Hi,
We are considering using an -E version of TI L138 device. If our current code and data in binary format is already 2M bytes, would the encrypted image grow larger in size? We ask this because if the encrypted image is too large then the current flash might not hold it.
Or can we selectively to encrypt only certain sections of the binary content? A large portion of the 2M size is images rather than algorithm, so if encryption comes at the price of increased size then we prefer only to encrypt the core algorithms.
Could anyone help?
