Hi CodeRedSupport,
thanks for the super-fast reply! I really appreciate that.
Unfortunately, my problem persists.
-) The "USB Device with DFU Capabilities" shows up in the "Device Manager" no matter which port I use. This is good news.
-) When plugged into the back of my laptop (the "good" USB port) I can use any one of the three "Probes" to turn the device into a "LPC-Link Debug Probe v1.1" or into two "HID"-Interfaces. That works well.
-) However, when plugged into either one of the the USB ports at the side, my LPCXpresso shows up as "USB Device with DFU Capabilities"; but *neither one* of those three Probes show any effect. When started as:
[INDENT][FONT=Courier New][COLOR=Blue]DFUAPP /f LPCXpresso<XX>.enc /tl 250[/COLOR][/FONT]
[/INDENT][FONT=Courier New][COLOR=Blue] [/COLOR][/FONT]the Device Manager only briefly refreshes, but the LPCXpresso still shows up "USB Device with DFU Capabilities".
-) When experimenting with the timeout parameter (the "/tl" I assume?), as e.g. in
[INDENT][FONT=Courier New][COLOR=Blue]DFUAPP /f LPCXpresso<XX>.enc /tl 10000[/COLOR][/FONT]
[/INDENT][FONT=Courier New][COLOR=Blue] [/COLOR][/FONT]nothing changes except the Device Manager refreshes later (after around 10sec).
-) Yes, I have power-cycled (unplugged) the LPCXPresso after every trial!
-) Looking into the log file:
[INDENT][FONT=Courier New][COLOR=Blue]DFUAPP /f LPCXpressoFS.enc /tl 1000 /l l.txt[/COLOR][/FONT]
[FONT=Courier New][COLOR=Blue] type l.txt[/COLOR][/FONT]

[/COLOR][/FONT][/INDENT]So my computer downloads stuff, but only at the very end an error occurs.
Any further suggestions how to experiment with the "Probes" or other settings?
Thanks!
