.bqfs programming, set full access unseal key in bq27510-g2

Hi All,

I had tried to program the FG using .bqfs. The unit is sen into ROM mode and then followed by the commands in the bqfs. We are using C# for the programming and the USB to I2C communication using a separate kit. 

We are trying to Ensure Device is not sealed from a firmware perspective. These are the steps:

1. Read ControlStatus
1. Write 0x00 in register 0x00 and 0x01
2. Read back register 0x01
1. If bit 5 is set, send Unseal key
2. If bit 6 is set, send Full Access Unseal key
3. If both keys are required, send Unseal key first then Full Access Unseal key

How will we be able to send Unseal Key and Full Access Key? is there a guide in doing this? please note we are not using bqEVSW and the EV2300 as we are to developing a programming software which could program multiple ICs instead of running multiple software.

Any help is greatly appreciated.

Thanks,

Kat
