@linguini1 Hello: > I observed this issue while writing a self-test function for the LSM6DSO32 IMU. When the selftest fails everything is fine, but when it passes the function hangs forever. I was able to confirm this by adding a log statement at the exit point and changing the return code to -EACCESS before the function returns. The log statement gets executed and the function does not hang. It does hang if I remove the error code change code and allow the function to return 0. The process of the selftest is quite straightforward: `orb_ioctl -> ioctl -> sensor_ioctl -> selftest.` Have you enabled SENSORS_RPMSG for multicore control? If not, when your upper layer calls orb_ioctl, is there a possibility that the file descriptor (fd) passed in is incorrect? > On a side note, orb_ioctl(fd, SNIOC_RESET, 0) returning -1 regardless of the error returned by the lowerhalf function is not documented anywhere I could find. I feel it should return a positive error code indicating the error that occurred, like ioctl does. "orb_ioctl" is actually equivalent to "ioctl" in that it requires using errno to determine specific error codes. However, we have internally modified it to directly return errno. I will push this pull request (PR) shortly. -- This is an automated message from the Apache Git Service.
