07:17 <holonium[m]> Was the sudo pacman -Sy git python that caught my eye from my recollection. Can still do stuff with a partial upgrade and from what I recall, can really mess up a system if the wrong thing is upgraded.

07:18 <holonium[m]> s//`/, s//-pipx`/

10:07 <Ghakotkach> :)

10:13 <Ghakotkach> anyone uses chat gpt?

10:14 <whitequark[cis]> nah

16:57 <r2t2[m]> finally getting around testing my Glasgow 😉

16:58 <whitequark[cis]> nice

17:01 <r2t2[m]> I need to flash a vintage 27C256, I added two SN74HC164 for the address lines

17:02 <r2t2[m]> s/flash/program/

17:02 <r2t2[m]> I thought I use only the serial clock, no direct lower parallel adress lines

17:03 <whitequark[cis]> yeah that'd work, just slow

17:04 <r2t2[m]> I'm first concert to get it to work 😉

17:28 <r2t2[m]> I probably overlook something obvious, this cmd;... (full message at <https://catircservices.org/_irc/v1/media/download/AZWPmuRa9pXqpNT5OyA2A_xQ3Ysp2TCaPxy3QVsQ3jUiRslcj8NQe7Zm6kC8S4N7-XgLW_qIIYOMecjMgnp0aZ1CeSaD2B_wAGNhdGlyY3NlcnZpY2VzLm9yZy9rVWRDZlptU1NZVmpVdktJVUZqenVrYlE>)

17:30 <whitequark[cis]> that's not the exception, that's the source line for the exception. what does the exception message say?

17:33 <r2t2[m]> ah, sorry: amaranth.build.res.ResourceError: Resource port_a#0 has already been requested

17:33 <whitequark[cis]> that should give you a hint; it's probably a default pin assignment (check --help to see what's the default)

17:35 <r2t2[m]> ah, ok - so the data lines default to --pins-dq SET bind the applet I/O lines 'dq' to pins SET (default: 0, 1, 2, 3, 4, 5, 6, 7)

17:36 <r2t2[m]> because serial pins are prefixed --a- assumed the port B would be the data by default

17:38 <whitequark[cis]> it'

17:38 <whitequark[cis]> * it's A for Addres

17:38 <whitequark[cis]> * it's A for Address

17:38 <whitequark[cis]> completely unrelated to A/B on the device case

17:40 <r2t2[m]> ok

17:41 <r2t2[m]> * ok - thanks for clarifying ,-)

17:47 <r2t2[m]> glasgow run memory-prom -V 5 --a-bits 16 --pin-a-clk 9 --pin-a-si 10 --pin-ce 11 --pin-oe 12 read... (full message at <https://catircservices.org/_irc/v1/media/download/Aaepcrdii9Q7qK7BxEgtrvaJOQuKvU5Sntpv6DRGwdwPlgAXpK1hIw6XJLRNG2_CdpDZgrP5FZIpXkLSIIpIKMhCeSaE7tkQAGNhdGlyY3NlcnZpY2VzLm9yZy9UU1VUY3BWcE10ZUlxTEZaVXhjV3ZFUm0>)

17:47 <r2t2[m]> could that be because it expects some parallel address bits?

17:48 <whitequark[cis]> probably

17:48 <whitequark[cis]> I vaguely recall someone fixing that, not sure what happened...

17:49 <r2t2[m]> ok - I can try wiring some bits directly for a test

17:50 <r2t2[m]> adding --pins-a 13 it runs

17:52 <r2t2[m]> unfortunately python is not my strongest suit to just fix the code 😕

18:18 <r2t2[m]> holy shit, maybe it works, 55... (full message at <https://catircservices.org/_irc/v1/media/download/ASY8p0RtXi3xeiDtgQtrX1Rco39x_gqgahhYO3SqRH8m6mIe47R0LaoS8kv9ZCdwyCm24NmMrxnYahSi8aNCUTFCeSaGtAOwAGNhdGlyY3NlcnZpY2VzLm9yZy9kcVJ3blFDTG9PT0RGZXVSaWpzTUROekM>)

18:18 <r2t2[m]> although I thought the ROM is all FF because the vga card came dead to me

18:18 <r2t2[m]> and the RPOM was missing the sticker on the UV window

18:20 <r2t2[m]> * holy shit, maybe it works, 55, aa, 40, e9

18:20 <r2t2[m]> * holy shit, maybe it works, 55, aa, 40, e9, ...

18:21 <r2t2[m]> has someone already designed some add on PCB for PROM interfacing to regularly easier handle flashing? 😉

18:23 <r2t2[m]> https://www.instagram.com/p/DA1TSF8O3XZ/

18:24 <whitequark[cis]> beautiful mess

18:24 <r2t2[m]> yes, how we like it, no?

18:26 <r2t2[m]> thank you for this amazing hw and software ❤️

18:26 <whitequark[cis]> aw, I'm glad you like it

18:27 <r2t2[m]> of course, hopefully more often use it for jtag and uart

18:27 <r2t2[m]> PROM handling was an added bonus, should layout some PCB for that if nobody did yet ;-9

18:27 <r2t2[m]> * course, hopefully I'll more often

21:08 <duskwuff[m]> should probably warn you right now that you'll also need an external power supply - most EEPROMs need >5V on Vcc and Vpp to program (e.g. Microchip recommends 6.5V Vcc and 13V Vpp), Glasgow doesn't go over 5V

21:09 <duskwuff[m]> (and if you're going down the "designing a custom adapter for EEPROM work" road, it'd also be super nice to have a way to put 12V on A9 to put the chip into manufacturer ID mode)

21:41 <icb[m]> Esden did do a PROM board. I don't remember if it's been tested on real hardware yet or not https://github.com/esden/glasgow-addons/tree/master/hardware/prom-addon

21:45 <r2t2[m]> yes, I'm of course aware of ~13V Vpp - and would have plugged in my lab PSU for that. I was hoping I don't need ≥6V though 😉

21:46 <r2t2[m]> oh, that's great! thanks for the hint and link 😉

21:46 <r2t2[m]> s/😉/🙂/
