Blinky demo BSP
- Blink state is shown through target board LED2 on P0[22].
- Tracing info through UART0_TXD assigned to P0[2] on J6.21 connector at 38400 8N1. To interface the demo board with Trazer PC software, you may use the simple circuit shown below to convert UART0_TXD signal to RS232 levels.
