Other Parts Discussed in Thread: BQ27541

I would like to convert a DFI file to ascii and I understand that Flashstream does it. Where can I get it? We are trying to write our own programmer for reasons including Windows 7 64bit compatibility.

Thank you.

Marius,

Look at this chain

http://e2e.ti.com/support/power_management/battery_management/f/180/p/108739/415077.aspx#415077

There is an app note reference there : 2021.slua380-Ap Book BQ20z80.pdf - which has a function to write dfi into a device.

I have to program a bq27541.

Document "Going to Production with the bq2750x" (http://focus.ti.com/lit/an/slua449d/slua449d.pdf) has a different method than the one described in the discussion you referred to. This method involves CRC check on every write, while the one referenced above does not have CRC check

So I have two questions:

1) what is the correct method for programming the DFI file for the bq 27541?

2) for the bq27541 flash: how many rows and how long are they for programming the DFI? I don't want to spill over into firmware section of the flash, but I want to make sure that I read all the DFI.

Thank you.
