WB TEST¶

The program is designed to test the operation of the module with the FPGA project WISHBONE.

Features¶

• Display information BAR0 - list of control units
• Display information BAR1 - list of control units TEST_CHECK, TEST_GENERATE
• Checking of the data input from the TEST_GENERATE
• Checking of the data output to the TEST_CHECK
• Synchronous data input from the TEST_GENERATE and data output to the TEST_CHECK
• The calculation of the current exchange rate - in the interval 4 seconds
• Calculating the average exchange rate - with the launch of
• Error logging

Source code¶

The source code of the program is in the repository: trunk/soft/linux/application/wb_test

Catalogs:

• bin - executable and configuration files
• src - source code

Catalog src

• Makefile - for build
• work - source code

The program uses the files in the directory trunk/soft/linux/common/

• pex - contains class files: pex_board
• utils - contains useful files

Starting the program¶

Before starting the program you want to load driver pexdrv.
To load the driver script is used insert from the directory soft/linux/driver
Loading the driver: sudo ./Insert.
Unloading Driver: sudo rmmod pexdrv

To view a list of available devices can run the command ls /dev/AMB *
The device name is formed as follows: /dev/<device name> <sequencenumber of the device>
For example: /dev/AMBPEX50

Launch:
./wb_test <device name> <configuration file> [<configuration file>]

• <device name> - logical device name, for example /dev/pexdrv0 (not currently implemented, is always used pexdrv0)
• <configuration file> - cfg file with parameters

List of configuration files:

• test_gen.cfg - inputs from the TEST_GENERATE
• out_check.cfg - output to the TEST_CHECK

If given two file that runs two of the testing process, if only one file is only one testing process.
