Help on using DMA to access  External memory interface (LPC) of MPC5125

Hi,

     I have a requirement to access the memory on an FPGA interfaced to the external bus(LPC) of MPC5125 processor. The memory access has a high data rate, so a DMA access is required. The driver for LPC interface and DMA driver are not available with MQX RTOS. 3.8 (last version for MPC5125). How to start with developing a driver for using the LPC interface together with DMA?

 

Thanks for help in advance
