Part Number: BQ27421-G1
Other Parts Discussed in Thread: BQSTUDIO

HI,

Now my customer has evaluated bq27421-G1A and they found that the sample which has ver. 1.09 firmware. I checked the EVM I have then it has ver. 1.08, so it seems the firmware has been updated recently. So can you please give your comment for following question?

  1. Please let me know the difference between 1.08 and 1.09
  2. My customer comment that the project file created from ver 1.08 can't be opened at ver 1.09 sample. So can project file created from ver 1.08 not use at ver 1.09 sample?
  3. Can we know the firmware version from date code or LTC#?

[ver 1.08 FW checked at bqStudio]

Best Regards,

Satoshi / Japan Disty

    Hi,

    I checked the thread you picked and can understand the difference between 1.08 and 1.09.
    But I have not known yet if the project file created from ver 1.08 can't be opened at ver 1.09 sample. Now I don't have the ver 1.90 sample so I can't check it on my bench.

    Best Regards,
    Satoshi

    These two versions (1.08 and 1.09) have compatible data memory format so the easiest way to fix this is to change the compare line in the flash stream file:

    ;--------------------------------------------------------
    ;Verify Existing Firmware Version
    ;--------------------------------------------------------
    W: AA 00 01 00
    C: AA 00 21 04
    W: AA 00 02 00
    C: AA 00 08 01  ; change this to C: AA 00 09 01
