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

You are right. Unfortunately there isn’t any LPC driver for MQX. So, you have to write your own or you can pay for that.
In first case I would like to recommend one of our older application note AN3902 How to Develop I/O Drivers for MQX:
