QUADSPI boot initialization sequence

[pelegk]

hello,

in my application, i will use the LS1023 MPU.

I would like to use the QUADSPI boot initialization, which means that in Power on, the image will be taken from NOR flash in QSPI.

in chapter 4.4.5.1 note 2, is written that Booting from QSPI takes precedence , when mentioned QSPI A.

my question is, if QuadSPI boot initialization sequence demends QSPI A only, or can i use the QSPI B.

if its possible to boot from QSPI B, my next question is how the MPU knows from which channel to take the image.

your advise please

The note is about pin multiplexing and means that mentioned QSPI signals' functions will be configured forcibly if QuadSPI is selected as RCW source.

Booting is possible only from QSPI_A.
