The Software Pack named ARM::CMSIS-Driver_Validation contains the following:

Source code of a CMSIS-Driver Validation Suite along with configuration file.
Documentation of the CMSIS-Driver Validation Suite.
Examples that shows the usage of the CMSIS-Driver Validation Suite on various target platforms.

The CMSIS-Driver Validation Suite performs the following tests:

Generic Validation of API function calls
Validation of Configuration Parameters
Validation of Communication with loopback tests
Validation of Communication Parameters such as baudrate
Validation of Event functions

The following CMSIS-Drivers can be tested with the current release:

CAN Interface : with loop back test of communication.
Ethernet Interface : MAC and PHY with loop back test of communication.
I2C Interface : only API and setup; does not test data transfer.
MCI Interface : only API and setup; does not test data transfer.
SPI Interface : with loop back test of communication.
USART Interface : with loop back test of communication.
USB Device Interface : only API and setup; does not test data transfer.
USB Host Interface : only API and setup; does not test data transfer.

The Driver Validation output can printed to a console, output via ITM printf, or output to a memory buffer.

Setup for Loop Back Communication

To perform loop back communication tests it is required to connect the input and the output of the peripherals as shown in this table:

Peripheral	Loop Back Configuration
Ethernet	Connect TX+ (Pin 1) with RX+ (Pin 3), TX- (Pin 2) with RX- (Pin 6)
SPI	Connect MISO to MOSI
USART	Connect TX with RX

The following picture shows the necessary external loop back connections for the Keil MCBSTM32F400 evaluation board:

SPI: PB14 (SPI2_MISO) and PB15 (SPI2_MOSI)
USART: PB6 (USART1_TX) and PB7 (USART1_RX)
Ethernet: Pin 1 (TX+) and Pin 3 (RX+), Pin 2 (TX-) and Pin 6 (RX-)
