GPMC Timing analysis

Other Parts Discussed in Thread: AM4377

hi all..

I'm new to this timing analysis for GPMC interface.

i have very basic doubts. Could someone help me.

The GPMC interface (clock freq - 100MHz) is from AM4377 ARM processor to ASIC - NOR flash, asynchronous, non-multiplexed mode.

In the datasheet for AM4377 i could find 3 tables showing internal timing parameters, timing requirements, switching characteristics.

which one should i follow in order to verify the timing.
How to start with checking the timing characteristics for the layout.
what are all the parameters to be taken into count during READ and WRITE timing check.

  • Hi,

    In your case you should refer to section 5.12.8.1.2 GPMC and NOR Flash - Asynchronous Mode. You should also read through section 9.1 of the AM437X Technical Reference Manual Rev. C, where you will find detailed information on GPMC functionality and programming.
