Hi Jack, After a little trial and error, this worked for me. I got errors when I left the opb bus the same, and I also tried setting it to opb3, which was not created by an excessive number of yellow blocks. It seems like there has to be a partially full opb bus so it gets created early on in the synthesis process, but it must have room for the DRAM. Then the DRAM must be told to use that partially full bus in the gen_mhs_ip.m file.
I’m running https://github.com/casper-astro/mlib_devel/commits/master from commit d7de268723e20de4523d699c84c8d9e1d6affbc3 on Nov 11, 2016. ( https://github.com/casper-astro/mlib_devel/commit/d7de268723e20de4523d699c84c8d9e1d6affbc3 ) On a side note, I’ve modified startup.m , gen_xps_files.m to let me run in windows 10 and gzip my bof files through 7zip, but neither of those should impact the DRAM. Now I’ve also modified xps_base/XPS_ROACH2_base/core_info.tab and xps_library/@xps_dram/gen_mhs_ip.m where I’ve put the opb_dram_sniffer on the opb1 bus, and I’ve moved the CTRL_C and MEM_C addresses into the 0x02xxx and 0x03xxx regions. I was getting the following error when I changed the addresses but not the opb bus: ERROR:HDLCompiler:874 - "C:/Xilinx/14.7/ISE_DS/EDK/hw/XilinxProcessorIPLib/pcores/opb_v20_v1_10_c/hdl/vhdl/opb_v20.vhd" Line 575: Value 34 is out of target constraint range 1 to 32 ERROR:HDLCompiler:410 - "C:/Xilinx/14.7/ISE_DS/EDK/hw/XilinxProcessorIPLib/pcores/opb_v20_v1_10_c/hdl/vhdl/opb_v20.vhd" Line 576: Expression has 34 elements ; expected 17 ERROR:EDK:546 - Aborting XST flow execution! INFO:EDK:2246 - Refer to C:\roach\Firmware\harvest\ddr\ddr_example11\XPS_ROACH2_base\synthesis\system_ opb0_wrapper_xst.srp for details After both the opb bus and addresses changes, things are working. As far as I can tell I am getting ADC data buffered into the DRAM and then packetized / sent to me over UDP. I’m working on a firmware version that sends counters instead of ADC data to ensure I’m not missing any points. The maximum amount of data I’ve stored in the dram so far is 800,000 counts x 128 bits. Thanks for the timely help! --Adam ---------------------------------------------------- Adam Schoenwald - Electrical Engineer ---------------------------------------------------- From: Jack Hickish [mailto:jackhick...@gmail.com] Sent: Monday, June 26, 2017 3:37 PM To: Schoenwald, Adam J.

Needless to say, I failed. I'm not sure what was wrong, but my spare time to debug got exhausted, and I haven't looked at this since. However, for your particular problem, I think you could just change the DRAM memory addresses, by modifying these two files -- https://github.com/casper-astro/mlib_devel/blob/master/xps_library/%40xps_dram/gen_mhs_ip.m (which sets the address used in HDL, see line 191+) https://github.com/casper-astro/mlib_devel/blob/master/xps_base/XPS_ROACH2_base/core_info.tab (which sets the address that the katcp server will look for the memory, see line 26+). I think as long as the addresses in these two files are consistent, you could change them. Does the dram interface actually work, when you can get the design to compile? If so I'd be interested to know what libraries you're using. Cheers Jack On Mon, 26 Jun 2017 at 12:13 Schoenwald, Adam J.

I also have a 128x2^11 snapshot. I don’t want an interface from the DRAM to the CPU (and have checked the box saying so) if that is relavent. I saw a recent commit by Jack H stating the TX and RX from CPU on 10GBE must be checked, which it is now. I got this to work by deleting software registers, but I don’t think I should have to. Is there any way I can alter the gen_xps_mod_mhs.m file to fix this error? I found I had to keep deleting software registers until I only used the single opb bus (there were some devices added later during synthesis, so with headroom) to avoid getting this error.
