UPDATE JOIN multiple tables

Hello,

I am trying to update [SeedTracker].[dbo].[DBLogNonResInt].Cassava (bit datatype) from a bit value from another table [SeedTracker].[dbo].[Location].Cassava joined by DBLogNonResint.Location = Location.Description.  If the value in Location.Cassava is True then update the DBLogNonResInt.Cassava to True otherwise update to FALSE.

My latest failed attempt:

UPDATE
[SeedTracker].[dbo].[DBLogNonResInt]
SET
Cassava = 0.0160
FROM
[SeedTracker].[dbo].[DBLogNonResInt] nr
INNER JOIN
[SeedTracker].[dbo].[Location] l
ON
nr.Location = l.[Description]
WHERE
l.Cassava = 1

sorry, forgot the "false" part. try this:

UPDATE [SeedTracker].[dbo].[DBLogNonResInt]
SET [SeedTracker].[dbo].[DBLogNonResInt].Cassava=
        (
            CASE
                WHEN
                    (t2.Cassava=True)
                THEN
                    t2.Cassave
                ELSE
                    False
            END
        )
FROM [SeedTracker].[dbo].[Location] as t2
