BQ27510-G3 DFI write

Intellectual 460 points

Hi,

We are implementing DFI write algorithm based on SLUA449F( "Going to Production with the bq275xx") document for BQ27510-G3 chip.

So we have following query.

Based on the Figure 8(in the page number 9 of SLUA449A:- Section:Instruction Flash First Two Row Record and Erase Flow)After flash erase in DFI write alogorithm,We send DFI read command 0x66 with data 0x00(Before start of writing DFI image).Our issue is that this command return fails in some attempts of DFI write. What is the reason for this?

Regards,

Anoop
