Xilinx SDK Drivers API Documentation
|
Contains a design example of how to use the low-level macros and functions of the XHwIcap driver.
This example reads back the value stored in the IDCODE register.
This example assumes that there is a UART Device or STDIO Device in the hardware system.
This example can be run on a 7 series device, Zynq device, Ultrascale and ZynqMP Ultrascale FPGAs.
MODIFICATION HISTORY:
Ver Who Date Changes
1.00a bjb 11/21/03 First release 1.00a sv 07/18/05 Minor changes to comply to Doxygen and coding guidelines 1.01a sv 04/10/07 Changes to support V4 2.00a sv 10/10/07 Changes to support V5 4.00a hvm 11/20/09 Added support for V6 and updated with HAL phase 1 modifications 5.00a hvm 02/08/10 Added support for S6 5.00a hvm 04/28/10 Added Check for the control bit clearance in the CR register for regsiter read and write operations. 5.00a hvm 05/04/10 Updated the example to read Id twice so as to igonore the first read. 5.00a hvm 05/21/10 Updated the ID sequence to be consistent across V4/V5/V6 devices. Added an extra NOP before Type1 Read device ID and removed extra NOP after the device ID. This change removed the need of reading ID twice. Removed the extra read ID. 5.01a hvm 07/29/10 Code to check whether read/write bit in control register is cleared after the initiation of respective transfer is added for all devices. This check was earlier done only for S6 devices 6.00a hvm 08/05/11 Added support for K7 family 10.0 bss 6/24/14 Removed support for families older than 7 series 11.0 ms 01/23/17 Added xil_printf statement in main function to ensure that "Successfully ran" and "Failed" strings are available in all examples. This is a fix for CR-965028.
