First Impressions: LPCXpresso Linux

Hello all,

My impressions are very good for LPCXpresso in Linux. I use Mandriva (which is a species in danger of extinction :) ).

Everything is installed fine, and compiles the programs without problem, but with the same problems in Windows when it comes to debugging: the driver is not loaded.

Then, as if by magic works, but may change his mind, everything depends on the mood of LPCXpresso.

I registered my copy with no problems, but "Program Flash" does not work, I have exactly the same error as discussed here.

We look forward recommendations to resolve the intermittent problem of drivers.

Thank you.

Hi,

I'm sorry, but Mandriva is not one of the supported platforms, so we cannot offer much help for you. We specifically list the distros we support as (unfortunately) not all distros are not created equal - as you have found.

The screenshot you supply is *not* an error. It indicates that the board was successfully booted. I suspect the error is because we are unable to detect the board after it has booted. Does your system have the command line tool lsusb? If so, after the board has booted, can you run the command and post the output? If not, that is your problem...

You also mention that "program flash does not work" and mention you have "exactly the same problem" as listed in a thread. Unfortunately, that is a *long* thread with lots of things discussed, so perhaps you can be more explicit and explain what the problem is.

Thanks

I have it working pretty well on OpenSUSE, including the debugger. The only problem I've discovered is that the New Project wizard does not work. After asking for name, directory, target, etc. it gives the error "Unable to create project 'xxx'". I created a project manually, so I have a workaround for now.

Hi,

Thanks for the informtion. Could you zip up and post the <workspace>/.metadata/.log file? This will help us identify why the project wizard doesn't work.

Also, have you tried all the wizrdas, or just one? If one, which one?

Thanks.

I mean the part that says: "03:failed on chip setup:Ec(01). Invalid, mismatched or unknown part"

But I discovered that the problems of debugging and programming of the memory are the same: Driver "usbfs" not loaded.

lsusb shows:
before

Bus 001 Device 004: ID 0471:df55 Philips

and after

Bus 001 Device 005: ID 1fc9:0009

I discovered that when it fails is because the driver "usbfs" is not loaded:

Data obtained from the file: /proc/bus/usb/devices

I also discovered that the option "Program Flash" is the cause of the malfunction. After using this function LPCXpresso not debug.

I'll just paste in the relevant section of the log, since it is short enough:

!ENTRY org.eclipse.ui.browser 2 0 2010-09-20 16:59:46.623

!ENTRY com.crt.quickstart 4 -1 2010-09-20 17:00:05.207
!MESSAGE Unable to create project 't2'

I tried setting the following variables, but it did not fix the problem:

export MOZILLA_FIVE_HOME=/usr/lib64/xulrunner-1.9.2.10
export LD_LIBRARY_PATH=/usr/lib64/xulrunner-1.9.2.10

All of the other wizards I've tried appear to work. Thanks for looking into this.

drunnell,

The small section of the log file that you posted is showing two different issues, and has nothing to do with why the New Project Wizard is not working.

Can you please post the whole log file.

Luis Digital,

I am sorry, but as mentioned at the start, we do not support your Linux distribution. It appears that your distribution does not come pre-configured with the all the required USB drivers/components.

Best Regards,

Luis Digital,

The usb drivers we use require that usbfs is installed. See
http://www.linux-usb.org/USB-guide/x173.html
for information. If you can find a way for your Linux distribution to install usbfs, then you stand a good chance of making progress. We are unable to help with finding and installing usbfs for you.

Best Regards,

I explained that sometimes I can debug, and sometimes the driver "usbfs" is loaded with no problems. The problem is that sometimes LPCXpresso has flaws, then the problems begin with the drivers. But forget all the above, Mandriva is a distribution dying.

I would propose that offer support for [COLOR=Red][B]OpenSuse[/B][/COLOR], have reported to run smoothly, and is one of the most widely used distributions.

Ubuntu is widely used, but not exactly among people who program microcontrollers.

Moreover, the experience can serve to provide commercial service to customers who prefer Linux.

Thank you very much.

If you follow the other posts, you will see that somebody else has reported that LPCXpresso is running on OpenSuse (with a small incompatibility, that we are investigating).

I would be interested to know where you get your data from, to be able to state "Ubuntu is widely used, but not exactly among people who program microcontrollers."...

Ubuntu is "sold" as a product for people who have little experience with computers / Linux.

It is the most used, but usually by new people.

I am an experienced user that prefers Ubuntu mainly because it is "easy".

It is perfectly suited for embedded development, the repository contains almost everything, including things like Eclipse, CodeBlocks and OpenOCD, not exactly tools for unexperienced people.

The ease of use of Ubuntu is a myth, for example:

Early versions did not have a graphical installer, when all other distributions did have one.

These are sterile discussions, pointless, but I worry that CodeRed / NXP give support to a given distribution, not Linux, as it should be.

If tomorrow the fashion is "Linux for Christians" what with all the work dedicated to a single distribution?

All we have to use "Linux for Christians"? And what about the atheists?:p

So, it is a myth because early versions did not have a graphical installer (how many years ago? six?).
Right now it can go from a naked laptop to a functioning Eclipse based ARM IDE in less than 30 minutes, that makes it perfectly suited for my embedded development needs. Being "popular" almost ensures that everything available for Linux has been tested on Ubuntu too, not a small advantage.

Sorry for the off topic :-)

I have to ask - why are there so many Linus distros? www.distrowatch.com lists the top 100!!!

<rant>
I just cannot understand why there are so many. Surely if all those people wasting their time producing slightly different variations of the same thing, actually spent it on improving ONE version, then Linux might finally live up to its promise and replace Windows.

I am an experienced developer and first used UNIX (actually, it was Xenix) in 1985, and have used various flavors ever since. Of recent distros, I have used Ubuntu, Fedora, SUSE, and Centos. I think Ubuntu is the best of the current crop, with OpenSUSE close behind.

I don't understand this macho attitude of thinking that developers like to do it the 'hard way'. The OS is a tool that I use to do my job. I want the tool to be as easy to use (and quick to setup) as possible and not get in the way. Ubuntu does that for me, even if some die-hards think it is for 'consumers'.

There are many distributions because everyone is free to create one. I like the easy to me as well, so I prefer Mandriva or openSUSE (formerly SuSE Linux). My past experiences with Ubuntu are not good, especially supporting some hardware. Ubuntu has very little packaged software on your CD / DVD, and that is another problem because we do not have fast connections to be downloaded each time a package.

LPCXpresso is working very well in Mandriva, the only problem is that the first time the process of debugging does not work, I can not use the function "Program Flash" because when it ends I can not debug either.

Had similar problems in Windows, so I think LPCXpresso has some flaws.

I have the same problem here. CodeRed apparently has not solved the problem in Beta 2.

And not a fault of Mandriva or openSUSE, is LPCXpresso failure because eclipse from eclipse.org works well.

Thanks.

Opensuse is not officially supported.

However we beta2 works correctly here on latest version of that distro. Perhaps you can provide some details about what is not working and we might stand a chance of understanding if there is an issue. Provide full details rather than letting us guess what might be wrong.
