<trabucayre> pepijndevos: pff new limitation with gowin: compressed bitstream ...
<trabucayre> and, of course, my license is out of date :(
<daveshah> I'd lol if it used the same compression algorithm as ECP5
<trabucayre> For my specific problematic it's not the algo but lines with different length...
<trabucayre> But maybe I need to reread ECP5 format to find a more clever way to implement fs parser :)
<daveshah> You're right, it doesn't affect programming really
<pepijndevos> do people actually use compressed bitstreams?
<daveshah> yes - faster load/boot times, less flash used
<daveshah> since I added --compress to ecppack it's been very popular, there's little reason not to use it
<daveshah> particularly useful for the ULX3S with its relatively slow bitbang FTDI programmer
<trabucayre> daveshah: I used this option all the time since I have an ULX3S :)

<trabucayre> pepijndevos: interesting board ?
<pepijndevos> you mean the seeed one? Meh... just some LEDs and buttons. But hey, good for some blinkys and extending tool support.
<trabucayre> you have pin header
kprasadvnsi[m] has joined #apicula
<trabucayre> but anyway the most important part are the leds :)
<trabucayre> pff It's awfully slow to have a new license :(
<kprasadvnsi[m]> What should I put into GOWINHOME?
<kprasadvnsi[m]> Should it be gowin/IDE/bin?
<kprasadvnsi[m]> I am trying to generate chipDB
<pepijndevos> kprasadvnsi[m], no, just the gowin folder, the IDE/bin is always the same.
<pepijndevos> You can check the Github action and Dockerfile to see how it's done.
<kprasadvnsi[m]> Yah, my gowin path was right but path for xlsx files was wrong.
<kprasadvnsi[m]> Got the correct path from pindef.py and now it generates the chipDB
