w/board and N-1 1c2 issue

Unread postby phaseshifter » Tue May 15, 2018 10:26 am

i see from the 40 pin connector that ic2-4 and i2-c8 are populated but the only response i can get when i probe these is all zero`s...

however 1c2-9 gives results so ic2-9 is working as far as i can tell
Code: Select all
root@odroid:~# sudo i2cdetect -y -r 9
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: 30 -- -- -- -- -- -- -- -- -- 3a 3b -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: 50 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

is it possible to get the weather board working on either of the populated header`s,,...????

The weather board should work (with appropriate software) as long as its powered from the 3.0V and not the 3.3V. The device tree will also need to be properly configured to expose the I2C on the GPIO header. I don't have any specifics since I have been focused on software rather than hardware.
