I am using Halcogen to generate LLD for TMS570LS0914. But it seems like there are only 64 Message Objects for each CAN channel.

Q1. How to transmit/receive more than 64 CAN messages on single CAN channel?

Q2. Is there any example code for the same? If yes, please share

Q1. How to transmit/receive more than 64 CAN messages on single CAN channel?

The idea is to use a combination of identifier and mask bits to configure the channels to your needs.

enter image description here
Source: TMS570LS09x/07x Technical Reference Manual , page 1236

For very high priority messages you could set all mask bits to match one specific message identifier. And for low priority messages you would set the mask bits to allow a large range of message identifiers.

For more information see SPNA131.

Q2. Is there any example code for the same?

TI provides HALCoGen to generate HAL code for the TMS570.
