QSPI Slave configuration in i.MXRT 1170

[neetha_jyothish]

I want to use two i.MXRT 1170 boards, one configured as QSPI master and the other as QSPI slave. I have the following two questions:

1.Is it possible to configure QSPI (Half duplex 4-bit mode) as Slave in i.MXRT 1170? I have referred the following link, but I could not find any information about configuring as QSPI slave.

https://community.nxp.com/t5/i-MX-Processors/QSPI-on-i-MX-RT-1170/m-p/1764319#M216423

2. Is there any difference in the QSPI communication of a flash device and a non-flash device? For example, if we are trying to interface a QSPI slave that is not a flash device, are there any additional configurations/commands that must be used?

I am planning to communicate two i.MXRT 1170 over QSPI. Let me know any care to be taken in hardware or software ??

Hi @neetha_jyothish ,

The FlexIO can be used to simulate a SPI slave device, please kindly refer to driver_examples\flexio\spi for details.

 a QSPI flash device usually complies with JESD specs, while a non-flash device has no such kind of requirement.

Have a great day,
Kan

Configuring QSPI as a slave might not be a standard feature, and it seems like the link you provided doesn't have information on it. You might need to consult the official documentation or the NXP community for specific guidance. Regarding QSPI communication, the requirements can vary between flash and non-flash devices. It's essential to refer to the datasheets and documentation of the QSPI slave you're using, as they might have different protocols or commands.
