I am following the Jetson Nano Developer Kit 40-Pin Expansion Header Configuration Application Note. Got halfway through and am getting stuck in 5.3. Build U-Boot by running the commands. Issuing the ‘make distclean’ command gives the error: "make: *** No rule to make target ‘distclean’. Stop.
I have successfully done all prior steps in that app note. I have also successfully installed the Jetson Linux Driver Package Toolchain and set the CROSS_COMPILE environment variable. Any ideas?
