USB-UART example ported the gcc original code by Atmel gcc-port by Martin Thomas -------------------------------------------------------------------- This is a port of the demo-project AT91SAM7S-USART_USB_SAM7S which is available from at91.com for the IAR EW to the GNU-toolchain (arm-elf-gcc et. al.). Done for the gcc-port - new: Compil/srcWinARM/* (based on my "gamma"-example files, slightly modified and updated) - new: src/Makefile, src/swi_handler_user.c - modified: cdc_enumerate.c: disabled uint currentReceiveBank (shadows automatic variable) -> avoid warning - midified: cdc_enumarate.c: changed USB PID from 6124 to 6125 to avoid conflicts with the Atmel examples and SAM-BA et al (don't use this PID in production!) - new: inf_drv/*, the file atm6125_virtualserial.inf should be compatible to the inf-file atm6124.inf mentioned in the html-documentation but not available in the package from Atmel. Exception: PID is 6125 in atm6125* as indicated with the filename Installation and Test: ---------------------- **** STEP 1 - compile binaries **** C:\WinARM\examples\at91sam7s_usart_usb\AT91SAM7S-USART_USB_SAM7S\src>make all -------- begin (mode: ROM_RUN) -------- arm-elf-gcc (GCC) 4.1.1 (WinARM) Copyright (C) 2006 Free Software Foundation, Inc.

If your flash-software only supports Intel-HEX change to FORMAT=ihex and do make clean all. The makefile and the included files are prepared to use OpenOCD as flash-software (OpenOCD can handle FT2232-based and Wiggler-type JTAG-interfaces). Flashing is done with a simple make program C:\WinARM\examples\at91sam7s_usart_usb\AT91SAM7S-USART_USB_SAM7S\src>make progra m Programming with OPENOCD openocd_go_flash.cmd Info: openocd.c:82 main(): Open On-Chip Debugger (2006-09-28 20:00 CEST) Warning: arm7_9_common.c:679 arm7_9_assert_reset(): srst resets test logic, too Info: target.c:219 target_init_handler(): executing reset script 'openocd_at9 1sam7s_flash.script' Warning: arm7_9_common.c:785 arm7_9_halt(): target was already halted Warning: arm7_9_common.c:679 arm7_9_assert_reset(): srst resets test logic, too **** STEP 3 - Windows driver **** The application uses usbser.sys which is part of MS-Windows 2000 and MS Windows XP. Connect the evaluation-boards USB-connector with your PC. After the application has been uploaded to the controller's flash or the controller restarts Windows will detect a new USB-device and ask for a driver if it has not already been installed. Select browse for driver, other location, select the at6125_virtualcom.inf file include in the package. You need Administrator user-rights to install the driver (and only for installation, "everyone" can use later) **** STEP 4 - Test **** MS Windows will assign virtual COM-Port automaticly. Connect a "legacy"-COM port of your PC to the UART-connector of the eval.-board In my tests Windows assigned COM7 to the virtual COM-port and I connected COM2 to the UART-connector (J2) fo the eval.-board. To test the software I have used two instances of a terminal-software (Bray's terminal): one connected to COM7-the virtual USB (115200,8,n,1) the other to COM2 (115200,8,n,1). The result is shown in the screenshot (file test.png). That's it for now. Have fun, Martin Thomas
