Hello, at this moment i'm investigating the possibilities of our current system and would like to know if the 2 Octo-spi peripherals can be used as legacy, normal SPI.

I am using a STM32L4S9 microcontroller and used CubeMX (L4 V1.13.0 Firmware) to generate code for the USB to communicate with the device as a serial port. When sending an exact amount of bytes, 832 to be precise, the data is not send through to the P...

Thanks Andreas, i think this confirms what i was looking for. After testing a bit with the OctoSPI i cannot get it to work as "normal SPI".

Alright, i understand what you were pointing at!I should have given more information.What i need is:Mode = masterData size = 8bitClock polarity = lowClock phase = 1 edgeCRC = offSlave select = software controlfor the transfer i need DMA.I need to tra...

I Did read the documents, but at this point it is not clear if it is possible at all. From DM00366449 it states:3x SPIs (5x SPIs with the dual OctoSPI)but it doesn't make it clear for me if this can also be 5x normal spi, or if the 2x octospi are not...

Hi Kraal,I did not notice the 13 x 64, thanks for pointing this out, thought it was a strange/random number.I tried the same thing with 64 bytes and it does behave the same way. Also when you mention zero length packet, it triggered me to search for ...
