number mtd partitions on 16 limits?

[hermes33 at freenet.de]

Dear all,

I need more than 16 mtd partitions on a omap1610 (arm) with kernel 2.4.20. 
I create 16 partitions. All ok, 'cat /proc/mtd' show mtd0 to mtd15. 
I create 17 partitions. 'cat /proc/mtd' show only mtd0 to mtd15. 
It seems to give a limit with 16 partitions. 
Where can I change that? can someone help me?

Best regards

Robert
