Hi, 

I am trying to run Dhrystone on Cortex R52x2 (MPS3 board) QSPI memory. 

For both cache enable or disable, I am getting same values .

cached - 499356305 ticks 

uncached - 499356241 ticks

can someone please explain why is it happening ? For BRAM and TCM it's working fine. 

or is there any option to specifically Turn ON cache for QSPI mem ???
