The code went to a lot of trouble to issue either a start+stop condition or a repeated start condition only to follow it with a stop condition and a read(2) call that issues a new start condition. So, fix the read in I2C_MODE_REPEATED_START mode by using I2CREAD ioctl within the running transaction. This obviously requires that the slave address has the read bit set which was not required before. Another problem was with width parameter of zero and I2C_MODE_REPEATED_START mode. In that case we issued a repeated start without any preceding start. While here, remove the redundant (unused) argument to I2CSTOP throughout the program. Also, clarify the meaning of -w option, especially "-w 0", in the manual page. Reviewed by: no one Differential Revision: https://reviews.freebsd.org/D12331 |
