TS 7260 board – a look! 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 4

Connecting the board to computer Linux installed by default on onboard flash. The serial port is set to 115200 baud, 8 N 1, with no flow control In Linux- the minicom program is configured using the ”-s” parameter (minicom -s) In Windows, Putty or Hyper. Terminal can be used 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 6

Connecting an USB thumb drive 2 USB 2. 0 ports available USB flash drive has to be formatted as either ext 2 or vfat TS-Linux comes with USB drivers After booting at command prompt do “load. USBModules. sh” “mount /dev/scsi/host 0/bus 0/target 0/lun 0/part 1 /mnt/” 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 8

Connecting an USB thumb drive “Load. USBModules. sh” script loads the following modules: ◦ usbcore ◦ pcipool ◦ usb-ohci-ep 93 xx ◦ scsi_mod ◦ sd_mod ◦ usb-storage 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 9

Run “load. USBModule. sh” 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 10

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/sdcard 0” is used to mount into the file system. “cp /dev/sdcard 0/disc 0/part 1 /dev/sdcard 0/disc 0/part 3” “mount -t ext 2 /dev/sdcard 0/disc 0/part 3 /mnt” 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 12

Check the memory ! We could see all three disks and the percentage of memory usage Inference : need more memory 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 13

Check the memory! 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 14

Challenges? (as of now) 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 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 15

The progress… (as on Feb 21, 2008) Found that one of the two boards was not working Understanding the USB communication layers & protocols Understood the boot sequence and boot modes of the TS 7260 Learnt - How to write customized “Load. USB. sh” script? 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 16

What next? Install Debian linux image in flash Install gcc, g++ compliers Install cross compiler & Interface the kit Software development for USB access 2/21/2008 Connecting TS 7260 by G Alagu Ganesh 17
