I'm porting uboot-imx of i.MX8QXP to add a sequence sending I2C data into IC chips mounted on our custom board.
I used a I2C API, dm_i2c_reg_write, when I make some code sending I2C data to change register bit field.
After writing I2C data, there was no change when I read the register on I2C bus.
What is cause of this problem?
Would you give me some advice?
