BQ27510-G2 in production

Other Parts Discussed in Thread: BQ27510-G2

I would like to have our BQ27510-G2 parts programmed at distribution before they are soldered down instead of programming them with our microcontroller or at the end of our production line.  Does anyone know if this is possible and are there any issues in doing it this way?

    Hi Jamie,

    Some distributors may be willing to provide this service for you.  If you already have the programming solution implemented with your own microcontroller, it would be even easier for them to take your method and implement it if they don't currently have the capability.

    If you have a way to store a text file, you could use a .dffs file generated by the non-official software "flashstream.exe". This dffs file contains info about the necessary I2C commands (read, write, check) and delays to write to dataflash. You'll need to follow the Application Report slua541 to parse these commands.

    I'm assuming that you need to program only the dataflash, because if you need to update the firmware too, you'll have to use the .bqfs file, also outputted by "flashstream.exe".

    To find this "flashstream.exe", search on dMax's files or try this link: http://e2e.ti.com/members/317599/files/flashstream026_5f00_bundle.zip.aspx

    Thanks everyone for your responses.  It looks like we may have our distributors program them for us.
