From some initial research, there may be a conflict unpacking .7z files on OS-X. I tried creating images in 3 different ways, with the native unzip as described on the Nvidia imaging page, with the Unarchiver, and with a homebrew install of 7zip. The JetsonNano.7z unpacks into a .img file (which is required for both Imager and Etcher, as neither support .7z), and after several attempts in various ways (using both imager, etcher, and cmd line instructions ) the same thing happens at every boot attempt, as follows:
[ 1.177435] tegradc tegradc.1: dpd enable lookup fail:-19

ls shows standard directories and in the /dev/ folder shows mmcblk0 through mmcblk0p9
This image was procured from Qengineering
Is there a mounting procedure that can correct this from here?
