This is not correct for your chip. You should have this set not less 
than the total number of ease units (blocks) on your chip.

For what I could find on the net this chip seems to have the following 
interesting geometry:

4 x 32kB
254 x 128kB
4 x 32kB

So, the total should be at least 4 + 254 + 4 = 262

Please fix this and provide the logs again...
