Hello all,
I am currently trying to use Auvidea’s J20 (rev2) with Raspberry Camera v2.1 on Jetson TX1. After the 5 following commands, the GPIO LED is solid green:
sudo i2cset -f -y 1 0x77 3 0xfb # enable 1.8V power to the J20
sudo i2cset -f -y 6 0x20 6 0x3e # configure the outputs of the I2C port expander (low byte) - clock lines remain input, so there is no data collision
sudo i2cset -f -y 6 0x20 7 0x33 # configure the outputs of the I2C port expander (high byte)
sudo i2cset -f -y 6 0x20 2 0xfe # write ones to all GPIO outputs and turn on LED (low byte)
sudo i2cset -f -y 6 0x20 3 0xff # write ones to all GPIO outputs (high byte)
Then I am checking the I2C address mapping using the command “sudo i2cdetect -y -r 0” and getting an output as follows:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – – – – – – – – – – – – –
10: 10 – – – – – – – – – – – – – – –
20: – – – – – – – – – – – – – – – –
30: – – – – – – – – – – – – – – – –
40: – – – – – – – – – – – – UU – – –
50: – – – – – – – – – – – – – – – –
60: – – – – 64 – – – – – – – – – – –
70: – – – – – – – —
Since it says " The „36“ is the hex address 0x36 and indicates that no driver is loaded yet. If a driver would have been loaded it would show as „UU“ in location „36“ " on Preliminary of the J20, I understand that I don’t have the drivers needed to use Raspberry v2.1 CSI camera with J20. But how can I install / patch the drivers needed in order to use J20 on Jetson TX1?
