BHI160 without RAM firmware patch

[kwolfe]

Can anyone provide some reference firmware/drivers showing usage of the BHI160 device with using the default internal functionality?  The following wasn't sufficient:

if ( bhy_initialize_support() == BHY_SUCCESS )
{
LOG("IMU Successfully initialized\n");
}
else
{
LOG("IMU init errors\n");
return;
};

uint8_t chip_control = 0x01; // CPU_RUN_REQUEST
bhy_write_reg(BHY_I2C_REG_CHIP_CONTROL_ADDR, &chip_control, 1);

Update: We forgot pull-ups on the BHI ASCK & ASDA pins.  This may be the issue - TBD.

Adding the pull-ups gets us farther and allows us to use existing examples that program on patches.  However, I cannot get the BHI160 to report sensor data unpatched.

It is mandatory to upload a RAM patch to the BHI160 (after every first power-on or reset) before it can report sensor data.
