PN7462 Stack Issue

[mukadder]

Why local variables in a SPIM R/W function ( access to / from a NOR flash ) fails read / write to SPIM bus.

However, Accessing to/from NOR flash using global variables with the same SPIM R/W function results with no error.

What can be the problem? By the way, the project uses no RTOS.

Regards.

Looks like a software issue, is the optimization too high? Please try a lower level and check if it works.

Hope that helps,

Have a great day,
Kan
