Limitation with Pinmuxing

Pinmuxing cannot be made flexible in the example project as the Rx pins of the ports are hard-coded in the default PRU firmware.
Such a limitation shall only apply to 8 RX pins and not to TX and DIR GPIO. To overcome this limitation, a customized PRU firmware should be used by the user.

Configure Maximum number of ports

• In the file iolm_port_smi_example.h, one can set the desired maximum number of ports using the variable IOLM_EXMPL_MAX_PORTS.
  
• After connection is established, the maximum number of ports now seen is 4.
