  1. The same, I use 2K in both SDA and SCK for PL0/PL1 and it does't work.
  2. I test in 3 boards... I put a 1KOhm pullup resistor and the port keeps searching and nothing is detected.
  3. I attach an accelerometer in i2c address "0x1D" using PA18/19 the answer is OK. But using PL0/1 the i2c keep searching and nothing is obtained
  4. it says "okay" Others i2c have the same sintaxis:
  5. Hello, I have a OrangePi Zero+2 board and I am using i2c ports for connect several devices. Some i2c works OK. But I requiere r-i2c port. But the port does not work I have spend several days trying to make it works. Please, Can somebody help me?. This is turning into a headache. Thanks in advance.
  6. Thanks martinayotte. I try to see i2c-1 but nothing is shown even when I change connections between i2c ports (0<>1). May be it's a problem related to pinmux?.

  7. Hello, I have spend a lot of time trying to make it work I2C PL0/PL1 of orangepi zero plus 2 H5. I change sunxi-h3-h5.dtsi to status="okay" and i can not to see i2c PL0/PL1 only I can see others i2c. Can anybody help me to understand what I am doing bad?
