I'm using the source codes from https://github.com/BoschSensortec/BMA456-Sensor-API, the config file has been programmed through i2c but the value from reg BMA4_INTERNAL_STAT is still 0x0 which means the initialization isn't completed. I tried to find any clue by dumpping some error registers but haven't got any idea yet.
[00:00:00.000,000] <info> app: -config_stream_status=0x0
[00:00:00.000,000] <info> app: -BMA4_INTERNAL_ERROR[5F]=0x0, rslt
[00:00:00.000,000] <info> app: -BMA4_ERROR_ADDR=0x0, rslt
[00:00:00.000,000] <info> app: -BMA4_STATUS_ADDR=0x10, rslt
[00:00:00.000,000] <info> app: -BMA4_INIT_CTRL_ADDR=0x1, rslt
[00:00:00.000,000] <info> app: -BMA4_POWER_CONF_ADDR[7C]=0x2, rslt
It's a bit weird that same code works with the reference board(The Grove - Step Counter(BMA456)), but i don't see any hw change will cause this issue, given the i2c communication works well.
I also looked at the link https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BMA456-Init-Fails/m-p/20683#M5944 and make sure i'm following the suggestions provided.
Any advice would be much appeciated to locate this issue.
