Vybrid QSPI_MCR offset?

[stephaniegoedec]

I'm looking at the Vybrid-sc QuadSPI_load example.  It has the QSPI_MCR offset at 0x0, but the Vybrid Reference Manual has this offset at 0xf00.  Which offset is correct?  thanks

Hi,

  The RM is incorrect and will be updated in the next version. The MCR register is at offset 0x0.

Hi Stephanie,

The RM should be correct.  In the latest RM, the offset states 0xf00 as well.  Where in the QuadSPI_load example are you seeing the offset of 0x0?  Possibly I have an updated version.

Hope this helps,

Lydia

Hi Lydia,

thanks for checking this.  I'm seeing the offset of 0x0 in the file MVF50GS10MK50.h. This is the reference the DS-5 tools I'm using found for the assignment QuadSPI0->MCR  from the quadspi.c file.  I'll paste the section from the MVF50GS10MK50.h file below.

Our board is a custom board which is based on the TWR-VF65GS10 Schematics (Rev G) schematics.
