Let's get started with a Pandora port

i was trying now about copying my old stuff to an
SD-Card. On the pandora it gave me allways errors,
no matter of which card-type, after copying more as 2GB.
at least the error appeated before i wrote 4Gb.
Now i tried with
an USB-Card-reader.
no Errors, could easily copy 12Gb.
but again, inside of the pandora, with sdfs instead
of scsifs(USB), Errors after 3GB.

So it’s either the SDFS, or it’s my Pandora.
Could someone please try if it works on his pandora to
copy more as 5Gb on an Sd-Card?

thanks

I can confirm this. When copying large amount of data (> 100MB?) via SDFS on ADFS-formatted card is used very often “broken direktory” error. After a reboot I continued copying …

For me it doesn’t work afterwards anymore, and i have a broken map (with check map)

is there another board using SD-Cards? (except the pandoraa)
on the BB-XM its usb-sticks.. The micro-SD-card is only for starting up Risc OS (rom)
on the Raspberry-pi the same, oly starting Risc OS, the boot-drive (adfs) is on USB-Stick

On the Pandora, i got only one USB-Port, therfore i need the SD-Card as ADFS-Drive.

Shall i report a bug? or shall i wait?

The RRi Distro has a two partition SDcard. A comparable System also works on the Pandora.
Look at my (under constuktion) http://riscos.openpandora.org
I mean the Problem are bigger (ADFS) cards. The second problem… the results of my Batch1 and Rebirth Pandora are not ever the same ;-(

For me it doesn’t work afterwards anymore, and i have a broken map (with check map)

Maybe an idea for a bounty – to build into RISC OS proper map/structure recovery and repair?

Before anybody asks, I’m not volunteering myself for two reasons:

1. I have not yet got my head around the E format zones thing as described in the PRM.
2. There are some things you absolutely do not play with without complete understanding. You write bad code and crash the computer, annoying but not world ending. Now tell that to somebody if you write bad code and trash their entire harddisc and everything on it (moreso if the data isn’t backed up).

Basically, I don’t believe I qualify to do filesystem stuff. But it would be nice idea for RISC OS to be able to fix itself like ScanDisk used to…

I tried using DD to write the image that I copied from my PC to the right SD card. Booting from it still resulted in the error I wrote earlier.I am abke to write to the FAT partition in Linux, so why is RISC OS telling me that its write-protected?

Sorry, you are the only one at this time with this problem. A other one in the “German Forum” have the same problem with Slackware. Please tell me your Angström Version.

v1.52 is what I’m using.

@Bryan Kirk
Please read the post in the other forum and your personal messages in it!
Many thanks.

I have (m)any problems. The most with my Batch 1 Pandora. The Rebirth it takes a little bit better.
Only under RISC OS! If I use the left slot I have many error… broken map, broken direktory, missing files and checkmap bring many errors. If I use the same card in the right slot or with a external reader… no problems, no errors…
If I use the left slot with Angström/Slackware… no problems.
Can you confir? Any ideas?

sorry, but its still confusing me, because it seems changed on
the pandora. left slot means the one with the adfs formatted card, true?
if so i can absolutely confirm. also the prob with the right nub and
that it sometimes gives only doubleclics, instead of singleclics (mouse), until reset.
i got somehow the impression, that sdfs pnly supports sd-cards up to 2Gb.
fear, noone had to use it before the pandora port…

I’m so sorry. Most I have the ADFS card in the right slot and in the left the Pandora stuff and boot, cmos and riscos in the FAT partition root. If you are using this one on the card in the left slot and in addition with the ROM you can take the ADFS card in the right slot. It works stable with my Batch1.

well i got your boot-image, running on the bootable
slot ‘sd1.1’(pandora bios-boot-selector) if i look
at the pandora from front its on the left side.
on the other slot i use the adfs formatted sd-card.
if i use it in an usb- cardreader there’s no problem,.
but if i use it in the pandora, i get an error, whenever i copy
a biger amount of files ( if the card contains more as 2..3gb
of files).

