Forum Post: RE: Actual GPMC XIP Timing on EVM is different from TRM.

Biser-san, Jeff-san,
Thank you so much for your strong support.
Sorry for my late reply.

The requirement is following:

a) GPMC clock cycle is specified as 50MHz on TRM.
   But, actually the clock cycle is 100MHz.(GPMCFCLKDIVIDER=0h)

b) Actually, TIMEPARAGRANULARITY=1h
   But, its register field value is not specified on TRM.

c) Instead, if you specifies the XIP Timing Parameters using clock cycles, tCSEXTRADELAY must be "1/4".
   Because the one clock cycle is specified 20nsec and actually the delay is 5nsec ("1/4").

My important customer has strong requirement to fix above.
So I need approval to fix it from TRM team.
Can you get the approval from TRM team?

Best regards, RY
