AM2434: MCAN baud rate

Hi Nancy,

Please see this e2e FAQ for a description of how MCAN data rates are calculated: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/920090/faq-tda4vm-can-how-is-bit-rate-calculated-for-can. The calculations in this thread apply to AM243x.

See the AM243x TRM for more information on the MCAN registers: https://www.ti.com/lit/ug/spruim2c/spruim2c.pdf

There are several MCAN examples in MCU+ SDK, please see:

• https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_03_00_18/exports/docs/api_guide_am243x/EXAMPLES_DRIVERS_MCAN_EXTERNAL_LOOPBACK_INTERRUPT.html
• https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_03_00_18/exports/docs/api_guide_am243x/EXAMPLES_DRIVERS_MCAN_LOOPBACK_INTERRUPT.html
• https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_03_00_18/exports/docs/api_guide_am243x/EXAMPLES_DRIVERS_MCAN_LOOPBACK_POLLING.html

You can experiment with any of these to better understand how to set the baud rate.
