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

[Seongyon_Jeong]

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
