mithroxobs: Develop or flash? You mention "The starting filesystem size is limited to 768 MB, to let users use smaller SD cards." ?06:36
xobsmithro: ideally either. I'm looking into what it would take to put nextpnr, icestorm, yosys, and a riscv compiler on there.06:40
xobsThe 768 MB change was because I have some 1GB cards here, and it doesn't make sense to require a 4 GB card when most of the space is empty anyway.06:40
mithroxobs: <- It kind of looks like conda has RPi support...06:40

mithroewen: Did you get to micropython booting on the tinyfpga-bx in the end?07:15
mithroxobs: I was also pondering the stuff nrossi did to recreate the litex-buildenv using yocto stuff...07:16
*** TheAssassin has quit IRC07:16
mithroxobs: That lets you produce "sdk"s07:16
xobsmithro: it's been forever since I've used yocto [openembedded]. The hardest bit is getting a RISC-V cross compiler. The second hardest thing is integrating nextpnr which requires qt5.07:18
mithroxobs: Just don't build with the gui07:18
mithroThat is my solution :-P07:18
xobsAh, okay. I thought python support required the gui. But I guess it's the other way around!07:19

mithroewen: I'm not sure why that isn't being rendered properly...07:25
ewenmithro: Review done.  There was one fatal error (at least on Python 3.6 it seems to be throwing a different exception than you expected on the common path), and three instances of formatting string confusion, plus a possible wrong exception catch (I'm a bit unclear on the exception heirachy at that point; see GitHub pull request comments).07:45
ewenmithro: (... catching up) Yes, I did get MicroPython booting on TinyFGPA BX.  I can program the TinyFPGA BX with the MicroPython included image, and get serial console.  But I still can't program with the non-MicroPython image (H2U?).  (As best I can tell it's failing due to a short read at a consistent point while verifying, but I'm unclear why it's a short read and whether it's just accidentally working07:49
ewenin practice and needs a loop to retry the read.)07:50
ewenmithro: Re rendering, it looks like it's assuming that it's text, not Markdown, and showing it raw.  I'm unclear why. suggests that PyPI should support GitHub flavoured Markdown...07:52

ewenmithro: AFAICT the commits are still merged into tinyfpga master (eg, I can pull them from there).  So I'll just test against that.  (I don't seem to be able to fetch from the pull request any more now it's closed.)08:41

mithroewen: Yes, I push is with a merge commit however08:44
*** puck_ has quit IRC08:46
ewenmithro: re issues/18, looks like that ValueError would be *after* it'd been through the try:/except:, as it's a ValueError on int() getting an empty string.  Rather than the bit you changed which was exception handling of ord()....08:50
mithroewen: Yeah08:50

ewenmithro: I think the PyPI formatting confusion is being caused by trying to use a multi-line Summary: (description=... in, which is resulting in a stray blank line in PKG-INFO, which is causing everything after that to be treated as description not headers.22:04
ewenmithro: In which case adding .strip() to the end of the multi-line string setting description= should fix it.22:05
ewenHmm, there's also an embedded newline that'll need to be removed.  I'll figure out a more detailed approach and make a pull request.22:19
