BQ34110: Can't write parameters

Part Number: BQ34110
Other Parts Discussed in Thread: BQSTUDIO, , EV2400

Hello, I encountered a problem that the register could not be written during the debugging of bq34110. Now use bqstudio tool to connect this ev2400 operation. Reading is normal, but it prompts a read of data written failed comparison when writing to the register.

Can you share a screenshot of the Registers Window of the bqStudio? Make sure you click the Refresh button first before taking a screenshot.

The flash update OK voltage is 2800mv, now it is changed to 100mv, and the register parameters can now be written normally. Is the value of the flash update ok voltage incorrect and can not be written?

Here is the description of Flash Update OK Voltage in the BQ34110 TRM.

I would suggest you not change the default value. If you do have to, you have to make sure the Vcc voltage does not fall below 2.4V during flash write operations.
