i am using Cortex-r4f now，and i feel confused about how to use BTCM and ATCM port ， is there some reference files about the detail of TCM interface timing.
Depends on the SoC. In general, the SoC's manual describe the timing.
do you have the link of Soc's manual and pages number of relative describion.
As I do not know which chip you are using, how can I?
i use tms570ls3137
So what does the manual tell you. Or do you want others to read it for you?
Cortex-R4 and Cortex-R4F Technical Reference Manual (arm.com) this document have description of tcm interface
but detail interface timing isn't available 。so is there any
other document that i can learn tcm interface timing
How about the data sheet of the SoC?
no relative description too
Then have you contacted the chip manufacturer for support?
not yet，do you have datasheet of tcm interface timing
