I2c commands in uboot

PROCESSOR-SDK-J721S2: U-BOOT i2c mw command for 16-bit I2C registers

Tool/software:

Hi All,

as far as I understand, the U-BOOT "i2c mw" command does not support write operations to 16-bit wide I2C registers.

Is this understanding correct?

Does s.o. know a trick how to write to 16-bit I2C registers from the U-BOOT prompt?

BR
Stefan
