Max code size of RT1050 HAB Encrypted

[kensu]

Hi

If I use RT1050 without SDRAM,

What is the max code size of "HAB Encrypted" mode?

In my understanding, the image must run on internal internal RAM or SDRAM for HAB Encrypted mode.

I read the "User Manual - MCUXpresso Secure Provisioning Tools".

For image running in internal RAM, it need move SRAM_ITC to first position.

My questions are:

1. Can "image running in internal RAM" only use the SRAM_ITC?

2. In this example, the max code side is 116K ?

3. Why shift 0x3000?

Hi,

Thank you for your interest in NXP Semiconductor products and

for the opportunity to serve you.

1) Can "image running in internal RAM" only use the SRAM_ITC?

-- No.

2) In this example, the max code side is 116K?

-- Yes.

3) Why shift 0x3000?

-- The 0x3000 is the offset of the application code in the SRAM_ITC after non-XIP boot successfully. This offset is not strict to 0x3000, it depends on the developer, usually, the offset is set to 0x2000.

Hope this is clear.

Have a great day,

TIC
