LPC-Link doesn't start from Virtualbox

Hi,

I'm using Windows XP under Virtualbox from Linux. I have no problem with the red probe from the RDB1768 kit but can't get the LPC-link working.

Following a forum post, I did a few investigations and here's what I get:
- "USB Device with DFU capabilities" detected correctly
- either LPCXpresso or DFUAPP start downloading stuff but LPC-Link never initializes correctly, meaning that I never see anything else than "USB Device with DFU capabilities". Even lsusb from the linux kernel doesn't see the 3 devices that should initialize, which means LPC_link is never restarted with the new code.

Below is the log from DFUAPP download. It seems the firmware isn't transfered correctly.

Anything else I can try? Would you have another driver for me to try?

Thank you,
David

I got it working now. Basically you need to:

[LIST=1]
[*]Enable USB 2.0 EHCI mode
[*]Start debugging, LPC-Link will start and timeout
[*]Quit LPCXpresso, shutdown VirtualBox
[*]Linux will now enumerate the Red Probe correctly
[*]Restart VirtualBox and LPCXpresso
[/LIST]
Each time, you need to select the correct device from the USB device list of course, or like said before, add them in the configuration of the VM.

Hope that helps

David

Thnak you. I now enabled the USB 2.0 mode which was disabled and it seems the LPC-link likes it better as it goes further but it still doesn't work. From the log, it looks like the device is programmed completely now but doesn't restart. I even tried a manual reset by shorting C22 but still no enumeration of the expected devices.

Here's the log of dfuapp:

Hi,

I am using VirtualBox under Windows. Problem is that board is enumerated as a 2 devices. I added both of them.

Have look at my configuration file:

<USBController enabled="true" enabledEhci="true">
        <DeviceFilter name="Code Red Technologies LPC-Link Probe v1.1 [0100]" active="true" vendorId="1fc9" productId="0009" revision="0100" manufacturer="Code Red Technologies" product="LPC-Link Probe v1.1" remote="no"/>
        <DeviceFilter name="Unknown device 0471:DF55 [0001]" active="true" vendorId="0471" productId="df55" revision="0001" remote="no"/>
      </USBController>

I never had any other problems with Virtualbox under Linux. As I said, code-red probe works perfectly with LPCXpresso.

Now using libusb, I'm pretty sure the LPC-Link never restarts with the downloaded firmware. I can't myself check from the log I attached if all the firmware is downloaded correctly.

---> DFUStatus: Received DFU_DNLOAD with wLength = 0, but device does not think it has all of the data yet.
---> DFUState: An error has occurred. Awaiting the DFU_CLRSTATUS request.

This seems to indicate that the download didn't complete.

There are no other drivers.
It sounds like Virtual Box on Linux doesn't support USB correctly.

After you get this error, does the LPC-Link boot anyway?
