BMA490l initialization problem python

[LongToeBoy]

Hello. just got BMA490l accelerometer. i wanted to configure it from configuration array provided in github by bosch. array is posted in bma490l.c as a variable "const uint8_t bma490l_config_file[] = {....}"

im trying to initialize the ic with python script:

but looks like the last print statement always prints 0x00. can anybody help me?

No, the code you showed are still not correct code and don't expect to work properly.

You can refer to the function bma4_write_config_file in bma4.c in our Github for the process of download this configure string.

I copied part of the code here for your reference since you are not able to write the whole block in one burst write. 

rslt |= bma4_write_regs(BMA4_RESERVED_REG_5B_ADDR, &asic_lsb, 1, dev);

if (rslt == BMA4_OK) {
rslt |= bma4_write_regs(BMA4_RESERVED_REG_5C_ADDR, &asic_msb, 1, dev);

if (rslt == BMA4_OK)
rslt |= write_regs(BMA4_FEATURE_CONFIG_ADDR, (uint8_t *)stream_data, dev->read_write_len, dev);
}
