |
| − | * Put the firmware binary image {{filename|cl-som-imx7-firmware}} from [http://www.compulab.com/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/#devres U-Boot package for CL-SOM-iMX7] in the root directory of the TFTP server
| |
| − | * Setup U-Boot networking:
| |
| − | : for dynamic IP configuration:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # dhcp
| |
| − | </pre>
| |
| − | : or for static IP configuration:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # setenv ipaddr <ip address>
| |
| − | </pre>
| |
| − | * Setup the TFTP server ip address:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # setenv serverip <server ip>
| |
| − | </pre>
| |
| − | * Download the firmware binary into the memory:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # tftpboot ${loadaddr} cl-som-imx7-firmware
| |
| − | </pre>
| |
| − | * Proceed to [[#Flashing images|Flashing images]] section
| |
| − | | |
| − | === Flashing images ===
| |
| − | * Make U-Boot probe the on-board SPI flash:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # sf probe
| |
| − | </pre>
| |
| − | * Erase the on-board SPI flash:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # sf erase 0 ${ubootsize}
| |
| − | </pre>
| |
| − | * Write the firmware image into the on-board SPI flash:
| |
| − | <pre>
| |
| − | CL-SOM-iMX7 # sf write ${loadaddr} 0x400 ${ubootsize}
| |
| − | </pre>
| |
| − | * Reset the CL-SOM-iMX7 evaluation platform.
