00:06 <spongebobsr[m]> I'm trying to install the glasgow digital inerface explorer for the first time. Having followed the instructions on glasgow-embedded.org, I still don't see the device showing up in dmesg. Anyone know of any issues?

00:12 <duskwuff[m]> If the device is getting power but isn't showing up in dmesg, there's probably something wrong with your USB cable. Try another one

00:12 <duskwuff[m]> You don't need any software installed to get the device to enumerate.

00:17 <spongebobsr[m]> goofy. I managed to see it enumerate once while reorienting the cable it came with. haven't gotten it to do it since. I may have to break out some tools

00:18 <spongebobsr[m]> possibly an issue with my hub too

00:19 <spongebobsr[m]> and it was the hub. thanks

00:30 <cdwilson[m]> FWIW, I was unable to enumerate when the Glasgow was plugged into my USB hub. However, when I plugged it directly into my mac it enumerated correctly

07:23 <axiesmoothie[m]> so I found the old board I was working on 3 years ago, it had a combined 4gb slc nand flash and 2gb lpddr2 chip, trying to determine how it can be talked to, attaching datasheet

07:43 <Actually64Dragon> Hmm... "how it can be talked to" is a broad thing... I can parse what the datasheet says. I have no idea, yet, where to begin translating that into python for this thing. I believe there were some example code sets/tools included in the base build that do flash access. I'm not sure if they take arguments to customize them, though. This thing looks a little weird in that it uses 5 cycles for addressing with the last

07:43 <Actually64Dragon> cycle just using one pin.

07:55 <axiesmoothie[m]> it seems to describe the protocol inside the datasheet but im unsure if thats just ONFI which Glasglow already has an applet for or compatible or completely custom, anyways it has to be standard in some way because its part ot a quectel ec25 based custom board and is used by a qualcomm mdm9207 modem chip which probably just implements a standard nand controller which probably just speaks ONFI??

07:57 <axiesmoothie[m]> NANYA (company behind the nand/ddr2 chip) advertises making JEDEC compliant chips

07:59 <Actually64Dragon> I know there is a JEDEC program in the various files included in the build. I am not sure if this is a JEDEC protocol, however. I'll see what I can pull up and figure out if the protocol in the datasheet is JEDEC.

08:15 <axiesmoothie[m]> The pin description seems very similar to what glasgow expects so probably that's ONFI or close

08:20 <Actually64Dragon> I'm not sure if this will work, as I needed to create a login: https://www.jedec.org/system/files/docs/JESD68-01.pdf I am not that familiar with the nomenclature used for Flash protocols, but the JESD68.01 defining the Common Flash Interface seems to have a similar pin arrangement, but I am not entirely sure what they mean by "98H". The device in question specifies "80H" ...and where I'm from H is Henries, which is

08:20 <Actually64Dragon> clearly not what is meant, here.

08:38 <Actually64Dragon> https://onfi.org/specs.html Digging through some of these at the moment. I'm basically just trying to find a protocol description that resembles the clock/bus timing charts in the device datasheet to compare and contrast with. Page 150 of the ONFI 4.0 standard is roughly what I am talking about.

08:43 <Actually64Dragon> Page 169 of ONFI 4.0, Table 90 specifies command values that correspond to the table on page 19 of your device datasheet. Or, seems to mostly conform.

14:49 <axiesmoothie[m]> I wish there was readily available and cheap breakout boards for all kinds of BGA/FBGA chip packages so that you could desolder chips like FBGA 162 nands and just solder them to those breakouts to dump them

14:51 <whitequark[m]> same... I was going to design some for 1b2 as a companion for Glasgow

14:51 <whitequark[m]> but then I got more sick and a war escalated and those plans got kinda shelved

14:52 <axiesmoothie[m]> Damn I'm down to reboot that project

14:52 <axiesmoothie[m]> I just tried to solder magnet wire to it and yet again gave up

14:55 <axiesmoothie[m]> With all that happened for various reasons we definitely stopped living for a few years there

14:57 <axiesmoothie[m]> The closest I found to what I want is: https://www.chipquik.com/store/index.php?cPath=900_1200

14:57 <axiesmoothie[m]> But it doesnt have FBGA 162 to DIP, apparently FBGA stands for Fine Pitch BGA

14:57 <whitequark[m]> oh that's a cool store

14:57 <axiesmoothie[m]> Many chipquik products are sold by Mouser too, though don't know if those boards are

14:59 <axiesmoothie[m]> Since ZIF sockets are so expensive, and understandably so, I believe simple soldering breakouts would do the job

14:59 <axiesmoothie[m]> I guess just have to be careful with the repeated high temperature exposure to the chips, as I probably already made it suffer too high temps, anyways its just a test if its corrupted it's not huge deal

15:00 <axiesmoothie[m]> I was thinking maybe it was possible to make something with resin printers and pogo pins for diy bga "zif" sockets but dunno how precise the resin printers can get

15:01 <axiesmoothie[m]> + I don't have a resin printer, I just know a regular 3d printer just wont be good enough

15:01 <benny2366[m]> one moment please

15:01 <benny2366[m]> i might have some links that you will find intresting

15:02 <axiesmoothie[m]> Thanks

15:02 <benny2366[m]> https://jlc3dp.com/3d-printing-quote

15:02 <benny2366[m]> https://www.pcbway.com/rapid-prototyping/manufacture/?type=2

15:05 <axiesmoothie[m]> Good to know they also do resin, though I'm not sure I would be able to design something and be certain that it works after I receive it

15:06 <benny2366[m]> that's also a risk if you diy it imo

15:06 <miek__[m]> time to employ the bouncy grid array https://www.topline.tv/images/CCGA1152T1.0M-DC346D_Detail_1000x700.jpg

15:07 <benny2366[m]> ai right ?

15:09 <whitequark[m]> ah, a classic

15:10 <SnoopJ> finally, stable floating point

15:29 <axiesmoothie[m]> Found a gold mine of a store.. https://www.proto-advantage.com/store/ I think it's another chip quik brand, I'm checking if they got the breakouts I'm looking for

15:31 <axiesmoothie[m]> They don't.. 😐 seems to be the same catalog as chipquik

16:29 <axiesmoothie[m]> Found the perfect board on some sketchy phone repair sales site, would need to make something like that, if it's all in one even that's even more cost-effective

19:03 <axiesmoothie[m]> I just realized that what chip quik is selling is already usable, they are grid patterns with various pitches, they are quite generic

19:03 <axiesmoothie[m]> https://www.proto-advantage.com/store/product_info.php?products_id=4000033 is 0.5mm pitch like the chip I have, the entire chip wont fit but the NAND part that is relatively small will, therefore I think I might be able to use the board to do a partial BGA solder (if that works..), the chip will stick out on either end of the footprint without being soldered on there I guess, but at least I'll have access to the important NAND pins

19:03 <axiesmoothie[m]> reliably
