FDCAN bit timings incorrectly calculated

[maxschommer]

In the following section the FDCAN settings are laid out and a nominal and data rates of 500kbps and 2Mbps are calculated.

stm32-mw-openbl/Interfaces/Patterns/FDCAN/fdcan_interface.c

Line 54 in 7689c2d

fdcan_ker_ck | 20 MHz | 20 MHz

I plugged in those settings into CubeIDE for the H523, and got 250kpbs and 1Mbps calculated. I'm biased to trust the CubeIDE calculation because it agrees with the AN2606 Table 115 which lists FDCAN settings as 250kbps and 1Mbps.

Hi @maxschommer,

This is a typo in the comment of the template.

The values are like the ones described in AN2606:

• 250kbps for connection phase
• 1Mbps for data phase

Best regards,
Aymen.
