14:59 <whitequark> i wonder what the hell goes wrong there

14:59 <whitequark> why does abc crash

14:59 <d1b2> <gatecat> it's not abc crashing afaik but the yosys abc integration

15:00 <whitequark> oh

15:01 <whitequark> ohhh yeah

15:01 <d1b2> <gatecat> something going wrong with temporary directory creation ig

15:01 <whitequark> oh, yowasp stopped mounting those

15:01 <d1b2> <gatecat> the abc9 path should be preparing a temporary directory to put the various stuff abc needs into and I guess this is the first time it tries to open a file there

15:01 <d1b2> <gatecat> ahh

15:02 <whitequark> and VioletEternity uses on Windows

15:02 <whitequark> ... because it was broken on Windows

15:05 <whitequark> oh well

15:05 <whitequark> :s

15:07 <whitequark> so this doesn't actually fail on Linux?

15:07 <whitequark> oh.

15:07 <whitequark> oh that's because it has /tmp

23:34 <FFY00> hey, I am trying to dump the firmware of a HD6473388CP10, which AFAICT needs to be put in PROM mode, by setting D0 and D1 to high, and then it can be read like a normal PROM (they say it's compatible with a HN27C256H)

23:35 <FFY00> I made the following changes, to implement this (just playing with it for now, not code to submit), but I'd just like for someone to double check it's correct, as I don't have much experience writing applets https://paste.xinu.at/Zw8I6P/

23:37 <FFY00> right now I'm running on 5.5V, instead of 6V, and I only zeros, so I wanted to confirm my patch is correct, and that the issue comes from somewhere else, the voltage probably

23:37 <whitequark> oh, interesting

23:37 <whitequark> do you have a datasheet link?

23:39 <FFY00> yeah, 1s

23:39 <FFY00> https://pdf1.alldatasheet.com/datasheet-pdf/view/83027/HITACHI/HD6433308.html

23:39 <FFY00> section 13

23:40 <FFY00> actually, it says "Set read mode Vcc = 5.0V ±0.5V, Vpp = Vcc" here

23:40 <FFY00> so 5V should be fine

23:40 <FFY00> and the issue might be me not setting Vpp

23:41 <FFY00> never dealt with PROM interfaces before

23:41 <whitequark> how are you connecting the PROM?

23:42 <FFY00> I made an adapter to adapt the microcontroller to a HN27C256H footprint and am just running jumpers off that

23:43 <whitequark> it has way more pins in EEPROM mode than Glasgow has, how are you dealing with it?

23:45 <FFY00> not connecting all address pins right now

23:47 <whitequark> I think you might not be waiting before a read cycle

23:51 <whitequark> (I'm going to sleep, talk to you tomorrow)

23:52 <FFY00> gotcha, good night

23:54 <whitequark> night!
