SDRAM boot from External Flash, Using SEC tool in the mode Encrypted(HAB)Authenticated

Seongyon_Jeong — Wed, 09 Jul 2025 08:00:11 GMT

After Watching the guide video from https://www.nxp.com/design/design-center/training/TIP-MCUXPRESSO-SECURE-PROVISIONING-TOOL

In the last Scene, I Can see below table.

and, I want SDRAM executing written to External Nor Flash.

so, Link application RAM, SKIP_SYSCLK_INIT=1, Remove Flash section and modify BOARD_SDRAM section.

But I cannot Build image , because of [from] [xxxxxxx]
this toolbar position always appear RED.
only if SDCARD and NAND, It is Green.

How Can I select this option to FLexSPI NOR - simplified or complete FCB ??

Encrypted(HAB) authenticated method is only accepted on SDCARD or NAND ??

Hi,

if there is something red, the error message is displayed in the tooltip. The error message should explain, where is the problem.

In the tool documentation, here is described how to build the image to boot from SDRAM: Processor-specific workflows — MCUXpresso Secure Provisioning Tool 25.03 25.03 documentation

I Checked the sequence from Processor-specific workflows — MCUXpresso Secure Provisioning Tool 25.03 25.03 documentation

but Still Cannot build Image. and [ from FlexSPI NOR - simplified ] still looks RED
and then When I move mouse pointer at this toolbar,

Error: MIMXRT1020 limitation : FlexSPI NOR is not supported with Encrypted(HAB) authenticated.

==> Litterally,.... ON RT1020, Is it Impossible mode ?

then..

Does that message mean that SDRAM booting from external FlexSPI NOR flash is impossible on the RT1020?

Or is it simply because Encryption (HAB authenticated boot) is not supported on this device?

Hi,

Yes, message "Error: MIMXRT1020 limitation: FlexSPI NOR is not supported with Encrypted(HAB) authenticated." means that FlexSPI NOR is not supported on RT102x.

Same limitation is on RT1015
