Dear All,

 

The "ADSP-BF52x Blackfin Processor Hardware Reference" rev 1.0 (pag 16-34 and 16-36), reports that L1 memory from FF90 0000 to FF90 1900 is reserved for SESR scratch buffer.

 

Lockbox source code example reports that reserved space must be 0x1F00 bytes from FF90 0030 (SCRATCH_BUFFER_SIZE in secure_function.c).

 

What's the right value ?

 

Thanks.
