I would like to communicate between two F28069 via CAN bus.

Are there any example or document for using ECAN on F28069?

Please download my Application report http://www.ti.com/lit/spra876. It has many tested examples. I also urge you to look at the Debug tips provided.

The TRM chapter explains the CAN protocol implementation in the MCU. i.e. it explains the function of registers/bits. However, it does not explain the protocol itself. For that, excellent resources are available online (Search YouTube for Controller Area Network)

Here is a list of available CAN books:

Note that the app.note examples were written for the TMS320F28335 device. However, they can be easily adopted for any 28x device with eCAN, provided you take care of the change in SYSCLKOUT speed and the resultant changes warranted for the CANBTC register.
