SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

recommandation for F427 clocks

Posted by mkrug on 2016-01-14 15:20

Hi,

I’m struggling getting the best out of the clock configurations of the F427 for my needs. I had to use the following peripherals

+ USB FS Device + SDIO-4 wire to connect to a SD Card + ETH RMII Mode (but with external osc) + CAN 500kBit -1MBit + ADC 10kHz + digitial in with Capture Compare with 1µs resolution


For precision reasons I like to use the HSE with 25MHz. This value can be changed if it is of any benefit.

Especially the first two topics makes me some errors. The Cube clock configuration tool was only able to provide a solution for a 120MHz system clock. However I have some demanding algorithms to run and therefore like to be as close as possible at the maximum system clock.

Any suggestions for the different PLL settings?

Best Regards
Markus

Hi,

If you have a USB in the project it will not give the freedom to chose any clock since the USB need excatly 48MHz
But I do not know about CAN + SDIO
I use USB+Ethernet and I could get it at “168Mhz”
