Zaurus - Arch Linux ARM support / Re: Update: C1000 / Akita support

« on: April 27, 2025, 01:21:30 pm »

hi
I applied all the patches found in Void, to vanilla kernel { 5.0-rc3, 5.4.229 }.

Code: [Select]

~ arch/arm/mach-pxa/spitz.c
~ drivers/mmc/core/slot-gpio.c
~ drivers/mmc/host/pxamci.c
~ drivers/mmc/host/mmc_spi.c
~ drivers/mmc/host/of_mmc_spi.c
~ drivers/ata/pata_pcmcia.c
~ drivers/pcmcia/soc_common.c
~ drivers/pcmcia/soc_common.h
~ include/linux/mmc/slot-gpio.h
~ include/linux/platform_data/mmc-pxamci.h
~ include/linux/spi/mmc_spi.h
(patches, modified these files)

Tested on my c1k, both k5 kernels boot find, but the suspend does not work at all.
When I press the suspend button, the screen makes a bright flash.
Sometimes the screen even goes white, and I can't see the text console anymore.

Is there any datasheet of the Zaurus LCD?
Pintout? detailed datasheet?
Otherwise is just speculation.

Zaurus - Void Linux support / kernel patches? to Vanilla

« on: February 25, 2025, 08:22:07 am »

hi
I am in the process of resurrecting my old Gentoo Catalyst arm-v5.
Zaurus is one of the two targets.
I'd like to write some overlays for emerging the kernel, in this case I'd like to use a Vanilla kernel + patches.

Is there a repo with the patches, or do I have to extract them by comparing a "modified/hacked" kernel with a "vanilla" kernel?

hi
I remember there were datasheets and partial schematics about the components used in Zaurus C1000 and C3000.

Unfortunately I am not able to find them.

I am going to repair a dead C3000 motherboard
+ flash to be desolder and replaced
+ dead microdrive
in the process I will also desolder the IRda port, and reuse the serial contacts for something else.

Let me know

« on: February 17, 2025, 08:38:16 am »

hi
I am looking for a Hitachi HMS360404D5CF00 known to be working with Zaurus PDA or in a 3.3V CF machine (e.g. Mikrotik rb532a router).
Let me know if you have one, or if you know what I have exactly to search.

Thanks

Same Hitachi model, and this time it responds to the ATA identify command and to every ATA sector_read command

Zaurus - Hardware discussion / microdrive compatibility

« on: February 17, 2025, 08:20:35 am »

hi,
after 10 years of service, my Hitachi microdrive died.

• Hitachi HMS360404D5CF00, 4GB

No problem, I have the full backup of the rootfs, the problem is just replacing the broken disk with a new one.

I bought exactly the same model on eBay, but... surprise surprise it is not recognized by my C1000.
Then I returned the drive to the seller and tried a new one. Same behavior, HMS360404D5CF00 not recognized.
Then I tried a Seagate ST1, ST650211CF, which exhibits even stranger behavior:
it responds correctly to the ATA identify command, but panics on every ATA sector read command

(this is a firmware I wrote for a MIPS32/le router, it has a 3.3V CF, exposing the same behavior I see on my C1000)

Some "OEM Only" drives use the CompactFlash form factor but only provide a 5V IDE/ATA interface.
These will not work in readers or devices which expect a 3.3V interface and full CompactFlash functionality

looking at the Seagate ST1 datasheet, I verified it's LBA28 capable.
I don't see any weird pre-init ATA commands.

(The Seagate 5GB on the CF_usb adapter passed all the badblocks tests!)

So I put both the two new MicroDrive into a USB_CF adapter, to check them with GNU/Linux, and ... surprise both perfectly worked with the USB_CF adapter, which operates at 5V. Badblocks passed, zero error reported!

My guess...the Zaurus C1000 CF module must be 3.3V, while these two microdrives only operate at 5V!

The Seagate datasheet vaguely says 3.3V/5V, however ... on the back of the Seagate microdrive it clearly says "+5V", and in fact it does not work on machines with CF powered at 3.3V.

There is no extra label on the Hitachi HMS360404D5CF00

Comparing the microdrive that worked for 10 years on the C1000 with the new one that is not even recognized (does not respond to the Identify command), no difference is noticeable, same production number, same label...

My guess is there are actually two versions

• Hitachi HMS360404D5CF00, 4GB, 3.3V/5V
• Hitachi HMS360404D5CF00, 4GB, 5V-only

According to Google, not only there are also OEM versions ... but also custom IBM-made versions for their MIPS WinCE-v1.0 laptop (only sold in Japan), marked "IBM Microdrive" but made with Hitachi parts, who also made the Apple iPod drive, and whatever Apple, IBM or Hitachi microdrive you look at ...
... they are not easy to identify as "OEM" or "non-OEM", as there is no indication on the label!

Some Hitachi microdrives made for Apple iPod have a log on the front, usually the Apple logo, which means it is an OEM drive, 5V only, True-IDE only,
but other Hitachi microdrives have no indication at all.

- - -

is there a list or something about the microdrive compatibility with Zaurus PDA?
