Other Parts Discussed in Thread: TMS320C6678
Hi,
I am using TMS320C6678 EVM . I am testing the EMIF16 peripheral,with chip select 3(CE1) with maximum speed configuration
*0x20C00014= (0 \
| (0 << 31) /* selectStrobe */ \
| (0 << 30) /* extWait */ \
| (0x1 << 26) /* */ \
| (0x01 << 20) /* */ \
| (1 << 17) /* writeHold ns */ \
| (0x1 << 13) /* readSetup ns */ \
| (0x01 << 7) /* readStrobe ns */ \
| (1 << 4) /* readHold ns */ \
| (1 << 2) /* turnAround ns */ \
| (1 << 0)); /* asyncSize bus */ \.
According to the datasheet, EMIF16 peripheral uses DSPCLK/6 Frequency as a shared peripheral. i.e,(1000/6=166 MHZ). But In my practical testing analysis after probing the write enable data signal, I am getting 4MHZ approximately which is very much low . Pls check the attached photo images.
Is there any other configuration that i have to make inorder to increase the data frequency .Kindly let me know after checking the configuration and tested images.Thanks, Regards,Thilak
