Well, while i am researching how to make this board work with FreeBSD, i have stumbled upon new issue.
Following the info at this link: http://support.code-red-tech.com/CodeRedWiki/LPCLinkDiagnostics

First of all, the lsusb shows this:

Bus /dev/usb Device /dev/ugen6.3: ID 0471:df55 Philips

While Downloading the firmware to LPC-LINK by:

dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc

I end up with this:

Opening USB Device 0x0000:0x0000...
Claiming USB DFU Runtime Interface...
Determining device status: state = dfuIDLE, status = 0
WARNING: Runtime device already in DFU state ?!?

After doing lsusb again, the previous Philips device is gone and new thing appears

Oh how i wish code red would share libLPC_Link.so sources, but probably wont happen.
Time to start reversing :D

Good luck.

As I have mentioned in another thread, there is information from inside of NXP that a new, open version of LPC-Link is in preparation. Maybe it's worth drilling deeper into it with NXP.
I'm using mostly Crossworks anyway, because I need support for other, non-NXP controllers, too. Up to now, this also means discarding the lpc-link there - unfortunately...

Well, i am working on temporary hack for now. Need to write replacement for libusb-1.0 shipped with the lpcxpresso (inside lpcxpresso/bin dir) and it might work. libLPC-link relies heavily on this shared lib.

libLPC_Link is full of stubs:
CR_ResetDevice
CR_Purge
CR_SetTimeouts
CR_GetStatus
CR_GetBitMode
CR_SetUSBParameters

All those are stubs - return(0) kind of. (CR = CodeRed i guess lol)

Almost done reversing libLPC_Link. (Had stuff to attend to and not much free time)
From what i saw, It looks like this lib is a product of copy/paste from libusb tutorials.
It has some useless rudiments and inconsistency in useless error printing, Obsolete function arguments (like function prototype supposed to take 3 args but none of them are used inside the function body). error printing sometimes is done to stderr using fwrite and sometimes to stdout using puts. Probably someone outsorced the coding of this lib :D

Anyway, soon i will release opensource version of it. Hope no trouble will come as a result lol.:eek:

This seems like a lot of effort, when LPCXpresso 'just works' on Linux. What is special/different about FreeBSD compared with Linux (I don't know myself). what is the point of doing this? How are you going to keep it in step with what Code Red do? Just curious.

Well, linux was my OS of choice for about 15 last years, i have tried multiple distros (RH, DEBIAN, SLACK, LFS, GENTOO) and my favourite so far was gentoo. I have moved to FreeBSD just recently, because i felt like making a change and learning something new. And actually, the "feel" that i get from FreeBSD is the best "feel" i ever had from OS. Though, i constantly run a gentoo instance in virtualbox. The fun is in seeing the differences and similarities between the both OSes. I am porting lpcxpresso to FreeBSD for educational reasons (And another reason is because Ubuntu annoys me :D)

@Gogamoga....Hi...!!!

Is your BSD working with LPCxresso.
Try UBUNTU10.
It may help you.

Thanks & Regards...:)

@Gogamoga....Hi...!!!
Try UBUNTU10.

I cant stand ubuntu, it works on gentoo though, and gentoo is my fav distro,
But i am not planning to move away from FreeBSD and definitely not planning to run lpcxpresso in virtualbox.

Anyway, the most of work is done. all that is left to do is make RPC wrapper for libLPC_Link (which is peanuts compared to what i have done already :P)
and everything will work. Besides, as the side effect of the wrapper, it will be possible to remote-debug the board - even if its not connected to your machine directly :P

PS.
My parents lately asked to kick the windows out from their laptop and put linux in. They are senior people, and transition to other OS could be hard for them, even though, i will not let them experience the damn ubuntu. PCBSD is a way to go :P

@Gogamoga....Hi...!!

OK....I understood your concern.

Can you share your code and idea what exactly you are trying to do.

Thanks & Regards.....:)

By the end of the week i will release the full source for the libLPC-Link.
Its just not ready yet - have to attend to my primary work, so not much time to mess with reversing. Check on this thread by the end of the week. There will be full sources and examples ready by then (I hope)

Awesome work and congratulations. Looking forward to seeing your work. I agree, FreeBSD is an amazing os and definitely doesn't get enough credit. I first installed FreeBSD back in 2000 and was amazed at how fluid the os felt in comparison to current Linux distros at the time. Specifically regarding the installation of the OS over a dial up link (lol)

FLUID - THERE, Exact word i was looking for to explain the feel i get from the FreeBSD :)
Its just that - fluid - no jumpy feeling that i get from linux - no peaks and falls

PS.
Hardest part with libLPC-Link so far, is figuring out how to name the members of the packet structure used to send data lmao :P
