Gemini PDA - Linux / Re: TUTORIAL - complete DEBIAN INSTALL with 4G working

« on: June 04, 2021, 08:55:59 am »

Replying to my own question just above, it must just be the version of hwclock that does not work. I wrote a very simple program to call ioctl with RTC_RD_TIME and RTC_SET_TIME and both worked fine so the RTC can be set from the system clock  before shutdown and then is maintained.

Gemini PDA - Linux / Re: TUTORIAL - complete DEBIAN INSTALL with 4G working

« on: May 20, 2021, 09:11:52 am »

I am new to the Gemini PDA and only bought it because it can run Linux. I don't really know Android at all so I thought this tutorial would be great for me. I have not followed all the steps yet so bear that in mind. I am stuck on one thing - the real time / hardware clock. With only Debian, whenever I shutdown I lose the system time - jumps back to 2016. However if I dual-boot and set the date/time in Android then shutdown and then boot into Linux the date/time is current. So, clearly I think, the date and time can be maintained through shutdown but Linux is not setting the RTC. I tried hwclock but it says "Inappropriate ioctl for device" so I assume Mediatek do not use rtc0. Can anyone point me in the right direction, please?

C1000/3x00 General discussions / Compact Flash Card Applet

« on: December 29, 2010, 08:31:13 am »

There is now a version 2 of this applet which supports the Sharp Network services. Consequently it now does support Ethernet-type cards and services. Also you do not need to set up a dialup PPP service manually (I just prefer to). It has been tested on the SL-C3100 (Borzoi), mainly running the Sharp ROM, and to a lesser extent using Cacko. The cards used for testing (apart from normal data/memory CF cards) were an Audiovox RTM-8000(P) GSM/GPRS modem, a TRENDnet TE-CF100 Fast Ethernet Adaptor, a Netgear MA701 802.11b Wireless, and a "Blue Monkey" Bluetooth.

The original link to read more about is still valid.

Sharp ROMs / Extract Or Mount A Nand Image?

« on: December 06, 2010, 11:06:49 am »

Just in case it helps anyone else.

I had a NAND backup of my SL-C3100 which would not restore (and I tried just about everything before discovering this topic).

I restored an old NAND backup, and then used the nand_ripper script to get the root and user partitions from the one which would not restore.

However, instead of mounting them and recovering the data, I copied them to an SD card, booted into console mode ( D and B ), and copied them direct to the mtdblock partitions:

Code: [Select]

dd if=/mnt/card/nand_root of=/dev/mtdblock2
dd if=/mnt/card/nand_user of=/dev/mtdblock3
It worked a treat, and I was very relieved!

Richard

Thanks very much for the update - I was hoping for some feedback.

On the SL-C3100, the install does not cause a reboot - just a reload of the applets?
If you could install manually and capture the stdout and stderr and send it me that would be good.
Or did you mean the messages are during reboot?

At least you got the "L" in taskbar - that's something. ;-)

Did you mean becomes D (not M) with the memory card? Data/memory cards should give D and prompt for a mount.

I had completely overlooked Ethernet cards. :-(
I am looking to add them, but unfortunately I do not have one to test it.

As for the Audiovox card, the /etc/ppp network does not matter at this point, and it is supposed to wait for a signal but time out after ~20 seconds and 'eject' the card if there isn't one (icon back to 'L'). I tried mine without a SIM card at all, and that's what happpened.

I don't believe install/uninstall should affect anything but netmon and cardmon (and those should be back as they were).

Would you be interested in having a version with debug logging and sending me the output - I might be able to sort something.
Fully understand if you do not want to spend time on this.

Hi

Not sure whether anyone will be interested but I have written a CF card applet which is designed to replace the original Sharp cardmon and netmon applets.

It mounts data cards (obviously) but also controls serial (modem) cards.

It has 2 additional optional modules which allow SMS (texts) and Voice.

I am using it on a SL-C3100 running the Sharp ROM with an Audiovox RTM-8000 card, which is the only setup I have tested it on.

You can read more about it, starting at http://humbug.me.uk/zaurus/hbzcard.README.FIRST.htm

Software / Kernel Patch

« on: August 02, 2010, 10:24:06 am »

Hi

Does anyone still have the kernel patch linux-2.4.6-rmk1-np2-embedix-20011228-sl5000d-20020318.gz ?

The links from http://sdjf.esmartdesign.com/kernel.html no longer work unfortunately.

C1000/3x00 General discussions / Zedialler?

« on: June 24, 2008, 12:07:57 pm »

Has anybody got the code for zedialler?

It's mentioned in https://www.oesf.org/forum/index.php?showtopic=16869 , and Ferret-Simpson says he got it working, but the link to http://externe.net/zaurus/modules.php no longer exists.

I would be interested to try it on my SL-C3100 now that I've got the RTM-8000 CF card working.

Thanks in advance

C1000/3x00 General discussions / Connect Directly To The Internet

Progress report as promised.

Success! I can connect to the internet directly from my SL-C3100 using the Audiovox RTM-8000 GSM/GPRS CF card. I am using a Vodafone (UK) "Pay As You Talk" SIM card.

