Tool/software:
Hi Team,
We are using BQ25792 in our current Project. We have tried to set the Battery Termination current control register to 200mA from 1A(which we had earlier set using PD customization tool) of the Battery charger IC using I2C command. But Unfortunately, we could not get the expected result and the Power was shutdown. As a result , the processor and the PMIC got damaged. We have a doubt with the command we have provided on the uboot.
The command we gave: I2c mw 0x6B 0x09.2 0x05 1
Could you please suggest what might have caused with this command? Is there any possibility of writing to the 0xA register with the above command i.e changing the system voltage to be greater than 4.2V?
The log is attached below for your reference.
Best Regards,
Monisha M
