Hi, our hardware designer connected an SPI device to the SPIFI pins of the LPC4330. The problem is, that we are also using SPIFI, and using it to boot up from flash. I figured out that I can re-mux the pins to SSP in SPI mode after boot up and running code in internal SRAM.  I can then communicate with the other device, which thankfully, I only have to do once to set it up.  After this, I need to then switch back to SPIFI functions.  The problem is that SPIFI code seems to be "gone" at the address range of 0x1400 0000, and no longer accessible. Is there a way to "refresh" the SPIFI?
