BQ27Z561: Flash Programming Issue

Part Number: BQ27Z561
Other Parts Discussed in Thread: BQSTUDIO, EV2400

I have a custom board with a bq27z561 chip. I'm trying to program calibration data to the flash using a microcontroller on the board but I can't suceed, I can communicate with the chip but I can't flash it.

So beause the I2C Interface of the bq27z561 is reachable from a connector I want to use bqStudio with EV2400 USB Adapter to calibrate and program the bq27z561.

My questions are:

1- Do you have any suggestion in order to program the chip from the microcontroller?

2- Is it right to buy an EV2400 and BqStudio for calibrate and programs the bq27z561? Any guide is available for this process?

Kind regards,

Matteo
