We also use&nbsp;the fsl_can.c/h driver provided with the MCUXpresso SDK 2.5.0. In the two examples provided in the SDK:</P><P>- boards\lpcxpresso54628\driver_examples\mcan\interrupt_transfer</P><P>- boards\lpcxpresso54628\driver_examples\mcan\loopback\</P><P>the fsl_mcan.c function MCAN_SetMsgRAMBase() is called with the MSG_RAM_BASE address fixed to 0x20010000 i.e. beginning of SRAM1.</P><P>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?</P><P>Is there a limitation where the base RAM address can be placed to the CAN driver?</P><P>Where is this limitation described?</P><P></P><P>Many thanks</P><P></P><P>Dani</P></BODY></HTML> Fri, 01 Feb 2019 09:18:41 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-fixed-RAM-address-0x2001000-for-CAN/m-p/878305#M35127 danielgull 2019-02-01T09:18:41Z Re: LPC546xx fixed RAM address 0x2001000 for CAN https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-fixed-RAM-address-0x2001000-for-CAN/m-p/878306#M35128 <HTML><HEAD></HEAD><BODY><P>Daniel,</P><P>have a look here:&nbsp;<A href="https://community.nxp.com/message/964791">https://community.nxp.com/message/964791</A>&nbsp;</P></BODY></HTML> Fri, 01 Feb 2019 13:21:46 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-fixed-RAM-address-0x2001000-for-CAN/m-p/878306#M35128 carstengroen 2019-02-01T13:21:46Z
