I would say re-enable the cache size.
I've moved on to the 20270 Kitchen w/ a 5MB PagePool and did not add all of the FATFS entries that I OP'd. Just the CacheSize(8096),DataCacheSize(204
,EnableCacheWar m(1), and EnableDataCacheWarm(1).
It is interesting to see that the builder(s) have added paging for a few of the StoreManager sections. I thought it would slow my Titan down but it seems to help.
Anyway, cheers to happy hacking.
