Newbie startup questions - Windows SD formatting, serial port setup

Andrew Voelkel — 2013-06-19T03:29:24

Hi,

I am having a hard time bringing up my Pandaboard. I don't think at this
point that I have a HW problem, but it is a little to difficult to figure
out what is going on. I've got some questions, the answers to which might
help me get going.

1. Is it possible to format the SD card and install the Ubuntu image using
Windows? The help on the Pandaboard and Ubuntu sites makes it sound in one
place like this is possible, but in another place implies that the low
level SD formatting/partitioning is important, and only gives instructions
for Linux.. (Because I am using VirtualBox for Linux, I do not have access
to the SD card writer under Linux,  so I need  to use Windows for this).

2. Does the diagnostics SD image also require the complicated formatting
and partitioning that the Ubuntu image requires?

2. The help seems to imply that if you program the SD card improperly, you
have to go get a new SD card. Why? Can't you just reformat the SD card?

3. The serial port setup instructions are a little unclear. T

AIUI SVTRONICS are only one of a number of makers of the Pandaboard, though 
the others may also have or be planning to discontinue their Pandaboard.

SVTRONICS announced their Pandaboard replacement the OMAP5432 EVM a while 
back and it is in stock at:
https://www.svtronics.com/index.php?route=product/product&product_id=33

It is rather more expensive though:-(

Yes, you need a tool to write a bootable image. There are a number of them
out there,  type in "Windows tool bootable SD card" into the Google search
box and you will find several.

It is likely your SD card reader/writer is attached to your windows
computer via USB, if it is, and you are using VirtualBox then you can right
click on the 'devices' icon on your screen and then select the SD card
reader. This will switch it from Windows to the Virtual machine.  (FWIW
this is how I write my images to SD cards)

2. Does the diagnostics SD image also require the complicated formatting

Yes, all bootable SD cards need a partition map where the partition with
u-boot is bootable and active.



You can re-use the same SD card. Just re-format it.



No, all that is required is that Tx, Rx, and Gnd are connected correctly.
Depending on cables and hardware that might work out of the box, it might
require a null modem cable.



No. All the ones here do, but you can change the bootargs to set the port
parameters to whate

Ubuntu dist - why is it .raw instead of .img?

Andrew Voelkel — 2013-06-19T16:38:12

Hi,

I almost forgot another question to add to the ones below. When I go to the
prebuilt images for Ubuntu for the Pandaboard, download the .gz file, and
unzip it, the file inside has an extension of .raw. All the documentation
for programming SD cards indicates that I should be writing a .img file to
the SD card. What gives?

Dear All,
Received this from Digikey. Are Pandaboards really becoming obsolete?
Is there a replacement?

Call your local TI representative and ask.  Distributors of TI parts may be
able to help.
If you are not in the US it might be harder.   Letterhead and a tax number
may help, i.e.

Pandaboard ES Rev B2 Streaming issues with VLC

2013-06-17T15:54:39

Hi All,
I am trying to convert a UDP stream to an HTTP stream with a Pandaboard ES 
Rev B2. I'm using Ubuntu 12.04 and running vlc to do this with the 
following command:
vlc -vvv udp://< at >239.1.1.1:59001 --sout 
'#transcode{vcodec=WMV2,acodec=wma2,vb=200,scale=0.25,ab=128,channels=1,samplerate=44100}:standard{access=http,mux=asf,dst=:8080}'
 
The point is to scale down the stream and use the http stream to test the 
channel. I copied this command from another Pandaboard that we are using, 
and the command works on that one. I'm not sure if that one is a ES Rev B2 
though.
 
This command gives me the following errors:
 
[mpeg2video < at > 0xb520a540] invalid cbp at 46 10
[mpeg2video < at > 0xb520a540] invalid cbp at 62 15

Pandaboard-FreeRTOS Example with full RAM-Access from Cortex-M3. Pandaboard ES

Lars Rademacher — 2013-06-14T09:45:44

Hi,

i am trying to get full RAM access from one Cortex-M3 on my Pandaboard ES.

To achieve this, i used the Example-Code from 
https://github.com/apopple/Pandaboard-FreeRTOS .

I changed the loader.c as follows:

/* A program to ready one of the Cortex-M3 cores for execution */
So i changed the setup of MMU in order to get a linear mapping. Also i 
don't use the blink-Code but the M3 should just do busy waiting.

When the M3 is released from reset and watch what happens with Flyswatter2 
attached, i see that is double faults:

Error: omap4460.m30 -- clearing lockup after double fault

 I don't see what i am doing wrong.

Thanks in advance

Lars

OMAP 4460 low-volume availability

Mike Lewis — 2013-06-17T04:59:01

Hi, is the OMAP4460 available for purchase in low-volume (100-300 
units)? I'm having trouble finding any OMAP4-series units available from 
3rd-party distributors. Odd, since from the low-cost of the PandaBoard I 
would think TI would make them available to small customers.

OMAP44xx low-volume availability

Mike Lewis — 2013-06-17T05:27:36

Hi,
Is it possible to purchase OMAP44xx units in low-volume (100-300 units)? 
I've tried to find it via 3rd-party distributors but have had no such luck. 
And it's odd since the low-cost of the Pandaboard should suggest that TI 
would make it available to small customers. I'd like to develop a custom 
board that supports stereo cameras and this is the only applications 
processor that seem(ed) attainable.
