WL1805MOD: Testability for TI WIFI module WL18xxMOD at board level

Part Number: WL1805MOD

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?


  • Hi,

    it will not be possible at ICT if you do not have assess to these pins. The best way to test would be with the host and to establish communication with say an AP. In this way you are sending data over the SDIO buss to validate it.

    Thanks,
