Zaurus - Hardware discussion / Re: NAND-Bricked my SL-C750 and looking for bootloader copy

« on: June 16, 2021, 07:25:12 am »

Thanks, I'm considering to obtain a new one. Played with my semi-broken and found an interesting moment. I played around diagnostic menu and make this – first attempted to NAND Erase (anyway it's nothing to lose for me), got an error (ecc related, as I can remember), then activated option NAND Read&Write Rpt. Strangely, but this thing worked – procedure was ended without error, and after this option NAND Bad Blocks says it's none founded and everything is OK. But device still not working properly – after choosing "EXTRA" – "Zaurus Test" – "Reset" (or "Off") no reaction to pressing on "Power" button and both LED constantly on (not blinking). After removal of battery it even stops doing this, and only reboot from diagnostic menu returns LEDs to work. Also tried to run NAND CheckSum, and got NG status on positions ROFLSYS and PRESET. Tried to flash NAND Backup, downloaded from Trisoft.de – it's restoring without error (only from 1 Gb SD, CF still not working), but no help at all, device is still dead. It's definitely a hardware issue?

Zaurus - Hardware discussion / NAND-Bricked my SL-C750 and looking for bootloader copy

« on: June 15, 2021, 04:17:13 pm »

Hello, it's me again! It seems I've played with Zaurus too much: after brute force reset (just taking off battery) device is stopped to power on, LEDs not working, combo keys like OK+Power, D+M, D+B not working too. But C+D combo still works: on an empty CF card Mail LED started flashing. On old Russian  forum HPC.ru I found that this means I need to recover my bootloader. Unfortunately, I was unable to find anything about it. The NAND Backup (like those DBK files, obtained from Trisoft.de) is useless in my case?

Tried Fn+D+M combo, worked but after moving DBK on formatted CF and inserting it I got message "Can not initialize CF". What is that?

Used 1 Gb SDcard, NAND restored, but device is still dead. This means that built-in flash memory died?

Unfortunately yes, 4096 bad blocks in NAND. Too bad(

Hello again and thanks for reply!

For the qpose issue, there's a how-to here which might be helpful: http://zaurus.kruss.com/howto-qpose.php

Unfortunately, how-to has no help 'cause in my case the emulator's GUI itself not starting -- according to screenshots I found there, it could be opened without PalmOS ROM. I'm uninstalled libSDL and tried to start qpose without it but to no avail. Maybe, I should try to start it via terminal but I doesn't know, how to do this: when I'm entered command qpose, system says that my display is 480x640 and this is all.

For the Java error: in your Java installation, the installed System class doesn't have a setProperty() method, or it doesn't expect two Strings as parameters. See if you have more than one "System.class" file, if so, check which of them is being used at run time by adding

Code: [Select]

-verbose:classin your command line.

Added this argument and got something like this:

Zaurus - Other distros support / SL-C750 and some software issues

« on: June 13, 2021, 05:57:26 am »

Hello again! After my hardware shenanigans I'm stuck with some software troubles. Main thing – PalmOS emulator qpose. I'm installed it (both bin and data packages), obtained a ROM from site PalmDB, but upon starting emulator says "Please wait..." and after a couple of seconds closes without any error. Also it's starting with incorrect screen position (portrait instead of landscape), and libSDL installed (working, tested with emulator zgnuboy).

Second issue – Java, J2ME MIDP. Why – wanna run Opera Mini, just as proof that my little outdated device can browse modern internet. I found a pretty detailed instruction (here, section "MIDP"), made as it says, upon executing run command – in my case it looks like this:

Spoiler: ShowHide

Code: [Select]

evm -classpath ./me4se.jar:./midpx.jar:./opera-mini-8.0.jar org.me4se.MIDletRunner Browser

I've got an exception which looks like this:

Spoiler: ShowHide

Code: [Select]

Exception in thread "main", java.lang.NoSuchMethodError: java/lang/System.setProperty(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
        at javax.microedition.midlet.ApplicationManager.setSystemProperty (bytecode 21)
        at javax.microedition.midlet.ApplicationManager.<init> (bytecode 186)
        at org.me4se.MIDletRunner.main (bytecode 147)

My code-experienced friend said that this is some locale issue, so someone can help me with that?

Zaurus - Other distros support / Re: SL-C750 and PRISM3 chipset WLAN CF Card

« on: June 11, 2021, 05:48:24 am »

Thanks again, but actually I was able to make that thing work. It seems that this card is working with Cacko ROM – I'm just added it's entry to file hostap_fw.conf in /etc/pcmcia. Entry is gotten by console command

Code: [Select]

cardctl ident IDK if it matters, but I named my card as "Gemtek WL-672". Also I'm added a SanDisk Connect+ firmware to etc/firmware directory, file sf010704.hex, and installed sandisk-plus_arm.ipk. After this and a couple of reboots Zaurus recognized card fully and is able to made a connection. Unfortunately, Cacko ROM kernel not supporting WPA, so only the unsecured connections are recognized (made a access point from my Android phone).

Zaurus - Other distros support / SL-C750 and PRISM3 chipset WLAN CF Card

« on: June 10, 2021, 02:50:57 pm »

Greetings! I bought myself a SL-C750 Zaurus recently, for playing around a Linux-based PDA, and immediately flashed it with Cacko ROM 1.2.3 Full (most popular and stable ROM for that model AFAIK). Almost immediately I found a CF WLAN card on Ebay and purchased it – model is Verifone WL-672 (rebranded Gemtek WL-672) but found that inside it has a Prism3 chipset instead of Prism2, fully supported by Zaurus ROMs. Of course, it's not working: PDA is recognizing it but as generic Intersil Prism2 card, not Prism3, and shows a yellow triangle in "System Info" app. AFAIK Prism3 chipset at the times of Zaurus' glory was found only with SanDisk Connect+ and old page from this site (via Archive.org) says that Prism3 should working as Prism2.x, but not in my case, I'm afraid. It is possible to make that thing work? Thanks in advance!
