System set up
- tftp server
- konsole/ssherminator - allows you to open as many terminals in one window as you need
- During this procedure you're gonna need at least three
- Media:Libftd2xx0.4.13.tar.gz
- Media:Openocd 1.0.1383 i386.tar.gz
- Media:Voipac-pxa27x xloader.tar.gz
- Media:Voipac-pxa27x-u-boot nostart.tar
- Media:Voipac-pxa27x u-boot original.tar
Linux kernel
You need to enable usbfs in your kernel.
Enable CONFIG_USB_DEVICEFS option in kernel options
how-to-customize-your-ubuntu-kernel
Install OpenOCD
- Copy libftd2xx.so to your /usr/lib folder
- Create symlinks for the libftd2xx by using the following commands:
- cd /usr/lib
- ln -s libftd2xx.so.0.4.13 libftd2xx.so.0.4
- ln -s libftd2xx.so.0.4.13 libftd2xx.so.0
- ln -s libftd2xx.so.0.4.13 libftd2xx.so
- tar xzfv openocd_1.0.1383_i386.tar.gz
- dpkg -i openocd_1.0.1383_i386.deb
- When trying to install this on a 64bit system you need to --force-architecture or you'll get an error.
Using OpenOCD
- Power up target board and connect JTAG
- Start the first terminal and write
- openocd -f vpac270.cfg
- Error: unable to open ftdi device: 18
- OpenOCD needs usbfs
- mount -t usbfs none /proc/bus/usb
- Error: unable to open ftdi device: 2
- You need root privileges
- log in as root or
- sudo openocd -f vpac270.cfg
- Error: unable to open ftdi device: 18
- openocd -f vpac270.cfg
- Start second terminal, use telnet to connect to OpenOCD daemon.
- telnet localhost 4444
- reset halt
- load_image /tftpboot/u-boot_noboot.bin 0x5c010000
- resume 0x5c010000
- Start third terminal
- minicom
- Use settings 38400 8N1
- set ipaddr 10.0.0.22;set serverip 10.0.0.16;erase 1:0-2;tftp x-load.bin;cp.b a1000000 0 400;tftp u-boot.bin;cp.b a1000000 800 $(filesize);reset
- minicom