well i know, that the pandora port is still alpha.
so i just want to try and help to find out what works,
and what not. in the hope to get one day in the
future again a working computer with my favorite os: Risc OS.
because my RPCs got to big for my small flat with
children, i got no room for a desktop computer anymore..
so doing everything to get a netbook with RiscOS on it :-)

What Pandora you use? 256 or 512MB?
On my Batch 1 (256MB) the two card Version are working fine over 6 month. On my Rebirth (512MB) this or this works stable. Is RPi-like all in one autobooting for the left slot but the FAT Partiton is on the end of the card and the adfs one is at first. You need a 2GB card ore bigger. The .img.gz you can decompress with ArcFS and write the .img with !SDCreate or you use USBit with the .imz in Windows. If you try this

“Look for this line:

modprobe g_file_storage file=$device stall=0

and change it to:

modprobe g_file_storage file=$device stall=0 removable=1"

you can use your Pandora as cardreader with USBit. Set in Angström the SDStorage option.
With Ingos Batch1 and hit 1GHz Pandora the “One Card” ist working fine. May be the production toleranz is to big or they are problems with the cards.
Inside the “One card” ist USBDevSwp and !ComCentre (thanks to Thomas) to use a UMTS Stick… I have a Pandora Netbook ;-)

I hope you test this.

Do you know this? Is a answer from EvilDragon…

“… There seems to be some bug on the Pandora PCB (on all units). Quite a lot fail to detect the write-protection switch and will always set the SD Card as writeprotected, no matter what you do.

Therefore, this switch has been disabled in the normal Pandora kernel.

…

If you’re using your own kernel, then this switch should be disabled as well."

@Erich

If you play around with the pandorakey mouse settings (e.g. doubleclick delay down etc.) it takes a little bit better.
The problems seem to arise from a “resting shortcut”. [ESC] = [FN] + [Q] help sometimes.

Sorry it’s taken me a while to look at this. The latest ROM image should have a fix for the SD card being reported as read only (I’ve disabled the write protect detection)

So far I haven’t seen any problems with SD corruption on my Pandora (512MB Rebirth edition). I’ll try running a few test programs and see if I anything goes wrong.

@Jeffrey
No problem and many thanks.

Mostly, If the error is show I became a “broken directory” or “bad map space” via SDFS. If I use the same card after this with a cardreader… no errors, no problem.
With a little bit “luck” I became a “Disc error 08 at:1/000000036ADB8000” after restart or in a cardreader… no errors found. It look like a temporaly error. On my both Pandoras (Batch 1 and Rebirth) also with the new ROM.

Jeffrey you have a Pandora… look at http://boards.openpandora.org/index.php/forum/52-dragonbox-coding-competition/ and please vote… http://boards.openpandora.org/index.php/topic/12169-voting-applications/ ;-)
You can also look at http://riscos.openpandora.org … My new, under construction, Pandora WEB site. ;-)
If RISC OS win a price, I will donate this to ROOL!

Finally i could login again. seems windows7 and firefox doesn’t like the rool-website :-(
about my pandora: it’s a refurbished classic one, means an old classic-PCB in a rebirth-case
i will try again with the sd-card, as soon as i get some time again…
at the moment my family takes all my free-time…

At work I also use Windows 7 and Firefox (portable). No problem.

Interestingly, that Aemulor works at the 1GHz Pandora but not on the Batch1 and Rebirth.

My question:

Which type of USB to Ethernet adaptors are known to work with RISC OS (on the pandora)?

I use this one with my BBC4 and Pandora…

http://www.lindy.de/usb-2-fast-ethernet-adapter-10-100/42974.html

My question is: does it work out of the box with the Pi?

Sorry that this is not directly Pandora related.

Yes. With a little bit diffrent settings because the RPi has LAN on board.

No problem ;-)

Lindy seems delivers only to germany and austria, seems no way to get this in switzerland :-(
Seems i just have to try…
