The following documentation provides a quick guide to boot from USB OTG port.
1. Clone a repository to install and build imx_usb_loader application by run the follwoing:
git clone https://github.com/boundarydevices/imx_usb_loader.git cd imx_usb_loader make |
imx_usb_loader : This application implements the Serial Download Protocol that the i.MX6 Boot-ROM uses to communicate. It is available on github account of boundarydevices.
The final binary is called imx_usb and can be executed in place.
2. Install SPL & U-Boot binaries:
wget https://solid-run-images.sos-de-fra-1.exo.io/IMX6/U-Boot/v2018.01/spl-imx6-sdhc.bin wget https://solid-run-images.sos-de-fra-1.exo.io/IMX6/U-Boot/v2018.01/u-boot-imx6-sdhc.img |
You can Install U-Boot & SPL binaries from SolidRun Images site.
3. Serial connection
Please see our pages Cubox-i, HummingBoard Edge under serial connection section.
4. Connect your Male to Male USB-A cable to the OTG port on your device.
Identify the OTG portTo quote our developer Jon: “it is the top port next to the Ethernet jack” More formally it is the top port on the U5 header. This holds true of all our i.MX6 based boards. |
Make sure you can detect the USB = NXP Semiconductors in the usb devices list with the exact same vendor ID as shown in the following example:
5. Run the script imx_usb exec with the SPL to load SPL:
sudo ./imx_usb spl-imx6-sdhc.bin |
On success, SPL should announce itself on the serial console:
6. Run the script imx_usb exec with the U-Boot to load U-Boot :
sudo ./imx_usb u-boot-imx6-sdhc.img |
On success, U-Boot should announce itself on the serial console:
Success Indicator for Cubox-i |
At this point U-Boot has been loaded to RAM and is running.
