xc7-litex failing

[scted]

failing in travis.ci

pre-req is fixissue 65 to get tests running

progress so far fixing is that the litex stuff is being installed outside of the symbiflow-examples directory so a cd needs to happen ... see line 5

i would prefer if the install instructions gave the user a measure control on where all the Litex stuff ends up ... needs a $LITEX_INSTALL_DIR

with the cd fix, the test is now failing in litex/litex/build/xilinx/symbiflow.py", line 103, in ####_run_make

Indeed this seems to fail on ubuntu:trusty and old centos but not on other OSes? (other OSes have travis timeouts but that is much later in the run)

[scted]

[edited for clarity] i only tested it on Ubuntu:focal and it was failing ... will retry with new .travis.yml on my fork

[scted]

still not passing ubuntu:focal fwiw

erroring out for the directory issue:

i assume it will fail later in symbiflow.py line 103 (see above for Traceback) which is

if tools.subprocess_call_filtered(shell + [script], common.colors) != 0:

i can't find reference to 'shell', 'script' or 'common' anywhere in symbiflow.py

Hi @scted, this issue has been solved in litex upstream, and the error should not appear anymore if you get the latest litex version (I think you can do ./litex_setup.py update install to get the latest)

@acomodi

i still can't get it to complete in Travis (see bottom for Traceback) ... now failing line 84 ... apologies if it is usererror on my part

tools.subprocess.py not returning 0 ... way beyond my capability to troubleshoot

still had to modify the xc7/README.rst to cd up one level to get this to get this far

@scted I think that we resolved all the problems here (according to https://github.com/SymbiFlow/symbiflow-examples/pull/73#issuecomment-734935737) and we can close this issue. Is that true?

[scted]

thanks

@rw1nkler FYI, there is a discrepancy between the Litex arty platform and the new migen arty_a7 platform ... was using that because i am using migen to build my own stuff ... the migen stuff almost works but it says the device is 'xc7a35tic324-1L' ... symbiflow was failing at step 8 of synth ... i changed the device to 'xc7a35tic324-1' and everything worked ... not sure where to report that ... lot of new migen stuff

@scted Thank you for reporting this! This is a good place to report any problem with the SymbiFlow Toolchain. I would suggest opening a separate issue for that, to track the problem. (This issue is closed) In fact, I probably know what is causing the problem. Can you please open a separate issue with the information that you gave above? Can you also provide more detailed information on how to reproduce your problem?
