imx8mp-a0-nitrogen8mp.dtb not found #69

Closed bwhitman closed 2 years ago

Hi I have a nitrogen8mp board, rev 2020-10-08. I am using the Yocto HOWTO here: https://boundarydevices.com/yocto-hardknott-release-for-i-mx8-platforms/

The board does not boot, saying it cannot find "imx8mp-a0-nitrogen8mp.dtb" in the U-boot console. This is nowhere in the yocto build files. Instead, there is a imx8mp-nitrogen8mp.dtb . If I rename the DTB the board continues to boot but pauses after the line

And eventually reboots. Any idea how to get this rev of board working for yocto hardknott?

Hi, Yes the A0 support has been removed after the first release as NXP dropped its support after the last beta release. The A0 was a pre-production silicon only meant for early adopters. We recommend getting a production version of the SOM in order to use any of the latest SW. Please reach out to info@boundarydevices.com for more info.
