Forum Post: BQ27510 - After connecting battery, device comes up in ROM mode

Hello,

My system has a battery that can be disconnected and reconnected.  Currently I am doing firmware development using Code Composer Studio.  Therefore when I reset the system, I disconnect the battery, reconnect it, and then turn on power to the system.

On power up, he BQ27510 will not respond when addressed using I2C address 0xAA, but it will respond when addressed using address 0x0B, indicating that it is in ROM mode.  After the DFI programming, it will respond to address 0xAA from then on (indicating that it is in NORMAL firmware mode).

What is going on here?  Why does it not come up in FW / normal mode?

Thank you.
