Hi community,
I have a question about i.MX6 some interface.
Please see the attached file.
If user repeat read -> write -> read -> write -> ... on the following interfaces, could you let me know the minimum interval between read -> write and write -> read?
GPMI (NAND Fhash)
USB
uSDHC (SD card)

Hi Satoshi
I am afraid it is not possible to answer on that since
internal delays are impossible to predict or calculate.
For example with 8-8-8 DDR and tRALAT =5 one can have
about 50ns @532 MHz just for accessing data from memory.
Latencies caused by OS can be found below
