Hi, I'm trying to verify some code for a STM405F board but when I try to verify it I get this error message. Haven't been able to figure out the problem as the error message is very long and confusing to me. I have verified the test code that came with the sensor and code for writing to the built in sd card. But haven't been able to verify this file which is just snippets of code from both of the examples. If anyone could help me decipher this error message and what can be done to fix it that would be amazing! Thanks!
