Zaurus - Void Linux support / Re: Void Linux Packages
« on: April 06, 2025, 02:50:56 pm »
Hi,

I am running Kernel 4.19.0 from build-008 and I have a question regarding power management. It seems that (compared to NetBSD but also older kernels from e.g. Cacko) the power management code has issues when I use it with USB Wi-Fi dongle. It very often reads low/critical battery voltage (probably due to a short term peak power draw from the dongle) and forces standby - while not turning on offline charging mode. So once in standby, device can't be charged because charger hasn't been put to offline mode.

The problem also appears in the kexecboot 3.x kernel. This usually manifests itself so that when device reaches kexecboots, the power management code reads low battery and forces it into standby - while again not enabling offline charging. Once in this mode, devices can be woken up for a second, only to go back into standby again.

Has anyone noticed this too? Did the power management code for zaurus get any updates in the 5.x kernels?

I've found e.g. Dell Axim x51v which has VGA transflective screen that is also 3.7 inches (http://www.kodeks.hr/Assets/Pdf/axim_x51v.pdf). The hardware spec is very similar to Zaurus, which makes me think/hope screen swap would be easy as they probably use same pinout/cable.

Yesterday I was coding on the go on my C3200 and I must admit that the screen is almost unreadable in moderate daylight. 

I remembered that some of the xScale based PDAs from the era had a similarly sized screens that were transflective, so I thought that maybe they would work with the LCD controller in Zaurus without any modifications? Did anyone maybe succeed in transplating one into the Zaurus?

Zaurus - Hardware discussion / Re: microdrive compatibility

Hi DiTBho,

does it have to me microdrive? After mine died I replaced it with a CF card. There is even CF to SD adapter that worked fine too in my SL-C3200

Zaurus - Void Linux support / Audio doesn't work (crashes)
« on: January 07, 2025, 05:43:16 am »
Hi, I'm using voidz with 4.19.0_1 kernel - the issue I am having is that as soon as I play something (aplay or mpg123) the system crashes. It is the same error message as described in https://lore.kernel.org/linux-arm-kernel/d803b938-3212-6485-8786-43dff6e46e6a@zonque.org/T/

Did anyone else manage to get audio working on voidz with above kernel, or are there alternative (newer? older?) kernels that work?

Are there any tips on how to build void-packages for zaurus myself? What is the state of cross compilation, can all packages included in e.g. build8 be cross compiled on x86 host machine?

Zaurus - Hardware discussion / How does CE-RH2 work?
« on: November 11, 2024, 08:14:22 am »
How does Zaurus remote actually work? I tried reading driver sources, but these seem to read PXA GPIO chips, which I guess means that some chip already processes remote input and passes it to SoC? Is it using some well known standard for this? Are there any known replacements that work as CE-RH2 is very hard to find in 2024.

Correction: it seems that standby is working, but it's not activated on lid close... When I press On/Off it seems to suspend and resume fine.

Zaurus - Other distros support / NetBSD 10.0 on Zaurus C3200
« on: November 04, 2024, 08:55:21 am »
Hi everyone!

I just got Zaurus C3200 in 2024 :) and wanted to report that current NetBSD (10.0) installs and works fine! Audio works, backlight, D-Link 660W all seem to work fine, basically everything works except standby. The LCD goes dark on lid close though. I had a problem booting NetBSD from Cacko, but rescue kernel works fine for bootstrapping. There is lot of precompiled packages for armv4 (see https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/earmv4/10.0_2024Q3/All/) that can be installed with pkg_add, and what's not there I am building from using pkgsrc on the device. It seems that default zaurus kernel doesn't include some modules like urtwn driver for the USB Wi-Fi dongle I have, so I am looking into recompiling a tweaked kernel with the module included.

Btw. OpenBSD 6.0 also installs and runs almost fine but I had a lot of issues with screen going white when there was a lot of CF activity while on battery. I guess it's some kind of power issue, maybe it's overzealous in interpreting low voltage from the battery and going to standby or something. Since 6.0 is last version that supported Zaurus and it's very old, I didn't want to invest lot of time into debugging it and went to NetBSD instead.

Hello!

I just managed to boot build8 voidz using instructions here (thank you for all the work!) and the Zaurus won't do standby when I close the screen. Do you have any hints on how to add standby support, is the kernel 4.19.0_1 supporting it? Is it only about missing apm?
