hi kindly advise BF527
1) how many end points does the OTG USB support?
2) Does the OTP memory support incremental programming? E.g. use part of the memory in at first, later on use the rest.
3) Does VDK have any support on flash file system? We want to utilize the NAND Flash interface. it will be easy to handle with a proper file system like JFFS/2? any other open source file system for BF527
