Personal Computer
Board settings
Remove R203, R205-R227 resisters.
Populate R151-R165, R168-R188 with 0ohm resisters.
Remove resistors R2114, R2115, R2118, R2119, R2122, R2123, R2126, R2127, R2130, R2131, R332, R333, to disconnect HyperRAM interface.
Populate these resistors with 0ohm resistor, such as R1329, R2594, R2595, R189-R196, R198, R200-R202, R204.
Remove these resistors, such as R2596, R2597, R228-R235, R238, R240, R242, R244, R246, R248, R250, R252.
Prepare the Demo
Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
When the demo runs successfully, the log would be seen on the OpenSDA terminal like:
