Serial port on Scroll (ttySCA0)

[RichardP]

Hi All,

Looking at the /proc/cmdline the console is on ttySAC0 - Does anyone know where this device is? (pins on the board? USB? anyting?)

Hi Richard,

(First post for me) - working through the forum especially the pics of the teardown http://blueprinted.co.uk/clarity/ there is a pinout consisting of 4 pads labelled CON1 . It would be a large leap to think that this might be of of the serial ports referred to in /proc

If you open the terminal and go to /proc/tty/ and then cat drivers you can see that:
ttySAC /dev/tty-uart 204 64-69 serial

more information can be found doing: cat /proc/driver/ttySAC which shows that there are 6 serial ports however only the first 2 seem to be properly setup:

0: uart:uart0 mmio 0xF0532000 irq 64 tx: 48 rx: 0 RTS CTS DTR DSR CD
1: uart:uart1 mmio 0xF0532100 irq 65 tx: 0 rx: 0 CTS DSR CD

The device files are also present in /dev

Looking here: viewtopic.php?f=9&t=273&p=3109&hilit=serial#p3109 you can see that there are 6 serial ports on this SOC (which are all accounted for).

The other option is that CON1 is a USB port - as the USB OTG port is accounted for at the bottom of the machine this could be USB 1.1 Host

Both would be quite cool hacks to add to the scrollforum knowledge base.

My suggestion on how we could work out what is what is to open up a scroll tablet, first using a multimeter check out the voltages on the pins, if it was a usb port we would expect one pad to be 5v and the other ground, the other 2 pads being data- and data+. However I guess you could think that serial could be vcc, rx, tx, gnd as well.

The best way would be to connect up up those pads to a ttl serial port (well gnd and tx) and then transmit data over the serial port such as:

echo "test" >/dev/tcc-uart0

if it is a serial port you 'should' get data out the other side. In contrast attaching a usb device to CON1 and seeing if anything was detected might work - i think the serial port experiment is probably the simplest and easiest.

Now to summon the courage to crack open my scroll tablet.

Found it!

On my version of scrolltablet there are 4 pads close to the sd card slot, the one nearest the slot is ground and then the 3rd pad from the slot is tx - if you connect these to 3.3v (ttl) serial port and have the baud rate set to 115200 you'll see the machine boot:

Now to find rx...

[jamescoxon]

connecting up rx gives me full serial terminal for Scroll.

The pin out is therefore - going from the pin nearest the sd card:

1 - GND
2 - Rx
3 - Tx
4 - VCC

[RichardP]

This is indeed good news... I Will open mine and take detailed pictures. The serial allows for everyting

[jamescoxon]

Now that we have access to the serial port it opens up a load of new options:

* GPS
* GSM modem - would allow you to send sms, make calls and also some (slow) data connections.
* Gain access to root without 'rooting' your device
* Bluetooth, XBee communications
* Robotics
* Microprocessor and sensors.

[jamescoxon]

Just as an addition to the thread - this serial port seems to only be able to be properly used at these baud rates:

19200
57600
115200

For some reason 4800 and 9600 are garbled when sending and receiving data - can't seem to work out why - makes it a little harder to add GPS as most run at 4800 or 9600!

This can be set using busybox:

Code: Select all

./busybox stty -F /dev/tcc-uart0 speed 115200

It'll return the previous baud rate.
