Tool/software:

Hi,

In the 09 reg, i write data 80 70 00 00 30 32. The 30 is the target address for patch in RAM, right?
which function should I use?

I used I2C_PB_MCU_I2CMasterSendStart(0x30, 0, 1); its return code is 02 means /* Last Byte Naked: INTR_MASTER_I2C_NACK                 */.

In E2E I saw it can be write 64byte at a time. Confuse me a lot how to do.

    I'm not sure what you are saying here? What do you mean by "function".

    I am not familiar with that function, please see the TRM for proper operation of PBMx.

    Are you talking about the PBMx flow? Please read section 5.2 in the TPS25751 TRM.

    Thanks and Regards,
