QSPI - NOR1 in TSV not detecting in STMCube programmer Tool

[Shashikanth]

I have two NOR flash in my hardware.

1. On SoM (Boot meadia detecting as NOR1 in Uboot)
2. On Carrier Card

Both are detecting in Uboot as Nor0 and Nor1 but in STMCube programmer i am not able to flash to Nor1.

Tool given NOR1 not found error. So not able to flash to NOR1 and Boot from QSPI.

If i put NOR0 in tsv file it is flashing to carrier card NOr flash. I wanted to flash to On SoM QSPI which is detecting as NOR1 which is not supported in TSV file.

To test , I have made the carrier card SPI4 disabled then On SoM QSPI is detecting as NOR0 and flashing and booting works.

Please let me know how to resolve this issue.

Attached the STMCube programmer error and TSV file as .txt

The issue is resolved.

The STM32CubeProgrammer tool does not support flashing to NOR1.

The problem i had is while flashing to NOR0 The Flash connected to SPI4 was detecting to NOR0, And Flash connected to QSPI was detecting as NOR1. So the tool was programming to the SPI4 flash and while booting the board trying to boot from QSPI NOR.

So in stm32mp131.dtsi i changed the QSPI node order and put it on the top of all SPI nodes. Now the QSPI NOR flash is detecting as NOR0 and flashing and booting works without any issue.

Thank you
