intel_onchip_memory II RAM no W/R from FPGA but from HPS

Hi guys,

I try to write and read to/from a intel_onChip Memory 2 RAM.
But it only sets the first or the last byte in the RAM to 0x00 depending on how high I set the ram_addr_reg.

I am using a Arria10 SOC Development Kit.

The initial file is transferred well with all data on the right spot.

And I can read and write the RAM from the C-Program on the Linux HPS.

But i then try to write something from the FPGA only the first Byte changes to 0x00.
This I can overwrite by the C-Programm again.

I can do this procedure as often as I want.


Do you see any mistake I've made in my code or the setup?

Please see code and pic attached.

Thanx,

Linus
