The i.MX8M family of processors can boot from multiple sources: eMMC, SD card, etc. Our board lacks an SD card slot so this method can be discarded right off the bat. Although booting from eMMC is possible, it would require us to overwrite its persistent storage with a disk image every single time. We will do this at some point in the following sessions but for now the most convenient solution is using SDP to download flash.bin via a serial connection, over USB.

In order to select Serial Download as the preferred method of boot, you will need to set two jumpers on the board. Find J1 and J2 and configure them according to the figure below.
