Olimex arm-usb-ocd linux virtual serial port kernel 2.6.x

I don’t know if anyone else has tried to use the arm-usb-ocd serial port on a linux 2.6.x kernel using the ftdi_sio.o driver but it will not work since the Olimex id is not in the ftdi_sio product/vendor list. The ftdi_sio.o must be recompiled with the following changes:

ftdi_sio.h

/* put the following before the Commands area */

#define OLIMEX_ARM_USB_OCD_VID 0x15BA

#define OLIMEX_ARM_USB_OCD_PID 0x0003

ftdi_sio.c

/* put the following after the last VID/PID entry in the struct usb_device_id id_table_combined */

{ USB_DEVICE(OLIMEX_ARM_USB_OCD_VID,OLIMEX_ARM_USB_OCD_PID) },

after saving the changes, recompile the module and it should allow the OLIMEX ARM_USB_OCD device.

Thanks a LOT!

I’ve tried to do this myself but didn’t manage to get it to work.

However, I the driver claims both channels, and only the B channel is connected to RS232 levelshifters.

Do you think it would be possible to use openocd on channel 1 and the ftdi uart driver on channel B at once? (I estimate the chance to be very low)
