• conf_example.h example configuration

Device Info

All AVR XMEGA devices can be used. This example have been tested with the following setup:

• Xplain * - XMEGA A1 Xplained
• XMEGA-A3BU Xplained

Description of the example

The example tests the flash and reports back the status on the Xplain/A1 Xplained LEDs:

• LED0: Atomic erase and write of application table section works as expected
• LED1: Write without erase of application table section works as expected
• LED2: Atomic erase and write of boot section works as expected
• LED3: Write without erase of boot section works as expected
• LED7: Test completed

In the case of the A3BU Xplained:

• LED0: Atomic erase and write of application table section works as expected
• LED1: Write without erase of application table section works as expected
• LED2 (Red): Atomic erase and write of boot section works as expected
• LED3 (Green): Write without erase of boot section works as expected
• LCD Backlight: Test completed (Successful tests on LED2 and LED3 will appear as an orange color)

If one of the LEDs does not light up, this indicates a failure on the test.

Dependencies
