I am using Jetson AGX Orin 32GB Developer Kit at version 5.1.1
I have a battery with smbus connection. I want to establish SMBus connection from i2c. There is SDA, SCL, Negative and Positive. So I soldered a jack for negative and positive then two jumper for SDA anc SCL. Then I checked them with ammeter.
Battery can power the Orin but when I connected SDA (3rd pin) and SCL(5th pin). I can get no result for
i2cdetect -y -r 0…8
I tried to use
sudo su sudo sh -c 'for i in 2 3 4 5 6 7 8 9; do echo 1 > /sys/kernel/debug/bpmp/debug/clk/i2c$i/mrq_rate_locked; done' sudo sh -c 'for i in 2 3 4 5 6 7 8 9; do echo 100000 > /sys/kernel/debug/bpmp/debug/clk/i2c$i/rate; done'
(I also tried 10khz, 1khz)
Then tried i2cdetect again but still there is no result. Am I doing something wrong? Can I get SMBus connection for battery?
