Hi Poppy,

SPRT requires the shared library shall not own static R/W data. ITS filesystem may not satisfy this requirement.

Usually, a SP, for example Protected Storage, can rely on ITS service to access data in non-volatile memory.

Subject: [TF-M] A question on tfm its filesystem

Hi,

I'd like to ask a question to see if the filesystem part of tf-m its partition can be moved to lib/sprt folder,to make this filesystem a shared library for PRoT part of tfm.

Therefore,besides its partition, other extra secure partitions can also make use of this filesystem.  

Best Regards,
Poppy Wu
