Introduction
The CL-SOM-AM57x firmware consists of two components: Secondary Program Loader (SPL) and U-Boot, provided as binary images: MLO and u-boot.img. This article describes the firmware update process for CL-SOM-AM57x system-on-module product.
Preliminary setup
- Make sure to power off the CL-SOM-AM57x evaluation platform.
- Connect the host PC to the SB-SOM base-board (connector P8) via the serial cable supplied with the evaluation kit.
- On your computer, start a terminal emulation program (such as HyperTerminal) with the following serial port settings:
Baud Rate Data Bits Stop Bits Parity Flow Control 115200 8 1 none none
- Turn on the CL-SOM-AM57x evaluation system. The U-Boot boot-loader will start and you will get a command prompt in the terminal window.
If the boot settings of your CL-SOM-AM57x are different than default, you may need to press and hold ^C while turning the CL-SOM-AM57x on, in order to get command prompt. |
Updating Firmware on the internal SPI flash
CL-SOM-AM57x firmware can be updated from an SD card, USB storage, or using network TFTP download. All methods are performed from the U-Boot command line and include following common steps:
- Loading binary images from the selected media to the CL-SOM-AM57x SDRAM
- Flashing images to the on-board SPI flash
Updating from TFTP server
- Setup a TFTP server
- Put the firmware binary image cl-som-am57x-firmware in the root directory of the TFTP server
- Setup U-Boot networking:
- for dynamic IP configuration:
# dhcp
- or for static IP configuration:
# setenv ipaddr <ip address>
- Setup the TFTP server ip address:
# setenv serverip <server ip>
- Load the SPL and U-Boot binaries into the memory:
# tftp 82000000 cl-som-am57x-firmware
- Proceed to Flashing images section
Updating from SD Card / USB storage / mSATA drive
Copy the firmware binary image cl-som-am57x-firmware from U-Boot package for CL-SOM-AM57x to the root directory of the respective media.
Updating from SD card
- Insert the SD card into the P9 socket on SB-SOM.
- Start the U-Boot MMC subsystem:
# mmc dev 0 # mmc rescan
- Check that the storage device is ready:
# ls mmc 0
- Load the firmware binaries into the memory:
# load mmc 0 82000000 cl-som-am57x-firmware
- Proceed to Flashing images section
Updating from USB storage
- Plug the USB storage device into the USB host connector (P3) on SB-SOM.
- Start the U-Boot USB subsystem:
# usb reset
- Check that the storage device is ready:
# ls usb 0
- Load the firmware binaries into the memory:
# load usb 0 82000000 cl-som-am57x-firmware
- Proceed to Flashing images section
Flashing images
- Probe the SPI flash:
# sf probe
- Write the firmware image into the on-board SPI flash:
sf update 82000000 0 C0000
- Reset the CL-SOM-AM57x evaluation platform.
