BQ34Z100-G1: Device not response after programmed user-defined srec file

Part Number: BQ34Z100-G1

Dear all,

I am using a custom board with a BQ34Z100-G1 on it. I programmed it with a srec file exported from other BQ34Z100-G1 and lost communication after that. Here are what I did.

  • Exported Golden Image files from one BQ34Z100-G1 (worked well) using Battery Management Studio 1.3.54.
  • Programmed a used BQ34Z100-G1 (worked well before) with exported Golden Image file.
  • After a successful operation, I lost communication with the chip
  • I tried to read registers of the chip. No response. I also tried to reprogram the device, still no response. Clicking Execute FW doesn't help.

The srec file is attached. Any suggestion is helpful.

Best,

SL61
