Did you get a proper device initialization on BMA421 (i.e. INTERNAL_STATUS.message=0b1, which is Register 2A, bits 4..0)?
You are welcome to check for yourself.
The BMA421 driver in https://github.com/sethitow/mbed-pinetime is, line-for-line, identical to the oldest version of the BMA423 driver at https://github.com/BoschSensortec/BMA423-Sensor-API (although I have seen other BMA421 drivers floating around that are identical to BMA423-Sensor-API C code but come with a different firmware).
