TS-7300 MANUAL

 

GETTING STARTED & SOFTWARE 

The new SD image will look at the state of jumper 6. If jumper 6 is on, the full Debian 
bootup will be bypassed and the system will instead drop straight to a shell prompt. 1.69 
seconds after power-on the serial console prompt is active and 2.41 seconds after power-
on the video console is displayed. Video takes a bit longer to start up due to the fact that 
the  FPGA must  be initialized,  a splash  screen  is displayed,   and USB  keyboard  kernel 
modules must be loaded. To initiate a full Debian startup, simply type "exit" at either the 
shell prompt on the serial port or the shell prompt on the VGA monitor (using keyboard).

The time it takes for bootup is also displayed right before the SH prompt is printed. On 
new Rev C CPLD TS-7300's, the CPLD has a 32-bit counter that starts at 0 at poweron 
and   is   used   to   measure   the   bootup   time   extremely   accurately.   On   other   boards,   the 
EP9302  983Khz debug4  timer is used since it  starts  out  as 0  also, but  is slightly  less 
accurate than the 32-bit 14.7Mhz counter implemented in the new CPLD rev.

If you want something other than a shell prompt running as soon as possible on bootup, it 
is possible by editing the /linuxrc2 shell script on the initrd. When you do the fast boot, you 
are actually booting to an initrd with the Debian parts of filesystem mounted read-only. 
After modifying the /linuxrc2 shell script on the initrd, run the "save" command to save the 
initrd back to the SD card, otherwise your changes won't "stick".

The TS-7300 bootup firmware was designed to be much faster than a x86 PC/SBC BIOS. 
So even better bootup times can be achieved with an RTOS, such as eCos, instead of 
Linux. Of that 1.69s bootup time, about 1.4 represents Linux bootstrap, while about 0.3 of 
it is the hardware initialization.

Installation

If  you board doesn't  have the Fast Bootup firmware installed  from  factory,  proceed as 
follow in order to have your TS-7300 upgraded.

The new SD Card image that enables the fast bootup option is available on our FTP site. 
Visit our website, TS-7300 page, for further information.

It requires at least a 256MB SD Card. To install it, follow the instructions below: 

1. Extract the new SD Card image file, for example:

$ bunzip2 fastboot-7300-sdcard-7-6-2006.dd.bz2

 

2. Using   an   SD   Card   reader   and   the   "dd"   utility,   copy   the   image   to   the   disc   device

of the 256MB SD Card:

$ dd if=fastboot-7300-sdcard-7-6-2006.dd of=/dev/sda

Or, using the second SD Card slot of your TS-7300:

$ dd if=fastboot-7300-sdcard-7-6-2006.dd of=/dev/sdcard1/disc0/disc

!

Warning

This   will   completely   overwrite   the   contents   of   your   SD   Card,   so   make
sure you do the appropriate backups before updating.

3. To   use   the   image   on   a   larger   card   (512MB,   for   example),   just   "dd"   to   the   larger

card,   use   fdisk   to   increase   the   size   of   part3   to   the   remaining   space   (taking   care
to   keep   the   same   start   sector),   and   then   use   the   "ext2resize"   command   on   that
partition:

$ fdisk /dev/sdcard1/disc0/disc

$ ext2resize /dev/sdcard1/disc0/part3

 

4. To   update   to   the   new   TS-SDBOOT,   download   and   run   (as   root)   the

TS-SDBOOT   update   utility   binary   executable   on   your   TS-7300   board.   This   utility   is 
found at our webiste.