I downloaded a file using ftp: 476980 bytes received in 88.6 secs (5.3 Kbytes/sec) which by my reckoning is ~42kbps. I understand that's slow by today's standards but I'm happy with it.

I can post details if anyone wants them, but most of it was following the How-To by tamarian referred to above.

I haven't got email working yet but that seems to be applications. I am not alone - see https://www.oesf.org/forum/index.php?&showtopic=14076. Any suggestions welcome.

zmiq2

Once again, thanks a lot for the information.

I have found an article on "GPRS in the UK", and I think I understand a little better now.

A couple of points.

It says that with GPRS, you pay for the amount of data transferred - not the time - so am I correct in thinking that a given file would take longer than the 3G option but cost the same?

I still use dial-up (56K) at home on my PC (not Broadband) and it suggests average GPRS speeds ~25-40kbps so it should only seem maybe half as slow as I'm used to - does that sound right?

I'm sure your suggestion that the Bluetooth option would be better overall is correct, but I think I'll have a go at getting the RTM-8000 working anyway.
I'll post the result - success or failure (but it might take me a while!)

Hi Dave,

your options are:

1) buy a CF modem to connect the zaurus to a fixed phone line

2) buy a CF Bluetooth card and a mobile phone with bluetooth tethering, and use the mobile phone as a modem to connect to the internet

3) buy a CF GSM/GPRS card to directly insert into the card your SIM card, and connect directly (but low speed) to the internet. Currently there are no 3G or 3.5G CF cards available; there was some talk about one being sold in Japan only, but it's very difficult to get and noones knows if it works wit a Zaurus.

4) buy a CF lan card to connect a rj45 wired ethernet cable and, through a proper router, connect to the internet

5) buy a CF wifi card and find am access point to connect to the internet


Some comments:
1) I understand you are looking for option 3. That is the most expensive option; one card is the most common: audiovox rtm-8000.
2) there is a lot of experience with having a bluetooth enabled phone; the phone can be a 3G or 3.5G phone, and you can easily get decent browsing speeds. I really think it's cheaper to get a cf-bluetooth card and a second-hand bluetooth enabled phone rather than a gsm-gprs cf card.
3) feel free to ask any further questions; many people in this forum have tried all different options. Connecting the Zaurus to the internet is the most wanted feature always

HTH

Thanks very much for the useful comments.

From having no options, I now seem to have too much choice (with too little knowledge), but I'm sure option 3 is what I need.

If I could get an Audiovox RTM-8000 for ~£30-40, why would the bluetooth solution be cheaper - are you saying the charges for browsing will be higher with GSM/GPRS? I am a real novice in this area. I notice you list the Audiovox card so do you use it on your Z? I do not require voice, SMS, etc. - I just want to occasionally check something online while out-and-about.

Thanks again for the time and help.

Dave

You probably could get a phone with no voice service. I don't know for sure.

I think that there was a discussion a while back about cellular network cards for the Z, but that they worked only in Japan or something.

Thanks for your response. I really want a solution not involving a mobile phone (I don't have one). I think the cellular network cards idea is what I'm looking for (but I know nothing about mobile communications) and things may have progressed (see my comments to InSearchOf's response).

I know there is a Audiovox GSM/GPRS card that is out... they are pretty old though and GSM/GPRS is SLOW!

Late

Thanks for your reply. I'm afraid I know very little about the various CF/SD cards available and nothing about mobile communications. I found some articles about an Audiovox card RTM-8000 and I am still digesting them, but from what I have seen so far, they are not cheap and no confirmed report that they work on a Zaurus. I only want to be able to access the internet occasionally when "out and about", so speed is not really an issue. I also found an article on Holux GM-270 with some references to the Zaurus so I am looking at that also.
I have now found a long thread about the RTM-8000 on this forum (https://www.oesf.org/forum/index.php?showtopic=1382&mode=threaded) with success stories for some models but failure on C3000 (interstate80). I'm becoming convinced this is the solution I need but would like to find a success story for the C3?00 models.
Since I added the above comments I have found a couple of these cards on eBay for ~£30 (I'm in the UK) so I might bid for one and give it a try. The next problem is getting a "data only" SIM card (I know nothing about them either!).

Hi

I have a SL-C3100 (Sharp ROM, Tetsu kernel).

Does anyone know of a way of connecting directly to the Internet - like a mobile phone without the voice part? Maybe a special CF card?

Thanks, DaveL

Could you clarify your question? You can get a CF modem card and use that to connect to an ISP. I remember seeing an entry in the old Zaurus Software Index to a program that allowed the Zaurus to connect directly to the internet through  DSL (without a router) but it seems to have disappeared.

Thanks for your reply. I want to be able to access the internet occasionally when "out and about". I'm afraid I know very little about the various CF/SD cards available and nothing about mobile communications. Am I correct in assuming a CF modem card connects to an ordinary telephone line? If so, this is not what I want - I have a PC at home for that. From the reply by InSearchOf, it sounds like I would require a GSM/GPRS card, so I am looking into that.
