Is this the Beagle board you're referring to ?
If so, are you happy with it ? I've been considering getting Beagle,

I'm not sure about Linux (and am curious) but in C this is defined by the
heap size.
The heap normally is located between the end of (i)data and the lowest the
stack(s) can/might go (assuming a full descending stack).
This is decided at link time and is runtime constant.
Also note that - regardles

I haven't used ftrace yet, but from using commercial RTOSs on

"RUNNABLE".

That will be hard. You could rely on a free running timer, but then you are
tied to variations in HW again.

I'm a Linux kernel newbie, (although I have heavy embedded MCU coding
background) but I can help with the general approach of this scenario.
First, it's important to note that any interrupt

But that's not part of the ANSI file I/O. I gave this as a caveat.
I'm not familiar with this nonseekable option (and I can't actually see the
benefit of it in a proper file stream).
But you did specify use of your own char device driver - I think.
Perhaps yo
I presume that llseek results from a seek() call ?
A seek() call implies (to me) the use of higher layer file I/O streams.
I don't think there's a way to inhibit the high level library from wanting
to call seek().
Also, note that some specific fread()/fwrite() sequences need a flush, or
at least a
On a first approach these might help :
1.
To make sure that you're talking to the adapter type 'ifconfig'.
Any wlanX devices already installed or eth0, disable them with :
ifconfig down - where is eth0 and so on.
Do this until you only have 'lo' left in ifconfig
then activate your PCI
Hi,
I can't say 100% for sure your enumeration is broken, but it certainly
seems that way.
Before you debug too deep into the ECM or ACM side of your CDC, try using
USB Snoopy or some such on the enum process.
1. How can I ascertain that the enumeration has happened properly?
