Sorry for the long response about this. I just want to confirm for future readers that this works with this commit.

Why you do not have a plan?is it hard to port an RTOS?

I don't know how hard is it to port.
But I will not do it because I don't need it.
Why do you need it?

For easily managing timings I lately used this simple tasker: https://github.com/joysfera/arduino-tasker

oh..I see, thanks, maybe time can tell.

Hi there guys,
Is there any available or ported RTOS for STM32F407VE using stevstrong's core?
Thank you.

Thanks. I will update you as soon as I have my board again

Anyway, this topic is linked to use it with @stevestrong core for F4, if I'm not wrong?

yes it is @stevestrong core

This is my working example for your reference.
No modification in the SPI ot SDFat library is needed.

SD card read/write

This example shows how to read and write data to and from an SD card file
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11
** MISO - pin 12 ...

Hi,
I got it working now in different SPI port without commenting the last few line in the SPI.h.

What I did is i place "SPI_3.setModule(3);" before the initialization of sd2.begin.

SPI_3.setModule(3);


I saw this ".setModule()" in the Ethernet_STM32 example and tried in the sd example.

Thank ...

Hi @TFTLCDCyg , I tried your suggestion but the response is the same...failed to initialize the sd card.
