Connecting the board to computer Insert the actual configuration picture 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Connecting the board to computer Linux installed by default on onboard flash. The serial port is set to 115200 baud, 8N1, with no flow control In Linux- the minicom program is configured using the “-s” parameter (minicom -s) In Windows, Putty or HyperTerminal can be used 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Connecting an USB thumb drive Insert the picture with USB thumb drive connected to the board 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Connecting an USB thumb drive 2 USB 2.0 ports available USB flash drive has to be formatted as either ext2 or vfat TS-Linux comes with USB drivers After booting at command prompt do “loadUSBModules.sh” “mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt/” 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Connecting an USB thumb drive “LoadUSBModules.sh” script loads the following modules: usbcore pcipool usb-ohci usb-ohci-ep93xx scsi_mod sd_mod usb-storage 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Run “loadUSBModule.sh” 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Run “LoadUSB.sh” 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Connecting a SD card A binary Linux driver module and a set of generic, OS-independent read/write routines is in ARM object (.o) file by default After the SD Card module is loaded, the device entry “/dev/sdcard0” is used to mount into the file system. “mount -t ext2 /dev/sdcard0/disc0/part3 /mnt” 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Check the memory ! We could see all three disks and the percentage of memory usage Inference : need more memory 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Check the memory! 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

Challenges? (as of Feb 14,2008) Older version of linux kernel No onboard software development support Very low memory available Technical user manual and actual configuration details not exactly matched No special debugger Solution: Development KIT 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

The progress… (as on Feb 21,2008) Understanding the USB communication layers & protocols Understanding the boot sequence and boot modes of the TS 7260 Understanding loadUSB script files Working on Debian Linux on flash drive Able to write, compile, execute C programs onboard 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

The progress… (contd..) 2/26/2008 Connecting TS 7260 by G Alagu Ganesh

What next? Install Debian linux image in flash ? Install gcc, g++ compliers ? Install cross compiler & Interface the kit Software development for USB access 2/26/2008 Connecting TS 7260 by G Alagu Ganesh
