I am using Analog lauchPad which connect to DS90UH940 and DS90UH940 connect to DS90UH925.

On Analog Analog lauchPad we saw "Unknown FPD-Link III Serializer" error, error message shown as below

in the partner information, the revision and I2C address looks correct.

Also if Analog lauchPad is connected to DS90UH925, it can read DS90UH940 via DS90UH925.

Any idea how to solve the connection issue launchPad to control DS90UH925 via DS90UH940 ?

Hello PYTsai,

I have tested this EVMs combination and got exactly the same behaviour. It looks like it is an internal bug in ALP not recognizing the 925 remote board.

I will file an internal thread to have this corrected in newer ALP versions.
