digshadowmithro: looking at your pr17:59
mithrodigshadow: Yeah - I can merge if it looks good18:00
mithroelms: What was the dep in my repo but not upstream of your iceram patches again?18:02
digshadowMessage: Failed to find block type 'DSP' for grid location specification18:02
digshadowthat sounds like a different issue though18:02
digshadowI think the original issue is fixed18:03
mithrodigshadow: I can fix that one too - just got a meeting now18:04
digshadow+# FIXME: Move this into icebox18:05
digshadowwhat is it that you want to move in?18:05
elmsmithro: you added blink testbench and had changes for checker simulation. The only commits that I think matter are the "Fix RAM pin metadata for rr_nodes" and icestorm version, but hopefully that PR on icestorm will merge.18:15

digshadowif this sounds reasonable to you, I'll file an icestorm ticket23:10
mithroHrm?23:12
mithroOh23:12
mithroWhat is the second one?23:13
mithrodigshadow: Yes, please add that to icestorm23:13

digshadowwhat about it? 5k is supported there23:15
digshadowor a warning not to test say 3k23:15
mithrodigshadow: maybe should be adding the lm4k as well?23:36
elmsdigshadow: I just ran into icebox_hlc2asc and can put up a PR as soon as I test it23:37
digshadowelms: cool. Should I not file any issue then?23:37
elmsdigshadow: Still need to test it out: https://github.com/elmsfu/icestorm/commit/b9be24580d0d5d8620b5966ce3ad268cf6c57c2123:46
tpbTitle: icebox_hlc2asc: add support for 5k and lm4k devices · elmsfu/[email protected] · GitHub (at github.com)23:46
digshadowelms: if you think that "probably works" I'll suck it in and try it out23:47
awygle"probably works" is a good description of the state of lm4k support, jsyk23:48
digshadowhehe23:48
digshadowawygle: fwiw I'm interested in 5k more23:48
awygleyeah for what y'all are doing 5k is a better platform in several ways23:49
awyglebut might as well toss lm4k into your switch statements23:49
elmsdigshadow: I got a bin file for the 5k, but will have to come back to flashing it on hardware later.23:50
digshadowelms: thats probably good enough for me right now. I just doing as reported performance testings of various tools23:50
