Hello All,Ran the test that Chris provided "time python ex_icestick.py" on 2 Ubuntu 12.04(2 core & 6 core AMD) and Pi 2B built w/yocto. GCC needed to be upgraded to 4.9 from 4.6 to compile the tools. This site provides and explanation on how to upgrade. http://charette.no-ip.com:81/programming/2011-12-24_GCCv47/ | Yocto Pi 2B | | | | | | real | 0m20.943s | | user | 0m12.210s | | sys | 0m0.500s | | | | | Ubuntu 2 core | | | real | 0m5.310s | | user | 0m1.865s | | sys | 0m0.197s | | | | | Ubuntu 6 core | | | | | | real | 0m3.956s | | user | 0m1.093s | | sys | 0m0.120s | Dave completed the layout of the ICE-40 board a few days ago. - Lattice iCE40-HX8K FPGA in 256-pin BGA. - 32 MByte SDRAM (16M x 16). - Serial configuration flash (at least 2 Mbit). - Three Grove connectors. - Two PMOD connectors. - One 20x2 header with 3.3V, ground and 18 FPGA I/Os. - Two SATA headers (for differential signals; don't know if they would work with SATA HDDs.) - DIP switch with four SPST switches. - Two momentary pushbuttons. - Four LEDs. - 32 KByte HAT EEPROM. - 40-pin RPi GPIO header. Excited to test. Let me know if you have any questions.Cheers Edward Vidal Jr. e-mail dev...@sb... 915-595-1613 On Tuesday, September 15, 2015 7:11 AM, Edward Vidal <dev...@sb...> wrote: Chris,Test results myhdl 15 sec yosys 11 sec The resulting files are located at https://github.com/develone/raspberrypi2_yocto.git The folder benchmark_yosys contains the file bench_mark_yosys.txt the steps I used and the files generated on RaspBerry Pi 2B. It also has the iceiver folder. Note chmod +x iceriver/icestick.sh to make it work. Now need to compare the generated files that you got on Ubuntu.Let me if that is what you wanted. I do not have a board to test the bin file.Regards Edward Vidal Jr. e-mail dev...@sb... 915-595-1613 On Monday, September 14, 2015 10:28 PM, Christopher Felton <chr...@gm...> wrote: On 9/14/15 2:32 PM, Edward Vidal wrote: > Hi Chris, I added code to compute the shasum and now the make test is > running longer.

I don't have an R2 (or 1) to test but the following is an example starting with a myhdl file, generating a bitstream for an icestick using the open-source tools [1]. I built this into some automation stuff I have used in the past. Running the example on my old'sh ubuntu system I get: >> time python ex_icestick.py real 0m3.6s The above converts the simple myhdl file, then runs the yosys/arachne/icestorm to generate the bitstream. I don't have an icestick so I couldn't test it.
