Programming .hex files onto LPC2148 via USB interface - /dev/ttyACM0
by Saleem Ansari
Hi!
I have a LPC2148 based board which has a USB port. When I connect it
to my laptop following messages are displayed:
[32729.410099] usb 3-1: new full speed USB device using uhci_hcd and address 14
[32729.562243] usb 3-1: New USB device found, idVendor=ffff, idProduct=0007
[32729.562255] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[32729.562263] usb 3-1: Product: USBSerial
[32729.562268] usb 3-1: Manufacturer: LPCUSB
[32729.562273] usb 3-1: SerialNumber: DEADC0DE
[32729.566355] cdc_acm 3-1:1.0: This device cannot do calls on its
own. It is not a modem.
[32729.566422] cdc_acm 3-1:1.0: ttyACM0: USB ACM device
while the device file is correctly configured as:
$ ls -l /dev/ttyA*
crw-rw----. 1 root dialout 166, 0 Nov 1 18:48 /dev/ttyACM0
I am using Fedora 14 - 2.6.35.6-45.fc14.x86_64.
I tried to upload the code to this device using minicom ( as described
in this page http://docwiki.gumstix.org/index.php/Connecting_via_Serial_-_Linux
)
( note that this device is not /dev/ttyS0, its /dev/ttyACM0 and i
dont know if it really matters )
I switched to ISP mode and sent a .hex file, but it doesn't seem to be working.
I do know that we can program it using lpc21isp (
http://lpc21isp.sourceforge.net/ ) over serial port ( /dev/ttyS0 etc.
).
However I want to know if it can be done done via USB port. Any ideas
about how I can upload the .hex files ( or maybe the .bin files for
that matter ) using the USB port?
( excuse me for my ignorance on this )
Any pointers will be highly appreciated.
Best regards,

Mine is on order, with specific intent to use the WLAN so this thread has my full attention. More than happy to pitch in once mine comes in.
