Sterling-60 2230C-P on i.MX 8M Plus using Yocto ST60-2230C-P on i.MX 8M Plus EVK - Yocto Integration This tutorial shows how to get the ST60-2230C-P m.2 board working on the i.MX 8M Plus board using Yocto. Required Items ST60-2230C-P i.MX 8M Plus EVK Linux PC host machine capable of building Yocto and has a Yocto build environment already setup. For help getting the build environment setup review NXP’s i.MX Yocto Project User’s Guide. Setup Set the i.MX 8M Plus board to boot off SD Card Install the ST-2230C-P on the i.MX 8M Plus Power and serial console locations on i.MX 8M Plus EVK Select a release Find the latest Yocto Kirkstone release here: https://source.codeaurora.org/external/imx/imx-manifest/log/?h=imx-linux-kirkstone.

Once the flashing is done and ejected from the PC then install the microSD card into the i.MX 8M Plus EVK and turn on. Connect to the console The i.MX 8M Plus EVK has a USB micro B serial console port when connected to the PC. When the USB micro B cable is connected it will show up as 4 COM ports of which the 3rd COM port in the series ends up being the Linux serial console. Connect to this port at 115200, N, 8, 1 and login as root with no password.
