Using QSPI1 as normal SPI MC56F84786

20Sidar04 — Thu, 02 Nov 2023 07:47:07 GMT

Dear Mr. and Mrs.,

I have a board with MC56F84786 NXP microcontroller. This MCU is connected with Flash memory via SPI. In addition to this, Flash has QSPI pins but in this design, QSPI pins are not used. Instead of QSPI pins, SPI pins are used. I saw configuration for QSPI on IDE. I couldn’t see config for SPI. QSPI1 could be used as standard SPI . Is Library of QSPI1 valid for SPI. How should be config for SPI by using QSPI1 on Codewarrior?

Thanks in advance for supports.

Regards.

Sidar

Hi,

The spi of MC56F84786 is called queued spi instead of quad spi. The QSPI of MC56F84xxx is a normal spi interface,it can interface with 4 pins spi flash, the 4 pins includes sck, /cs, mosi and miso.

Obviously, it can not interface with quad spi flash.

Hope it can help you
