UART I2C and SPI Tests

Hello All,

I have drafted test plan for verifying peripheral behavior but Does
anyone have system level tests for testing i2c, uart and spi
peripherals from a software perspective? pls share the tests that one
should carry out for thoroughly verifying a driver from:
1. i2c multimaster
2. i2c slave mode
TX and Rx functions.

regards
bala

Many kinds of tests can be done.
You may need to do the following
1) Read data from a Control Register of a particular slave device
2) Write data to a Control Register of a particular slave device
3) In the case of UART try configuring for different baudrate
settings.
    Have a loopback test also.
4) Normally you may need to check if all the status registers and
   control registers can be 'read from'/'written to' properly.
5) In the case of SPI, check the different Chip Selects.
