Neuron1k: Hi! You might be thinking of the other Joel!

Oh, he already answered :)

_florent_: ping?

mithro: pong

_florent_: I should be asleep, but wanted to show you some stuff quickly if you have a moment

yes I have time

_florent_: https://github.com/enjoy-digital/litex/pull/5

Title: WIP: Add versioning and CI support to litex by mithro · Pull Request #5 · enjoy-digital/litex · GitHub (at github.com)

mithro: cool thanks, I can merge that when you think it's ready

_florent_: The problem is that I didn't really find any "tests" to actually run?

yes we don't have test in litex for now

a good test can be to run the sim target

or generate the hdl for the others targets

_florent_: the problem is the sim target doesn't exit with success/failure in any way

_florent_: does litevideo require litedram? or just for the tests?

_florent_: basically, if you give me some commands to run which exit with non-zero when they fail, I can add it to the CI

_florent_: Here is the litevideo one which is similar -> https://github.com/enjoy-digital/litevideo/pull...

Title: WIP: Add versioning and CI support to litevideo by mithro · Pull Request #4 · enjoy-digital/litevideo · GitHub (at github.com)

yes I have to think how we can get success/failure result from sim target

_florent_: https://travis-ci.org/mithro/litevideo

Title: Travis CI - Test and Deploy Your Code with Confidence (at travis-ci.org)

mithro: I just gived you collaborator access to all the repos (litex, litedram, etc...)

_florent_: yes, I just got like a bazillion emails :P

mithro: feel free to add CI to the repo (if it's not becoming to complex and if we are still able to do manual tests)

_florent_: How should I run the litedram tests? https://github.com/enjoy-digital/litedram/tree/...

Title: litedram/test at master · enjoy-digital/litedram · GitHub (at github.com)

make all, but I still have to add autochecks for these tests

mithro: Got the frequency counter working on base minispartan. I'm adding some code to the firmware to read out the frequency.

_florent_: okay

then I'll start adding HDMI in to the minispartan video target

cr1901_modern: for testing the frequency counter, it should be enough just to add the HDMI EDID Rom on the right pins

cr1901_modern: then the computer will be sending video, you'll just be ignoring it :P

cr1901_modern: but should be able to test if the frequency counter is working

I somehow expect my computer to BSOD when connecting a "monitor" that doesn't exist lol

mithro: for now the tests (in litesata/liteeth) just return the number of errors, but we can adapt that so that CI get the results

_florent_: if you do a sys.exit(number_of_errors) the CI will work

0 == good

non-zero is failure

ok

we can add CI for one of the repo first

cr1901_modern: If you have EDID working the computer won't really know the difference

(litesata for example which has autochecks on all tests)

ahhh alright

and then add CI to all others repos

_florent_: so were are we with upgrading the opsis-soc upgrade stuff?

I'm still doing some work

_florent_: I have a branch prepared with the updated scripts/CI side

I want to clean up things around DRAM

and that makes sense now that I think about it

and I'm adding things on DRAM ports

I need to test that on board

cr1901_modern: obviously I'd love to see working HDMI in and HDMI out working on the miniSpartan6+ :)

then I'll be able to get video in/out working

mithro: the best I could do with the tools I have is frame capture

read the image into SDRAM, then flush to SD card

then on the PC side I could convert the raw image to PNG and you have a very complex screen capture program :D

_florent_: You mentioned you might've solved the bandwidth problems with the minispartan by using a particular HDMI encoding?

The minispartan should have enough bandwidth for 640*480 with any problems

So, start with that :-)

mithro: Sadly, for any of my intents and purposes that's more than enough lmao. An interesting use case for something like minispartan would be a CRT shader for RGB output from old game consoles

cr1901_modern: well, what's stopping you? :-P

mithro: I don't have the correct cables for RGB output from my SNES/

Genesis (if the latter even supports it)

mithro: Point blank, I can think of low-resolution use cases for the minispartan beyond a development board for HDMI2USB. Maybe there can be an "applications" tutorial in the future.

#ifdef XILINX_SPARTAN6_WORKS_AMAZINGLY_WELL ... sarcasm?

mithro: Something like this? http://imgur.com/PfPPgC4

The read bandwidth decreased from 48Mbps tho. Kinda concerning. Also, no write bandwidth lol
