STM32N6 .tsv file with application

[Tuomas95]

Hello,

What is the correct layout for the .tsv file for the STM32N6 with application?

In this tutorial the FlashLayout.tsv is shown, however it only has the FSBL program in it. I cannot figure out what Id to use for the Appli (also Appli non secure), i tried 0x05 but i get error:

Error: unable to get the associate alternate setting of partition ID: 0x 5
Error: please make sure that your alternate settings have string descriptors with the right format
Error: unable to switch to partition with index: 0x05

This document describes the Id's but i don't think that any of them apply, and the document is for the MPU's anyway.

Thanks!

Hello there @Tuomas95,
I have followed the tutorial with the following .tsv setup and I got it to run successfully:

#Opt	Id	Name	Type	IP	Offset	Binary
P	0x1	fsbl-openbl	Binary	none	0x0	OpenBootloader_STM32N6570-DK-trusted.stm32
P	0x3	fsbl-extfl	Binary	none	0x0	MX66UW1G45G_STM32N6570-DK-OBL.bin
P	0x4	fsbl-app	Binary	nor0	0x0000000	GPIO_IOToggle_FSBL_Trusted.bin

 Let me know if this works for you too.

Hello @Kouthair 

That works, however what if i also have Application in addition to FSBL? I think that is should then be something like this:

 

#Opt Id Name Type IP Offset Binary
P 0x1 fsbl-openbl Binary none 0x0 OpenBootloader_STM32N6570-DK-trusted.stm32
P 0x3 fsbl-extfl Binary none 0x0 MX25UM51245G_STM32N6570-NUCLEO.stldr
P 0x4 fsbl-app Binary nor0 0x0000000 GPIO_IOToggle_FSBL_Trusted.bin
P 0x5 appli-app Binary nor0 0x0100000 GPIO_IOToggle_Appli_Trusted.bin

But i cannot find any documentation for what Id to use for the appli-app? With the above .tsv it writes the fsbl-openbl, fsbl-extfl and fsbl-app correctly, and then fails in appli-app. I have tried with various Id values, but i always get the error:

Error: unable to get the associate alternate setting of partition ID: 0x 5
Error: please make sure that your alternate settings have string descriptors with the right format
Error: unable to switch to partition with index: 0x05

 

Thanks!

I can flash the Appli in two stages like this:

• Set BOOT0 to 1
• reset MCU
• flash FSBL with CubeProgrammer:

#Opt Id Name Type IP Offset Binary
P 0x1 fsbl-openbl Binary none 0x0 OpenBootloader_STM32N6570-DK-trusted.stm32
P 0x3 fsbl-extfl Binary none 0x0 MX25UM51245G_STM32N6570-NUCLEO.stldr
P 0x4 fsbl-app Binary nor0 0x0000000 GPIO_IOToggle_FSBL_Trusted.bin

• reset MCU (without this the Id 0x4 of the next stage is rejected)
• flash Appli with CubeProgrammer:

#Opt Id Name Type IP Offset Binary
P 0x1 fsbl-openbl Binary none 0x0 OpenBootloader_STM32N6570-DK-trusted.stm32
P 0x3 fsbl-extfl Binary none 0x0 MX25UM51245G_STM32N6570-NUCLEO.stldr
P 0x4 appli-app Binary nor0 0x0100000 GPIO_IOToggle_Appli_Trusted.bin

• set BOOT0 to 0
• reset MCU -> Appli runs

This is a bit of a workaround i think, and not a proper solution
