BQ27530-G1: Fuel Gauge Stuck in ROM mode while flashing

Part Number: BQ27530-G1

Tool/software:

Hi Team,

We are using BQ27530 and STM32 MPU in our custom board. When we tried flashing the golden image in BQ27530 from MPU unfortunately MPU power is turned off, so fuel gauge got stuck in ROM mode.

When we remove and insert back power for BQ27530, for the first time alone fuel gauge I2C is getting detected. After that Fuel Gauge is not getting detected

We tried EXIT ROM mode commands as well, it is not exiting from ROM mode.

Note: In the idle case entering and exiting ROM mode is working fine. Once the flashing is hanged, Fuel Gauge is not exiting ROM mode

Please provide your suggestions for exiting the ROM mode when hanged in between flashing the golden image

Warm Regards,

Mythili B
