Tool/software:
Hi,
There are two FD CAN channels for AWR2944 chip，in the AWR2944 Technical Reference Manual, in the chapter 12 CANFD ,there are details as below:
2.1.1 Features
The MCAN module implements the following features:
• Conforms with ISO 11898-1:2015
• Full CAN FD support (up to 64 data bytes)
• AUTOSAR and SAE J1939 support
• Up to 32 dedicated Transmit Buffers
• Configurable Transmit FIFO, up to 32 elements
• Configurable Transmit Queue, up to 32 elements
• Configurable Transmit Event FIFO, up to 32 elements
• Up to 64 dedicated Receive Buffers
• Two configurable Receive FIFOs, up to 64 elements each
• Up to 128 filter elements
• Internal Loopback mode for self-test
• Maskable interrupts, two interrupt lines
• Two clock domains (CAN clock/Host clock)
• Parity/ECC support - Message RAM single error correction and double error detection (SECDED) mechanism
• Local power-down and wakeup support
• Timestamp Counter
• Full Message Memory capacity (4352 words).
I have a question about this. There are 64 dedicated Receive Buffers, the 64 dedicated Receive Buffers are shared by the two FD CAN channels or every FDCAN channel has its own 64 dedicated Receive Buffers?
Thanks.
