Hi
We are using the CAN interface on the LPC54628. We also use the fsl_can.c/h driver provided with the MCUXpresso SDK 2.5.0. In the two examples provided in the SDK:
- boards\lpcxpresso54628\driver_examples\mcan\interrupt_transfer
- boards\lpcxpresso54628\driver_examples\mcan\loopback\
the fsl_mcan.c function MCAN_SetMsgRAMBase() is called with the MSG_RAM_BASE address fixed to 0x20010000 i.e. beginning of SRAM1.
We tried to move this base address to beginning of SRAM2 i.e. MSG_RAM_BASE = 0x20018000. With this modification the example does not work. Why?
Is there a limitation where the base RAM address can be placed to the CAN driver?
Where is this limitation described?
Many thanks
Dani
