Problems With Usb Host

[PokeParadox]

Well here's the deal... I have modded my TV-out cable into a longer S-Video, composite and powered USB host. The mod was a success and I can use s-Video composite, and I have tried an USB mouse on Quake, and a joystick on the joytest that was released it all works!

What doesn't work is the ext option in the GP2X menu. the hard disk appears to be detected and installed... but it's not being mounted, or setup for access properly, as in I can't browse it in the ext option... I have tried with both my iPod video and an external USB drive I have.

any idea what the problem could be?

PS: I have also tried reflashing the 2.00 firmware... but for some bizarre reason my SD card won't flash the GP2X anymore... *sigh* I figure some setting has become invalid relating to ext drives... and reflashing was my attempt a fixing this.
When the USB network feature was added, I tried mapping a shared folder on my pc to the ext option... I never got this working either... this makes me think that it is related to the current problem.

 

[PokeParadox]

sorry, but *BUMP*

And I managed to reflash the firmware (I am a tool.. I forgot that in FW 2.0 you have to hold Start and Select!! >_>) but still I can't see the usb disk... how would I manually mount it or whatever just so I can access it?

I've had this very problem. If I telnetted into the 2x I could see the sda in the dev folder, but it wasn't getting mounted as EXT.
In the end I wrote gpu script to mount it for me once I'd started the USB host up.
My 2x unit has just been returned today, so I'll be trying it again shortly, see if there's any difference.

To mount it manually I used this script:

mount -t vfat /dev/sda1 /mnt/ext

Assuming it is in the "dev" folder as "sda1" and formatted as FAT or FAT32 it'll come up as EXT! (I hope!)

 

[PokeParadox]

Thanks! I'll give that script a go! If it works... you win... appreciation...
meh it's about all I can afford, but yeah I'll be grateful if this works.

 

[BenScar]

Just tested my new 2x and I needed to Telnet into it first, cd into mnt and "mkdir ext" before that script would work.

Might have bew why it's not appearing when the USB Storage is turned on (although I've only just though about that and I have ironing to do now!)

"appreciation" is all that's needed

 

[PokeParadox]

Well... you don't even get appreciation.... *spit* it didn't work! </joking>

Hmmm... I have noticed that the following appears in /dev/ when the drive is plugged in:

sd
sda
sda1

I'm assuming this is standard linux behavior for handling removable drives (I'm not very linux literate, unfortunately)

I've tried mounting each of these in telnet, like your script mentions (no idea if it is correct) but each time I get "invalid arguement"

I know there is a ext directory, so that's not the problem...

I also create a gpu script out of the er... script, but still nothing appears in ext... :/

Any other ideas?

/me has a sad face on....
Will work on this then

sd
sda
sda1

You and me both, Linux is not something I have a great deal of experience with (the 2x being the bulk of it at the moment, there is an Ubuntu installer CD waiting for me when I get the chance!

Edit: seems I wasn't to post that the first time, blue screened when I hit post! All the more reason to get Linux up and running!

I've tried mounting each of these in telnet, like your script mentions (no idea if it is correct) but each time I get "invalid arguement"

I know there is a ext directory, so that's not the problem...

When you say you know it exists, what do you mean?
Can you see it when you "ls" the "mnt" directory?
Although I could see it though the interface I didn't see it in the directory when I "ls"ed it.

I also create a gpu script out of the er... script, but still nothing appears in ext... :/

Any other ideas?

Strange, I thought it would have worked.
No other ideas springing to mind at the moment, but then it is 11:30pm and my mind is rather fuzzy..

Yes what I meant was, I telnetted to the ext directory and it is there when I type "ls".

This is sooo frustrating... knowing my cable mod works, but not being able to use my hard disk... although I have realised why my other external disc won't work... It's NTFS format... Still doesn't explain why the iPod won't mount though :/ (that is definitely FAT32 ...) I may try mounting my grandad's MP3 player as a drive... just to see if it's being piccy about the device.

Linux lesson!

When you plug in an external HDD, Linux puts it and its partitions in /dev, like so:

/dev/sda - Drive
/dev/sda1 - First Partition
/dev/sda2 - Second Partition, etc.

If you have only one partition, then you want to mount /dev/sda1.

Invalid argument errors are generally caused by unrecognised arguments after options such as -t. Try removing "-t vfat" and getting mount to autodetect the filesystem.

 

[PokeParadox]

Well I tried removing the -t command and still it says invalid args...
I borrowed a USB stick from my grandad, and a card reader.... and these were detected ok.. so the problem is with the iPod it seems...

 

[nickspoon]

Is your iPod using HFS+?

 

[PokeParadox]

Nope, it's FAT32. It's also an iPod 5G (iPod Video 30GB)

Yay, at least you know everything works and it's pinned down where the problem is.
So the USB stick and card reader were detected OK, did they auto mount to the EXT folder though the interface?

Shame about the IPod though...

 

[PokeParadox]

Yup they auto mounted... I did a bit of googling and I found this:

http://ipodlinux.org/Mounting_on_Linux

Which seems to me like I need a couple of modules... in order to get this working... so where would I get some ARM-Linux modules? :S

uhci_hcd <-- that more specifically

it also mentions: sbp2
but I think that this is for firewire.

 

[nickspoon]

Type 'lsmod' in a terminal (with your USB HDD connected and USB storage enabled in the menu) and post the output.

Also, what appears in /dev when your iPod is plugged in?

I tried to connect to the ipod a while ago. See this topic:

http://www.gp32x.de/board/index.php?showt...640&hl=ipod

I still cannot connect
