LPC based core not loading code

[sparx]

I've just finished building an LPC core board, installed the software, flashed the device etc.

Start up MIOS Studio 2.2 and try to load an application in and it stops, sometimes at 13% other apps at 39%, whole thing fails after 16 retries.

Anyone had this? Or any idea how to solve it?

TIA

Which operating system are you using?

How is the core powered?

Does it also happen if your are booting the core in BSL Hold mode (J27 jumper stuffed)

Does it also happen when you are using an USB hub with external PSU, or if you power the core via J1 (remove J17 jumper in this case)

Best Regards, Thorsten.

* XP

* via USB

Yes, it's XP.

Have tried to power the core with both USB and external supply, same result.

LED glows on LPC board so it seems to be getting the messages from MIOS Studio.

Same result in BSL Hold mode.

Any ideas?

Thanks

Could you please try it on a different computer?

This would be important to get an understanding if the issue is related to the computer itself, or to the core module.

Tried it on a different computer and the same thing. Only constant was the MIDI interface which has been used before with no problems.

I'm stumped so do appreciate any help.

Thanks again.

Why would you use a MIDI interface anyways? Connect the LPC baseboard directly via USB and you're set. Unless I did not understand your setup properly, which is probably the case because the facts you give are very sparse...

I guess that he tries to use the USB interface, but the upload fails.

And it seems that it doesn't fail with a common MIDI interface (this was a helpful test)

Sparx: could you please try this new bootloader version v1.006:

I increased the buffer sizes, and a helpful debug message is print if less bytes are received than expected.

Is the upload working with this version?

Are messages print in the MIOS Terminal? (if yes: which ones exactly?)

Best Regards, Thorsten.

Thank you!!

All up and running now.

Wow, really!?! :)

This was a "blind" change without testing on a WinXP computer, I'm glad that this solves the issue :)
