Accessing the FPGA Memory space using U-boot

Added by John Mladenik over 13 years ago

I sent this messge to our software guys also but if youcan help it would be appreciated.

In order to debug the FPGA I need the ability to read and write memory locations. I need some help to get this working on my development station.

I have the unit powering up and I can get it into U-Boot utility but every memory location I look at has all zeroes?

What is the memory location of the FPGA? This is whatever CS2 is programmed to.

Will the md (Memory Display) or mw (Memory write) commands access the FPGA memory space? If not is their another way I can poke and peak the FPGA?

thanks

John

Hey I figured it out so never mind. the FPGA is at 0x6000000 and the memory commands in Uboot seem to work.
