Hello,
I am trying to load a bootloader on my LPC (NXP) microcontroller. I have installed
LPCScrypt<https://www.nxp.com/design/microcontrollers-developer-resource…
and am using a script for it called boot_lpcscrypt.cmd where I call dfu-util -l in order
to check if an NXP device in DFU mode is connected. I have it working on many computers
but on multiple computers I get the following when I call dfu-util -l:
C:\path\LPCScrypt>dfu-util.exe -l
dfu-util 0.7

dfu-util@lists.gnumonks.org<mailto:dfu-util@lists.gnumonks.org>
Found Runtime: [1fc9:000c] devnum=0, cfg=1, intf=0, alt=0, name="DFU"
Found Runtime: [1fc9:000c] devnum=0, cfg=1, intf=0, alt=0, name="UNDEFINED"
which means I cannot boot my image with the following command:
C:\path\LPCScrypt>dfu-util.exe -d 0x1fc9:c -c 0 -i 0 -t 2048 -R -D
"LPCScrypt_140.bin.hdr"
More than one DFU capable USB device found, you might try `--list' and then disconnect
all but one device
I then did a dfu-util -l -vvv for verbose output which gave me the following log:
C:\path\LPCScrypt>dfu-util -l -vvv
dfu-util 0.7

I find the following lines to be interessant:
libusbx: debug [init_device] (bus: 1, addr: 34, depth: 1, port: 4):
'\\.\USB#VID_1FC9&PID_000C#ABCD'
libusbx: debug [init_device] (bus: 1, addr: 34, depth: 1, port: 4):
'\\.\USB#VID_0B0E&PID_245D&MI_03#6&2C280BB0&0&0003'
because USB#VID_1FC9&PID_000C#ABCD is my NXP microcontroller in DFU mode and I think
USB#VID_0B0E&PID_245D&MI_03 is a Jabra Headset and for some reason they share the
same configuration bus: 1, addr: 34, depth: 1, port: 4. Notice, that these are actually 2
different devices on 2 different USB ports.
Then, from my understanding, dfu-util tries to open those devices with libusb_open, it
works for USB#VID_1FC9&PID_000C#ABCD because it is in DFU mode:
libusbx: debug [libusb_open] open 1.34
...
Found Runtime: [1fc9:000c] devnum=0, cfg=1, intf=0, alt=0, name="DFU"
but not with USB#VID_0B0E&PID_245D&MI_03, which is a headset in normal mode. The
output is:
libusbx: debug [libusb_open] open 1.34
libusbx: debug [unsupported_open] unsupported API call for 'open' (unrecognized
device driver)
libusbx: debug [libusb_open] open 1.34 returns -12
I have 2 questions:
1. Shouldn't the output be corrected to give the correct VID:PID? to something
like:
Found Runtime: [0B0E:245D] devnum=0, cfg=1, intf=0, alt=0, name="UNDEFINED"
2. Is it correct, that USB#VID_1FC9&PID_000C#ABCD and
USB#VID_0B0E&PID_245D&MI_03 share the same configuration bus: 1, addr: 34, depth:
1, port: 4 even though they are 2 different USB devices on 2 different USB ports? Is it a
problem with dfu-util or with Windows? Can I fix this?
Many thanks,
Mit freundlichen Grüßen
