Store Bus Error Cause Mar 22, 2020 16:53:41 GMT Quote Select PostDeselect PostLink to PostBack to Top Post by epistemon on Mar 22, 2020 16:53:41 GMT I'm using ShieldBuddy and HighTec Free toolchain without Arduino IDE. For educational purposes, I want to program a QSPI from scratch.My problem is that a simple register write is causing a "Data Asynchronous Error" of type "Store Bus Error" and I can find no information to understand what I can do to avoid the error.In this simple example, I am just clearing the error flags for QSPI3.QSPI3_FLAGSCLEAR.B.ERRORCLEARS = 0x1FF; /* Clear all error flags. */Searching the Infineon docs just mention the following for "Store Bus Error". There is no further information.• An error on the bus for an external accesses due to a store (Store Bus Error)The DATR (SBE=1) and DEADD (0xF000154) registers confirm that it is my code causing the trap. See pic.I would be very grateful if someone could possibly tell me what might be the cause.Thank you very much.
