How to use NXP's LPC546x and MFR4310 to realize FlexRay? need help.

[geweilin]

I'm using LPC546x and now want to add FlexRay interface to my board. So I think we can use EMC module with MFR4310 and TJA1080 as a solution.

But I have no idea how to achieve it. Expect someone can provide help from two aspects of hardware schematic diagram and software implementation method.

Hi, Weilin,

Regarding your question, first of all, I would like to remind you of the fact that the LPC546xx operating temperature range is from -40 °C to +105 °C, it does not meet the automotive quality standard, as far as I know that the Flexray is used in auto application. The MPC56xx/57xx, S32K are auto level processor.

Anyway, I think it is okay to use EMC module to access the MFR4310 as a SRAM with AMI(Asynchronous Memory Interface) mode, the LPC546xx provide the signals: address bus, data bus, control bus(/CS,/OE,/WR,BLS0/1).

Hope it can help you
