| 00:13:28 | stgiga | I know it's been a year since I was last here, but I just want to say that UnifontEX now supports Unicode 15.1 (rather than just Unicode 15), and the BDF even has the new characters. |
| 00:29:06 | stgiga | Given the situation with names and all that I mentioned last year (look at the logs), I *especially now* cannot be the one to integrate it, because the site requires real names, something that I don't find to be particularly safe for someone like me, especially given who I'm related to. Then again I joined the net in 2013 despite being born in |
| 00:29:07 | stgiga | 2002, and THAT definitely required an alias. I've always been cautious online. |

| 09:34:42 | speachy | W00fer: Rockbox exists because we don't want to use (or even attempt to tweak) the stock firmwar on mp3 players. |
| 09:37:31 | speachy | nevermind that tweaking the stock OS requires binary patching and jumping through a ton of hoops even after one figures how how/where it does things. |
| 09:39:51 | speachy | I have a hard time seeing how that 'about rockbox' thing is due to a41a001, as that should only affect multivolume/multidrive systems, and the nano2g isn't. |
| 09:40:32 | speachy | but maybe it's hitting a different codepath that is broken. |
| 09:41:59 | speachy | stgiga: thanks for the heads-up, I'll look into it. I'm not sure we're technically able to utilize the extra glyphs due to our fonts bing limited to 16-bit character numbers. |

| 10:08:02 | speachy | stgiga: oh, you said you had a question? |
| 10:32:08 | W00fer | @speachy: I know. But since Rockbox is very power hungry going back to the stock OS is for now needed.... |
| 10:32:36 | W00fer | And it would not hurt to know why the stock OS does not work and Rockbox does on the accessory protocol. |
| 10:33:27 | _bilgus | so like I feel like the better choice is to work on ipod power consumption in RB from our side if we were to put any effort towards it |
| 10:33:50 | W00fer | The only option I heard is shutting off the harddrive |
| 10:33:55 | W00fer | But |
| 10:34:01 | _bilgus | W00fer, if you figure that out lets us know.. |
| 10:34:36 | W00fer | Ipodlinux has it already in reverse since 2007. By disabling cache the hdd always runs. So maybe it's not shutting off the harddrive but making the cache work |
| 10:34:54 | _bilgus | the disassemblers haven't gotten much better Reverse Engineering binary code is no fun |
| 10:35:09 | W00fer | Even Ghidra or IDA Pro? |
| 10:35:26 | _bilgus | names that are big its still not trivial |
| 10:35:54 | W00fer | It's native ARM code but who is working on the iPods? |
| 10:36:11 | _bilgus | better effort to hook an ipod to a current shunt and start experimenting |
| 10:39:15 | _bilgus | well you pull up some ghidra and try to figure out where the real entry point is after a few days you'll find it and you might get a few libc functions that it figured out the rest is wall of 100000: LDR1023 MOV123 ASL |
| 10:40:22 | _bilgus | without an area to go secifically or some real source to match it to you might as well go looking for the holy grail |
| 10:52:17 | _bilgus | SO I noticed something weird plugins don't scroll properly in the sim |
| 10:54:24 | _bilgus | it works fine in core as theres a reoccurring full screen update called but not so for the plugins and works properly on device |
| 10:54:46 | _bilgus | its almost like update_rect is ignored |
| 10:56:46 | _bilgus | I can add my own lcd_update() and it works but if I convert the current rect_update to full screen (they both use the same underlying function) it doesn't work, so maybe a race?? |

| 14:15:27 | W00fer | _bilgus: what is a current shunt? |
| 14:16:17 | _bilgus | its a precision resistor that allows you to measure a voltage across it tat corresponds to the amp draw |
| 14:18:31 | _bilgus | for instance while the screen is on you might get .05 volts and that might be 5 ma across the current shunt then when the screen is off it might read .01v and you now know the screen draws 4ma |
| 14:20:13 | _bilgus | https://en.wikipedia.org/wiki/Current_sensing |
| 14:31:42 | speachy | another approach is to poke at the PCB to figur eout where the hard drive power comes from, |
| 14:32:36 | speachy | and from there figure out if there are any control lines (eg a power MOSFET connected to a GPIO) |
| 14:33:04 | speachy | and trace those control lines to where they originate (eg a specific pad on the main SoC) |
| 14:39:59 | _bilgus | ^with that info you now at least have a needle to go looking for in a disassembly it might also allow you to figure it out directly in our drivers which would likely be a far less daunting task |
