Hi,

I'm using Fusesoc on an Altera Cyclone IV FPGA.
I'm trying to implement some decryption process on the FPGA.

Is it possible to access the SDRAM directly via telnet?
(I imagine something similar to the "load_image" command, when writing in the program memory.)

In addition, I want to access the binary I wrote in the SDRAM from a c program (running on the Fusesoc), modify it and write the modified version in the program code.
Can I just use regular c-code to read from the SDRAM? (e.g. "char *p = 0xff73000;" if 0xff73000 was a memory address.)
Will it cause errors if I try to write in the program memory? Is this even possible?


I really don't know how to do this or where I could do some research.

Does anyone know?

Best regards,
Jonathan
