For A10 AS configuration time

hi, we are using 10AS016E4 on our boards, and use the EPCQ-L(MT25QU01G) for AS configuration.

Below is the setting for the configuration.

For my device, the rbf file is 11466204 byte, with 100Mhz config clock, so I estimate the config time is about 11466204X10ns=115ms, but per my test, the actual time from power on to user mode is more than 1s. 

so my qeustion:

1. what's wrong for my estimation method?

2. why the actual config time is so long?

3. how to reduce the config time?

 

thank you.

Hello,
configuration speed in ASx1 mode is 1 bit per clock cycle, your calculation misses factor 8.

If the AS flash interface is wired for ASx4, you should select ASx4 configuration scheme. Also enable compression in programming file generation when using .jic files.
