4.2 Expansion Connectors

There are two expansion connectors J1 and J2 (120 pin Samtec connector) for connecting it to Jacinto7 EVM Common processor board. All GESI interfaces, power and control signals are provided with these connectors.

Table 4-1 and Table 4-2 contain the pin out/signal mapping GESI expansion connectors.
