Hi Bosch Team, I am facing an issue that ralates to accelerate FIFO. It seems like the data is correct enough all the time, but when I try to halt reading FIFO buffer for a while then the issue happens.     25036 X135 Y-154 Z11205 25041 X136 Y-158 Z11206 25045 X135 Y-164 Z11204 25050 X135 Y-165 Z11203 25054 X131 Y-169 Z11201 25059 X129 Y-169 Z11197 25063 X128 Y-166 Z11195 25068 X129 Y-161 Z11194 25072 X131 Y-157 Z11192 25077 X133 Y-150 Z11193 25081 X134 Y-151 Z11193 25086 X133 Y-148 Z11194 25090 X135 Y-159 Z11196 25095 X137 Y-158 Z11200 25099 X137 Y-165 Z11203 25103 X138 Y0 Z0 25108 X138 Y0 Z0 25113 X126 Y-161 Z11195 25118 X125 Y-157 Z11195 25122 X123 Y-158 Z11192 25127 X133 Y-160 Z11202 25131 X131 Y-148 Z11197     I mean "correct enough" because there is sometimes the data output is 0 on Y and Z and it's totally incorrect. After halting the reading data from FIFO buffer, then read it back, the data is not correct anymore after hundred miliseconds     32065 X131 Y-156 Z11199 32071 X134 Y-159 Z11202 32075 X131 Y-165 Z11200 32080 X133 Y-164 Z11202 32084 X133 Y-163 Z11198 32089 X134 Y-160 Z11199 32093 X135 Y-159 Z11195 32098 X135 Y-157 Z11193 32102 X136 Y-156 Z11190 32107 X134 Y-153 Z11190 32111 X134 Y-151 Z11192 32115 X132 Y-147 Z11197 32120 X133 Y-145 Z11201 32124 X135 Y-143 Z11204 32129 X134 Y-145 Z11204 32133 X137 Y-149 Z11207 32138 X135 Y-154 Z11205 32142 X136 Y-158 Z11206 32147 X135 Y-164 Z11204 32151 X135 Y-165 Z11203 32156 X131 Y-169 Z11201 32160 X129 Y-169 Z11197 32165 X128 Y-166 Z11195 32169 X129 Y-161 Z11194 32174 X131 Y-157 Z11192 32178 X133 Y-150 Z11193 32183 X134 Y-151 Z11193 32187 X133 Y-148 Z11194 32192 X135 Y-159 Z11196 32196 X137 Y-158 Z11200 32200 X137 Y-165 Z11203 32205 X138 Y0 Z0 32210 X138 Y0 Z0 32220 X123 Y-158 Z11192 32225 X129 Y-156 Z11196 32230 X129 Y-159 Z11197 32234 X131 Y-160 Z11201 32239 X132 Y-162 Z11204 32243 X131 Y-161 Z11207 32248 X130 Y-161 Z11207 32252 X129 Y-160 Z11209 32257 X126 Y-159 Z11205 32261 X126 Y-154 Z11201 32266 X128 Y-155 Z11195 32270 X131 Y-154 Z11192 32275 X133 Y-156 Z11190 32279 X139 Y-154 Z11192 32284 X137 Y-154 Z11191 32288 X141 Y-150 Z11196 32293 X138 Y-152 Z11193 32297 X140 Y-154 Z11196 32302 X136 Y-158 Z11195 32306 X138 Y-159 Z11196 32310 X137 Y-161 Z11195 32315 X142 Y-159 Z11199 32319 X142 Y-158 Z11198 32324 X144 Y-154 Z11201 32328 X141 Y-153 Z11196 32333 X140 Y-149 Z11196 32337 X134 Y-148 Z11189 32342 X134 Y-147 Z11190 32346 X131 Y-146 Z11189 32351 X132 Y-147 Z11193 32355 X134 Y-149 Z11193 32360 X135 Y-152 Z11196 32364 X139 Y-155 Z11195 32369 X138 Y-155 Z11197 32373 X-120 Y11200 Z-30332 32379 X-120 Y11200 Z-30332 32385 X136 Y-157 Z11197 32389 X134 Y-155 Z11199 32394 X131 Y-155 Z11196 32398 X-31611 Y131 Z-160 32404 X-31611 Y131 Z-160 32409 X133 Y-157 Z11197 32414 X134 Y-155 Z11199 32419 X131 Y-155 Z11196 32423 X-31611 Y131 Z-160 32428 X-31611 Y131 Z-160 32433 X133 Y-157 Z11197 32438 X134 Y-155 Z11199 32443 X131 Y-155 Z11196 32447 X-31611 Y131 Z-160 32452 X-31611 Y131 Z-160 32458 X133 Y-153 Z11196 32463 X133 Y-155 Z11199 32467 X131 Y-155 Z11196 32471 X-31611 Y131 Z-160 32476 X-31611 Y131 Z-160 32482 X133 Y-153 Z11196 32487 X133 Y-155 Z11199 32491 X131 Y-155 Z11196 32496 X-31611 Y131 Z-160 32500 X-31611 Y131 Z-160 32506 X133 Y-153 Z11196 32511 X133 Y-155 Z11199 32515 X131 Y-155 Z11196 32520 X-31611 Y131 Z-160 32525 X-31611 Y131 Z-160 32530 X133 Y-153 Z11192 32535 X134 Y-155 Z11199 32539 X131 Y-155 Z11196 32544 X-31611 Y131 Z-160 32549 X-31611 Y131 Z-160 32554 X134 Y-153 Z11192 32559 X134 Y-155 Z11199 32564 X131 Y-155 Z11196 32568 X-31611 Y131 Z-160 32573 X-31611 Y131 Z-160 32578 X134 Y-153 Z11192 32583 X134 Y-155 Z11199 32588 X131 Y-155 Z11196 32592 X-31611 Y131 Z-160 32597 X-31611 Y131 Z-160 32603 X134 Y-150 Z11192 32607 X133 Y-155 Z11199 32612 X131 Y-155 Z11196 32616 X-31611 Y131 Z-160 32621 X-31611 Y131 Z-160 32627 X133 Y-150 Z11192 32632 X133 Y-155 Z11199 32636 X131 Y-155 Z11196 32641 X-31611 Y131 Z-160 32645 X-31611 Y131 Z-160     I can solve this issue by soft reset, load config file, set measurement config, etc...as the same at the first time I initialize the sensor. But I do not prefer this approach and tried to reset FIFO by issue the set watermark command but it did not work. The data is raw, mean LSB. Sensor is configured to water mark iterrupt = 200, ODR=12.5Hz, range=3g, extract 1 frame per time. Any suggestion to find the root cause is appreciated. Thanks and Regards ... View more
