Cubie2 A20 Fex : UART3

[Bino Oetomo]

Hi All

I use Cubieboard2_Debian_3.8_wheezy_3.4.107.raw for my Cubie2 (2012-09-09).

Looking at [uart_para3] in the fex (created with bin2fex after nand install)

 

[uart_para3]
uart_used = 1
uart_port = 3
uart_type = 4
uart_tx = port:PH00<4><1><default><default>
uart_rx = port:PH01<4><1><default><default>
uart_rts = port:PH02<4><1><default><default>
uart_cts = port:PH03<4><1><default><default>

I check if the pins is used by other 'function'
And found that it used by lcd1_para
 

[lcd1_para]

lcdd0 = port:PH00<2><0><default><default>
lcdd1 = port:PH01<2><0><default><default>
lcdd2 = port:PH02<2><0><default><default>

lcdd18 = port:PH18<2><0><default><default>
lcdd19 = port:PH19<2><0><default><default>
lcdd20 = port:PH20<2><0><default><default>
lcdd21 = port:PH21<2><0><default><default>
lcdd22 = port:PH22<2><0><default><default>
lcdd23 = port:PH23<2><0><default><default>
lcdclk = port:PH24<2><0><default><default>
lcdde = port:PH25<2><0><default><default>
lcdhsync = port:PH26<2><0><default><default>
lcdvsync = port:PH27<2><0><default><default>

I disabled the LCD1

But where is that PH00 on the Extention Port  ?
Is there any docs on PortName to Extention-Port-PIN mapping ?

Sincerely

It's not necessary that it's on the extension port.

I really appreciate your very fast respons

It's not necessary that it's on the extension port.

 

http://docs.cubieboard.org/cubieboard1_and_cubieboard2_gpio_pin

From that doc, there is no lcd1-D0.
Is that mean that  PH00 is not on ExtentionPort (and so there is no chance to get uart3)?
