1  General Category / General Discussion / Re: Minix 3 to Arm port. on: July 21, 2009, 06:34:49 PM
I know I'm reopening an old topic, but I would be interested in an ARM port of Minix. Smiley

I would investigate this line:
usb 7-2: Ignoring serial port reserved for JTAG

There's probably some new method for accessing JTAG that was added in the new kernel or something. It knows it's there, it just won't use it as a serial console.

A quick google shows that if you really want to access JTAG, you should investigate openocd. The serial driver was revised so it doesn't treat JTAG interfaces as serial consoles.

Ok, thanks. I was just wondering why it was showing one ttyUSB instead of two. If I need JTAG, I will use OpenOCD. Smiley

I am trying to access my sheevaplug as shown on here and here. Neither of those seem to help, as I always only get one serial interface. I even tried rmmod'ing and then modprobing ftdi_sio, and that didn't help. Here is what dmesg says about the sheevaplug after I put it in:

usb 7-2: new full speed USB device using uhci_hcd and address 6
usb 7-2: configuration #1 chosen from 1 choice
usb 7-2: Ignoring serial port reserved for JTAG
ftdi_sio 7-2:1.1: FTDI USB Serial Device converter detected
usb 7-2: Detected FT2232C
usb 7-2: FTDI USB Serial Device converter now attached to ttyUSB0

It seems like it is ignoring the jtag interface? I am on Arch Linux with the most up-to-date stuff in the stable repositories (testing not enabled).

EDIT: I tested it with GtkTerm, and in fact I am able to get the uBoot message. So for some reason it hates the jTag.

Ordered mine on May 25th, shipped July 14th, arrived July 17th. Smiley
5  Linux Stuff / General Linux questions / Re: Getting Started with the cross compiler on: July 15, 2009, 02:33:12 PM

Hoping you can help me through getting set up with the MIMO monitor.

This is really more of a question for getting the toolchains working correctly, I guess.

I have the cross compiler working... able to compile my simple HelloWorld programs no problem.

I've downloaded, untarred/unzipped the xf86-video-displaylink and the attachment.c pointed to in your previous post.

I set up my PATH to point to the gcc instance: ./gcc/arm-none-linux-gnueabi/bin/gcc, located in my home directory.

I run sudo ./configure --build=i386-linux --host=arm-linux

Looks like the script is happy until:

No package 'xorg-server' found
No package 'fontsproto' found

Figured I'd ask how to proceed...


You need to install the xserver-xorg-dev package. With any luck, the fontsproto dependency will also be taken care of with that (I couldn't find fontsproto in any package search).

One thing I know exists that lots of other people use (especially people within enterprise environments) is Asterisk, and since it is open source, you should only need to recompile it for ARM to get it to work.
7  Hardware and U-Boot firmware / Hardware / Re: SheevaPlug v2 - Hardware Requests on: June 23, 2009, 09:41:24 AM
A couple of us SheevaPlug owners were discussing the Plug over lunch yesterday, and I made the same comment -- that a Gig of memory would be nice.  One of the other guys pointed out that he thought the Marvel chip only brought out 30 bits of address:  30 bits == 1 GB of addressable memory, so with 1/2 GB of RAM and 1/2 GB of NAND, they appear to be maxed out.

Well, according to the specs (since I don't have mine yet, I can't tell) you should be able to reuse a NAND flash module from most common USB Flash drives to increase the internal memory, and as for RAM isn't it just normal DDR2 RAM like they use in netbook computers? If so you can probably find a bigger stick online.

Ah thanks, I found what you were talking about here in the reference design. It seems that it is limited to 512 DDR2 memory, but the flash itself isn't limited to what its got. Just got to make sure the connection is the right one. Smiley

I think the sheevaplug is limited to 512 NAND and 512 RAM, however I am not completely sure.

So it is a BIOS limitation then?
10  Hardware and U-Boot firmware / Hardware / Could I upgrade internal NAND flash with one extracted from USB key? on: May 26, 2009, 06:29:54 PM
I already ordered my Sheevaplug, but am just wondering. I know that the Sheevaplug uses a NAND flash drive for internal storage, and that many USB keys use the same type of interface. My question is whether an extracted one could be used to "upgrade" the sheevaplug, ie if I could take my 1GB usb key apart, extract the drive, and sauder/plug it in.
