CyUSB Serial DVK test utility for I2C/SPI
================================================================================
This utility is used for testing I2C/SPI master mode functionality on the
Cypress CyUSBSerial DVK.
The utility writes to I2C/SPI flash devices on the DVK, reads the data back
and verifies the data read for integrity.
Release components:
================================================================================
1. Test_Utility.c ==> Source file of the command line test utility
2. 90-cyusb.rules ==> udev rules for changing the mode of usb device node.
3. CyUSBSerial.sh ==> Script file for implementing hotplug feature in linux.
4. Makefile ==> make file for compiling and installing the application.
================================================================================
Pre-requisites:
================================================================================
1. libusb-1.0.9 is required for compilation and functioning of the APIs in the
USB Serial library.
2. The CyUSBSerial library (libcyusbserial.so) should be compiled and installed
on the test machine.
3. GNU Make and the GCC tool-chain are used for the build process.
================================================================================
Installation steps:
================================================================================
1. Change to the folder where the utility source files are extracted.
2. Invoke 'make' to build compile the utility, and to install the configuration
files at the appropriate locations. This should be done from a super-user
(sudo) shell, because the configuration files need to be copied into system
folders (/usr/local/bin).
3. Use the CyUSBSerial command to start the test utility.
Note:
The udev daemon needs to be restarted to reflect the udev rule changes that
are installed as part of the make command.
================================================================================
Using the test utility:
================================================================================
1. On starting the utility, the Cypress USB Serial devices that are connected
are listed along with their device numbers, interface numbers and
functionalities (SPI or I2C).
$ CyUSBSerial
----------------------------------------------------------------------
Device Number | VID | PID | INTERFACE NUMBER | FUNCTIONALITY
----------------------------------------------------------------------
0 |4b4 |a | 0 | VENDOR_I2C
0 |4b4 |a | 1 | VENDOR_SPI
0 |4b4 |a | 2 | NA
----------------------------------------------------------------------
2. A menu providing the various operations is also printed:
----------------------------------------------------------------------
1: Print list of devices
2: Select device...No device selected !!
3: Enter I2C/SPI Flash page address and length to write/read.
4: Verify data
5: Exit
----------------------------------------------------------------------
3. On selecting option 2, the utility prompts for the device and interface
number to be selected for testing.
-----------------------------------
Enter Device number to select:
0
Enter interface number:
1
-----------------------------------
Once the selections are made, the menu will be updated with the details.
----------------------------------------------------------------------
1: Print list of devices
2: Change device selection--selected device: [Device number 0] : [Interface No 1] : SPI
3: Enter I2C/SPI Flash page address and length to write/read.
4: Verify data
5: Exit
----------------------------------------------------------------------
4. Option 3 can be selected now to do data read/write to the I2C/SPI flash
device. The utility prompts for the page address to be written as well as
the length of data to be written.
------------------------------------------------
Enter Page address ... (less than 65536)
1234
Enter length to read/write ... (less than 256)
32
------------------------------------------------
Length needs to be less than or equal to 256 bytes in the case of SPI access,
and less than or equal to 64 bytes in the case of I2C access. Page address
needs to be less than 65536 in case of SPI and 256 in case of I2C.
Once the values are selected, the menu is updated with the details as below:
-------------------------------------------------------------------
1: Print list of devices
2: Change device selection--selected device: [Device number 0] : [Interface No 1] : SPI
3: Change Flash page address and length ...Entered is page address 1234 and length 123
4: Verify data
5: Exit
-------------------------------------------------------------------
5. Selecting option 4 causes the utility to write a randomly generated data
sequence to the flash device, read it back, and verify the data read back.
The data pattern written and read back will be displayed as shown below:
--------------------------------------------------------------------
67 c6 69 73 51 ff 4a ec 29 cd ba ab f2 fb e3 46 7c c2 54 f8 1b e8 e7 8d 76 5a 2e 63 33 9f c9 9a
--------------------------------------------------------------------
Data Read back is:
---------------------------------------------------------------------
67 c6 69 73 51 ff 4a ec 29 cd ba ab f2 fb e3 46 7c c2 54 f8 1b e8 e7 8d 76 5a 2e 63 33 9f c9 9a
---------------------------------------------------------------------
Data verified successfully
-------------------------------------------------------------------
6. The utility runs through these menu options until the user selects the
exit option (5).
7. If a new Cypress USB Serial device is attached or an existing device is
removed while the utility is running, a notification is printed on the
console.
---------------------------------------
Device of interest Removed/Added
---------------------------------------
