2.9 SPI Test There are two SPI interfaces on MY-RK3288-EK314. 2.9.1 Interface Properties The test requires the use of the MISO and MOSI pins of the SPI interface, which are listed in the table below.
1) Use SPI self-transmission (output) and self-reception (input). Note: The test requires short-circuiting the pins of the evaluation board. If you are not sure that you can short-circuit correctly, please ask the hardware engineer for support, otherwise the evaluation board may be damaged.
2) The SPI interface that matches the SPI test program is SPI2, so our SPI test is to test SPI2. 2.9.3 Test method 1) Prepare for the test by short-circuiting the MISO and MOSI pins of SPI0. 2) Execute test # ./spi_test -D /dev/spidev0.0 3) Test result If SPI is normal, you will see the following characters on the terminal: FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF DE AD BE EF BA AD F0 0D
