    104104The methods you use to update the firmware depends on what specifically you are trying to update.
    105105
     106Be care to use firmware images built for the specific SOC on the board you are using. Venice boards use a variety of IMX8M SoC's which have different boot firmware:
     107||= Board =||= SoC =||= Notes =||
     108|| GW710x-0x-* || i.MX8M Mini (aka IMX8MM) || use firmware with 'imx8mm' in the name ||
     109|| GW720x-0x-* || i.MX8M Mini (aka IMX8MM) || use firmware with 'imx8mm' in the name ||
     110|| GW730x-0x-* || i.MX8M Mini (aka IMX8MM) || use firmware with 'imx8mm' in the name ||
     111|| GW740x-*    || i.MX8M Plus (aka IMX8MP) || use firmware with 'imx8mp' in the name ||
     112
     113You can tell what you are using by watching the board boot:

     117CPU:   Freescale i.MX8MP[8] rev1.1 1600 MHz (running at 1200 MHz)

     123}}}
     124 - The above CPU banner shows 'i.MX8MP' which requires firmware with a 'imx8mp' in its name
     125 - The latest firmware images set the 'soc' U-Boot env variable to match the SoC you are using
