I am facing issue with respect to the Timer controller (TMS320F28335PGFA).
Following are the details,
I have configured the timer (CPUTimer 0) for 312.5us. But while verifying it using Oscilloscope it is observed that it is fluctuating upto 320us - 340us. While analysing the same I observed that whenever I comment the task of updating the data from external memory (SRAM), the fluctuation stops.
The updation task is performed by using memcpy() and comparison using memset() function. I modified it using for loop instead and found it works and timer ticks properly. Kindly let me know if there is any dependency of external memory operation and timer tick interrupt operation.
I am using SRAM interface at Zone7 memory location (0x20 0000). Also I am using DMA Channel 1 for Reading the data from SRAM and Channel 2 for Writing the data to SRAM.The Location for the other SRAM is (0x0004000).
Is there any dependency of DMA operation as well for affecting the Timer tick? since while checking only for Timer tick it works fine and tick is observed upto 313us.
Please find attached files for reference
- CPU Timer initialization routine
- Xintf file
- CMD file for memory allocation

Notes:
Memory blocks on F28335 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.
