Driver Validation

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:

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-)
