Dear sir:

I have some questions about BQ27510

1.We burned our own bqfs file and found that it always failed to write. The failure information is as follows:

Written data:

Every time I fail in the same place, it's troublesome.

2.Can you provide us with an official and up-to-date available bqfs document?

3.Is I2C not working after the failure of Flash burning BQ27510 in the main control software?

4.Write failed chips with master control. Can you take them down and burn them with a burner?

Attachment is source code

    Hello Onyx,

    Thanks for your support. I found the issue. There are two I2C devices on the I2C bus, one is bq27510, the another is bq24295.

    The I2C address of bq24295 is D6(write) and D7(read). The bq24295 will interference with bq27510 when bq27510 writes a block data contains D7. For example, we should write ...D7 FF... to bq27510, but the bq24295 will return its value on the bus, because D7 is its read address, so the value will be changed to ...D7 36...

    In brief, the main problem is caused by bq24295. We can close this thread.
