which GPIOs pin is xavier i2c9 address 0x31e0000
scl<—> gpio?
sda<—> gpio?
i can’t find from datasheet.
hello zhouyuanyuan084,
since you would like to check the properties under the known i2c address,
I would suggest you an alternative way to disassembler the dtb file into txt file for quick checking.
for example,
dtc -I dtb -O dts -o temp.txt tegra194.dtb
then you should download the L4T sources from Jetson Download Center to have more details,
thanks
hello Jerry Chang ,
i2c@31e0000 {
4537 #address-cells = <0x1>;
4538 #size-cells = <0x0>;
4539 iommus = <0x2 0x20>;
4540 dma-coherent;
4541 compatible = “nvidia,tegra194-i2c”;
4542 reg = <0x0 0x31e0000 0x0 0x100>;
4543 nvidia,hw-instance-id = <0x8>;
4544 interrupts = <0x0 0x21 0x4>;
4545 status = “okay”;
4546 clock-frequency = <0x186a0>;
4547 clocks = <0x4 0x37 0x4 0x66>;
4548 clock-names = “div-clk”, “parent”;
4549 resets = <0x5 0x23>;
4550 reset-names = “i2c”;
4551 dmas = <0x1e 0x1f 0x1e 0x1f>;
4552 dma-names = “rx”, “tx”;
4553 pinctrl-names = “default”;
4554 pinctrl-0 = <0x39>;
4555 linux,phandle = <0x7f>;
4556 phandle = <0x7f>;
there is not i2c pins define.
hello zhouyuanyuan084,
could you please share more details about your use-case,
for example, what’s would you like to control with i2c9.
thanks
