Cannot access some pins at board level, especially WIFI SDIO data line in board ICT test. That cause lower test coverage.
but at board level, since we have access on many other pins, is there any possibilities of some indirect tests for this chip via those pins?
Like that GPIO1/GPIO2 is for debug which we have access, then what kind of possible checking through this 2 pins?
Not sure if other possible method for indirect test, and what kind of checking?
