In my setup, I have connected a QSPI NAND flash (IS37SML01G1) to the OSPI1 interface.When I configure OSPI1 in 1-line SPI mode, I can write a specific data pattern to the NAND flash and read it back for comparison without encountering any issues.Belo...

Hi @KDJEM.1 ,The command CLK doesn't really bother me since I have no isuse to send command and get correct response in single SPI mode on Octo-SPI interface.I tried different memory types to transfer data in QSPI mode but it doesn't work.That's why...

Hi @KDJEM.1 ,I have succesfully accessed ISSI NAND memory in single SPI mode on OSPI interface. Commands and data are transmitted in single SPI mode without issue. (You are right. It doesn't make sense to transmit 8bits command in 7 SCK. Maybe the I...

Hey @KDJEM.1 ,Not so sure about "command necessities 7 clock"?Data is transmitted in 4-lines (QSPI) mode. All the command / addresss are transmitted in 1-line mode.

I tried both settings - HAL_OSPI_MEMTYPE_MACRONIX and HAL_OSPI_MEMTYPE_MICRON. None of them work on QSPI mode.

Hi @ame MCU Support Center BB , My case is kind of tricky that the memory (ISSI S37SML01G1) only supports Quad SPI. I am managing connect a QSPI memory to STM32's OSPI port. Not sure which memory type I should select.
