Tue Jan 11 08:55:41 CET 2022
The EVM architecture for J721S2 is similar to that of J721E and J7200. It
is as follows,
+------------------------------------------------------+
| +-------------------------------------------+ |
| | | |
| | Add-on Card 1 Options | |
| | | |
| +-------------------------------------------+ |
| |
| |
| +-------------------+ |
| | | |
| | SOM | |
| +--------------+ | | |
| | | | | |
| | Add-on | +-------------------+ |
| | Card 2 | | Power Supply
| | Options | | |
| | | | |
| +--------------+ | <---
+------------------------------------------------------+
Common Processor Board
Common Processor board is the baseboard that contains most of the actual
connectors, power supply etc. The System on Module (SoM) is plugged on to
the common processor baord. Therefore, add support for peripherals brought
out in the common processor board.
