Demos pins for M4F core
Default M4F pins used by the demos are:
| Function | SoC balls | VAR-SOM-AM62 pins | Symphony pins | Notes |
|---|---|---|---|---|
| UART2 RXD/TXD | R24/R25 | J1.115/J1.171 | J18.9 / J18.7 | The UART2 is not an instance from the MCU domain so only the polling mode is supported. To more details: Accessing main and wakeup domain peripherals from MCU domain Don't use /dev/ttyS2 from linux while running M4F examples to avoid conflicts. |
| MCU_GPIO0_14 (Input) | B3 | J1.155 | J13.16 (HDMI connector) | HDMI to header connector adapter is required |
| MCU_GPIO0_13 (Output) | D6 | J1.157 | J13.18 (HDMI connector) | HDMI to header connector adapter is required |
| MCU_MCAN1 RX/TX | D4/E5 | J1.154/J1.156 | J13.9/J13.11 (TTL levels, CAN transceiver not mounted!) | HDMI to header connector adapter is required |
