Write to HPS OnChip Memory from FPGA

990 Views

Hey there,

i have initialized an OnChip Memory (dual-port-ram) in the HPS-System with an *.hex file to test if it works.

After that, i have booted Linux and verified the values in the OnChip memory using "devmem.c".

The hex base address from the ram is 00020000 + FFFF0000 (offset) = 00010000.

But the values does not make any sense.

Does anyone know what I'm doing wrong?

In near future, i would like to write values from fpga-side in the memory.

Best regards
