There was a problem hiding this comment. there are too many pddf directory in the sonic-buildimage, we should add the include path in the search path and build. There was a problem hiding this comment. @jostar-yang |

There was a problem hiding this comment. Can you re-check this and correct the offset if needed? There was a problem hiding this comment. as7726 support YM-2651Y PSU. So need this code. |
