I am currently working on building buildroot for Toradex Verdin iMX8MP SoC. I am trying to build the imx-boot for the same but getting stuck in the build process.
I am following the following article: https://developer.toradex.com/linux-bsp/os-development/build-u-boot-and-linux-kernel-from-source-cod...
One quick question how shall I verify whether my u-boot.bin is u-boot-nodtb.bin?
