Re: [ts-7000] auto boot from sd card without the ts-752 board.

[Jonathan Leslie <>]

I got it!     I attached pin 5 on the 44 pin connector (the MODE2 pin??) to a 700 ohm resistor, and tied that to ground.   

44-Pin Header

The TS-7500 includes a .1" pin spacing external header for board to board interfacing. The TS-7500 external interfaces uses a total of 44 pins.

Pin table:

3.1 44-Pin Header

Pin#	Name	Function
1	JTAG_DOUT
2	JTAG_TMS	4.7k pull-up
3	JTAG_CLK	2.2k pull-up
4	JTAG_DIN	4.7k pull-up
5	DIO_05	DIO, XUART#0 TX, RS232 RTS on TS-752, 4.7k pull-up
6	DIO_06	DIO, XUART#0 RX, RS232 CTS on TS-752
7	DIO_07	Console TX, DB9 RS232 TXD on TS-752, 4.7k pull-up
8	DIO_08	Console RX, DB9 RS232 RXD on TS-752, 4.7k pull-up
9	DIO_09	DIO or ext_reset#

The DIO registers are described in the #Syscon section. This board has 40 logical DIO registers on the FPGA to remain consistant with the series, but not all of the pins are brought out. DIO 9 by default is an external reset which is pulled high, and when it is set to 0 the board will reboot. You can disable this functionality by clearing bit 4 of 0x76 in the #Syscon.

DIO Number	Location	Alternate Function
5	Pin 5 of the #44 Pin Header	MODE2, XUART 0 TX
6	Pin 6 of the #44 Pin Header	XUART 0 RX
7	Pin 7 of the #44 Pin Header	MODE1

I tried that:

"rm linuxrc; ln -sf /linuxrc-sdroot /linuxrc; save" 

*After that you will see this message: Saving initrd to SD card...done 

I ran the above from the busybox prompt but it didn't work.

Let the board boot.

Do an "ls -al" -- you should see a link of linuxrc -> linuxrc-fastboot

you will need to rm linuxrc, and then ln -s linuxrc-sdroot linuxrc

to make a new link for the boot type you want.

All in the manual, I believe.

There are many ways to run your script.  Perhaps put a line in /etc/rc.local to call it.

I have the TS-7500 on a hand made breadboard.  Currently to get to busybox, I have to:

1) set up a puTTY session to monitor the UART 0
2) when the busybox finishes booting, I type 'exit'
3) the debian linux boots off of the SD card.

I want on power up to boot directly from the SD card, or at least I want the busybox to automatically type in its own 'exit' on the console so it boots the debian linux everytime.   I then want the debian linux to run my startup_script.sh    starting whatever processes' I want,

can anybody give me step by step instructions?   The manual says I should be able to do this by setting MODE1 or MODE2, and I thought this was achievable by pulling these pins (5, and 7 respectively) to ground, but that does not seem to work.
