Hi guys,

I need to modify device tree of Orin Nano 8GB Devkit for custom board in Jetpack 6.0 to enable eeprom for support rohm,br24g256.

Currently i refer to:

Linux_for_Tegra/source/kernel/kernel-jammy-src/Documentation/devicetree/bindings/eeprom/at24.yaml

But this file only mentions “rohm,br24g01”, so could i modify to “rohm,br24g256” as below?

  • Modify “eeprom@57” of “i2c@3160000” with “rohm,br24g256”

i2c@3160000 {
status = “okay”;
eeprom@57 {
compatible = “atmel,24c02”, “rohm,br24g256”;
reg = <0x57>;
label = “system”;
vcc-supply = <&vdd_1v8_sys>;
address-width = <8>;
pagesize = <8>;
size = <256>;
read-only;
};
};

Thanks a lot!

Please check with the eerpom vendor about how their device tree would be like.
