Hello，
At present, we want to use the GPMC interface of the SOC to connect to the FPGA. The mode used is address data multiplexing. I checked the relevant information and am currently unsure about the address accessed by the GPMC. Is the address 0x50000000 the access address when using CS0? Or something else? Where can I find it in the manual?
Hello Wanglili,
The CS address 0x50000000 above is the correct one.
The same CS address is mentioned in the TRM as well.
If you use GPMC to connect to FPGA, then you need to configure SOC GPMC as NOR or PSRAM or NAND type.
Already in the 10.1 MCU+SDK version, the PSRAM and NAND support are available.
If you look at the code, there the CS address is also 0x5000 0000.
And, mostly you can go with PSRAM or NOR memory type to interface FPGA.
Regards,
Anil.
