Hi All:

 

One of my customer is testing DDR3 and Nand filesystem r/w speed based on TWR-VF65GS10, below is test sample code.

The test result is not aligned with spec,

(1)

For DDR3 test, only 250Mbit/s is observed. actually should 800MHz datarate

(2)for Nand filesystem, run demo from MQX FSLMQXOS_4_0_2_FFS.exe

the read datarate is 1.21Mbytes/s, write rate is only 0.85Mbytes/s
