BQ40Z50-R2: bq40z50R3_v3_09

Tool/software:

Please help confirm whether the following command to read 0x70 through I2C-Tools under the Android system is correct?

1. Write 0x0070 to the ManufacturerAccess() register (0x00).
i2cset -fy 1 0x0b 0x00 0x70 0x00 i

2. Use I2C block read (0x23) to read 32 bytes of data.
i2cget -fy 1 0x0b 0x23 i
Or use i2cdump to read 32 bytes of data from register 0x23
i2cdump -fy 1 0x0b 0x23b

No problem reading SOH=0x64

But can't read 0x70 in the same way

    Hello,

    Has this been tried using the 0x44 ManufacturerBlockAccess instead of the 0x00 ManufacturerAccess? If so, is the result the same?

    Is it possible to share a logic analyzer capture of the functioning 0x64 read and the 0x70 read?

    Regards,

    Anthony
