In our system, two Flashs are connected to SS0 and SS1 of ECSPI1 port.
And ECSPI Boot from SS0 is used.
We have a problem that boot fail occurs infrequently.
W6 pin is used as ECSPI1_SS1.
This W6 pin is GPIO Input 100K pull-up by default.
We checked SS pins of ECSPI.
We found that SS1 became Low at SS0 assertion.
We think that internal Pull-up is not enabled.
Is the description of the data sheet right?
Is there the method that this pin sets to the High(Pull-up) during ECSPI Boot?
May I have advice?
