I'm not a skilled programmer so please bare with me if the solution to this is trivial... I tried to build a "Device Firmwire Upgrade gadget" on a beagle target, but a build error occured: drivers/built-in.o: In function `usb_composite_unregister': dfu.c:(.text.usb_composite_unregister+0x14): undefined reference to `usb_gadget_unregister_driver' drivers/built-in.o: In function `usb_composite_register': dfu.c:(.text.usb_composite_register+0x54): undefined reference to `usb_gadget_register_driver' drivers/built-in.o: In function `usb_dfu_register': dfu.c:(.text.usb_dfu_register+0x4c): undefined reference to `usb_gadget_poll' I also tried to build (with the experimental code flag set) USB_GADGET_SERIAL, but it failed in a similar way: drivers/built-in.o: In function `usb_composite_register': f_acm.c:(.text.usb_composite_register+0x54): undefined reference to `usb_gadget_register_driver' drivers/built-in.o: In function `do_mycdev': f_acm.c:(.text.do_mycdev+0x38): undefined reference to `fsl_udc_irq' drivers/built-in.o: In function `serial_putc': f_acm.c:(.text.serial_putc+0x60): undefined reference to `fsl_udc_irq' So then I tried changing barebox/drivers/usb/gadget/Makefile: ---obj-$(CONFIG_USB_GADGET_SERIAL) += u_serial.o serial.o f_serial.o f_acm.o +++obj-y(CONFIG_USB_GADGET_SERIAL) += u_serial.o serial.o f_serial.o f_acm.o and now it compiles cleanly. Unfortunately, I don't have any hardware to test the binary on =/ I'm using codesourcery 2009q3 compiler, barebox 'next' git branch. My goal with this exercise is to see if I can bring a fresh custom AM3517-board up to kernel-life using nothing but a USB-cable. //Henrik _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
