Hello! I'm trying to get flashforth going on a p18f4550. I've bought an experimenter board from Olimex: http://www.olimex.com/dev/pic-usb-4550.html I've git-cloned the latest flashforth, and installed the MPLAB tools that came with my PICKIT2 burner. I create a new project, add ff18_usb.asm, PF18_USB_REG.asm, and add the FF_USB_18F4550.lib file. Build appears to be successful: ends with build succeeded. I program the device and verify it, and it tells me the device is programmed successfully and verifies successfully. I plug the board into my Linux box (64 bit Ubuntu 11.04), and here's what I'm seeing in dmesg: [13843.230116] usb 6-3: new full speed USB device using ohci_hcd and address 17 [13843.370133] usb 6-3: device descriptor read/64, error -62 [13843.630123] usb 6-3: device descriptor read/64, error -62 [13843.890117] usb 6-3: new full speed USB device using ohci_hcd and address 18 [13844.040144] usb 6-3: device descriptor read/64, error -62 [13844.300133] usb 6-3: device descriptor read/64, error -62 [13844.560128] usb 6-3: new full speed USB device using ohci_hcd and address 19 [13844.980126] usb 6-3: device not accepting address 19, error -62 [13845.130133] usb 6-3: new full speed USB device using ohci_hcd and address 20 [13845.550143] usb 6-3: device not accepting address 20, error -62 [13845.550197] hub 6-0:1.0: unable to enumerate USB device on port 3 I'm assuming it's supposed to look like a USB serial device that I can connect minicom to port /dev/ttyUSB0 or the like. Any ideas on what I'm doing wrong? Cheers, Scott |
