Zaurus - Other distros support / Re: YT video about Zaurus and intel arm

Yeah, and directly filming the LCD was too difficult with a cam because the LCD reflects too much light and it acts as a mirror.

I believe your bootloader is shown at

v3-rev, is shown at 13:16
Aha, missed it, it shows a bit more of this. Is that clip showing it running on an emulator?

Varti

It shows a serial connection to a C1000 running my bootloader as common application on GNU/Linux (Gentoo 2009, kernel 2.6.24).

The serial connection (115200bps 8data 1start 1stop no flow) was recorded on a GNU/Linux laptop running GNU/screen.

Screen works better than minicom in this case because it offers full terminal support!


Linux filming Linux :)

I have a YT channel, too.
Not yet uploaded a video, only helped a Youtuber, filmed and passed him a video clip.
I think I will upload a video with the new versions of my bootloader.

It keeps getting better and better  :D

I helped a YouTuber make a video about Zaurus, we got about 30,000 views
(yes, the bootloader shown in the video ... is what I am still developing ... not yet completed, but it starts working)

Do you mean external hard drive?
If so, you d best use externally powered units

Code: [Select]
mykboot-v5-r30_modified $ make run
mykboot_init ...
fb_init_mode_set()
Switching to 32bpp mode ...failure
Switching to 24bpp mode ...failure
Switching to 18bpp mode ...failure
Switching to 15pp mode ...failure
Switching to 16bpp mode ...success
angle = 90 detected
fb_init_geometry_set(): 480 640 16

That's compatible with what I observe from ioctrl  :o :o :o

Zaurus - Hardware discussion / C1000, C3xxx: is the PXAfb/LCD 16bpp?
« on: July 02, 2025, 05:41:39 pm »
Only consider 640x480: is the PXAfb/LCD 16bit per pixel? RGB565?
doesn't it support 8 bit per color? RGB888?
doesn't it support 6 bit per color? RGB666?

I wrote a framebuffer application, from my testing, it seems 16bpp only.

Is it correct?

I guess the simplest way to fix this is to by editing the update.sh script to remove the need for the microdrive. The file itself is encoded with a simple character substitution algorithm, here's a simple program to encode/decode it: endecsh.c at the bottom of this page:

I wonder what the point is in coding a script that absurdly...
In any case, this is where it probes for the microdrive.

Yes, the Zaurus section of the forum unfortunately has a very low activity since many years, which is expected since only the SL-5500 and SL-6000 models were sold outside Japan. I still have my collection of Zauruses and switch them on from time to time, I read the posts here with interest.
I suspect there are other users following the various threads but they never answer. We have a views counter for each thread, there are between 5000 and 19000 views for each of them, though most of them are be probably made by bots. I prefer to keep the subforums open for read-only access for non-registered users, so that it's easier for Google to index the pages and make the information here more accessible.
Other users that have posted here in the past are probably following this subforum. To any of you, please post here so that we can have a rough idea of how many of us are here.

But C1000? C3xxx?

I wonder what's the point of reading without ever replying  :o :o :o
I've opened several topics, with zero interest, I'm developing a bootloader, and I've written about this thing, again with zero interest.
I've asked for patches, and I've had no answers, I've asked about the microdrive, explaining the matter well, and I've had no answers.

I mean, frankly, it's so bloody frustrating this way ...

From what I see the interest in Zaurus is very low, weeks without posts, is there anyone still here?

hi
I am developing my own bootloader, supporting
- C1000
- C3000

yesterday I prepared an SD card
- PC partition FAT16
- mkfs.fat

then I copied
- update.sh
- zImage <----- my application

I followed the instruction to enter the Sharp Menu.
As result:
- C1000 perfectly flashed, now it boots my bootloader
- C3000 says it can't update anything "because the microdrive is missing". No option.

I removed the microdrive because it was faulty, the C3K is designed to boot completely from the SD card. I still need to find and buy a replacement for the internal MD.

It's absurd that update.sh refuses to flash because the microdrive is missing ...

Any workarounds?

14
I know there is a JTAG interface inside the PXA270 SoC.
I don't know if it is connected to a PDA connector.

Any doc?

15
In particular, I'm trying to figure out what problems there are with
  • Flash on Zaurus -> can I erase everything and use the Zaurus Flash (C1K, C3K) for my stuff?
  • Suspend/Resume
  • PowerCharge
  • PowerManagement
  • TouchScreen -> too noisy on a SDL application I wrote to take notes -> should I put a software filter into its kernel module?!?
  • USB, why is it so slow?!? I get ~1Mbyte/sec on a 10/100Mbps USB-NIC ---> it's not USB2, but rather USB1?!?

I also found a Russian forum that was about Gentoo/Zaurus around 2009.
I see patches for kernels 2.6.22 and later.
