issues with memwrite and memread
Posted: Dear Eli,
I've included a seekable RAM interface in my xillybus core along with the streaming interface. The xillybus_mem_8 device is 32 samples deep and 32 bits wide. I checked that the device exists in /dev list. When I do a hex dump, I'm able to see that all the 32 locations have a value of 0 initialized (as expected). But when I use the following command for memwrite:
sudo ./memwrite /dev/xillybus_mem_8 0 1; followed by
sudo ./memread /dev/xillybus_mem_8 0
I see the output is Read from address 0: 0.
Also, when i give the address argument more than 1, in both memwrite/memread, it says "Failed to Seek: Invalid Argument".
Kindly advice !
Thank you,
Mugundhan
