How to change PE clock in CAN config

[kbj]

I want to set CAN bit rate to 5Mbps.

But at PE clock 8MHz, max bit rate that I can set is 1Mbps.

So I want to change PE clock, but I don't find how to change PE clock.

Please let me know how to change PE clock.

Hello,

use flexcan module instead of can_pal module. Flexcan module allows to set PE Clock in processor expert. See the figures below:

Hi,

Thanks for your help.

I changed PE clock to 48MHz.

But at 48MHz PE clock, Maximum CAN FD bitrate is 4.8Mbps.

I can not set over 5Mbps.

I want to set over 5Mbps.

How to set 5Mbps CAN FD?

Beat regards,

Byungju.
