I am trying SDK 3.0.3 example: "can_pal_mpc5744p", it seems some issues on clock_manager, see picture:
1----CAN transceiver usually can use max. 1MHz for communication, but the clock_manager is always 100Mhz, it is gray color, i could not modify the frequency.
2----LIN bus max 20k bit/s as per industrial standard, but here for LIN0/LIN1 port it is always 100Mhz and not allowed to modify.
3----the listed prescale factors are not enough to lower down peripheral clock frequency, some external devices are usually low speed which needs MCU clock to be low , not so high in the clock_manager
should I look forward to next version of S32DS ?
Hello @bingwang312,
I'm afraid that you had a misunderstanding: What you're mentioning are the clock sources for peripherals, which are configured by clock_manager regarding the clock tree as per Reference Manual, and they are NOT the baudrate frequencies outside the buses. If you want to change the baudrate frequencies, you shall need to look into each module, e.g for CAN:
