5.2.12 Local Bus / GPIO connector J22
The COM Express® modules COMe-cP2020 and COMe-bP5020 provide the possibility to connect parallel bus devices (SRAM style)
to their Local Bus. If such interfacing is required please contact Kontron Support for further assistance.
In addition to connecting devices to the Local Bus, the COMe-bP5020 provides twelve GPIOs which are multiplexed within the
Local Bus area. To use these IOs appropriate settings must be selected using the U-Boot SCONF command.
