Dear,
We would on the STM32H7B0RBTx connecting 2 external QSPI RAM of APS6404L-3SQN-SN.
Therefore we will use the 2 QSPI RAM chips in Multiplex mode, but we have only 1 NCS pin that we can configure.
When we look in the application note AN5050 on page 27 we see that it is possible but with STM32Cube it isn't possible to configure the NCS pin on port 2.
What we doing wrong here?
How we should configure the other parameters of the QCTOSPI in STM32cube for the used RAM chip?
OCTOSPI1
OCTOSPI2:
The OCTOSPIM_P2_NCS pin is PG12 which isn't available on the LQFP64 package.
STM32H7B0RBTx is an LQFP64 package, rather small, so it has a limited number of pins. You'll have to move up to a larger package, at least the LQFP144, if you want to do this.
