Hi,

[quote user=""]<err> os: r3/a4: 0x40009000[/quote]

This is the base address of TWIM1 (and UARTE1/SPI*1), and it indicates that the fault is due to a permission issue.

Could you try to disable TFM logging to see if this is the root of the issue? TFM uses uart1 by default, which collides with your usage of i2c1.

CONFIG_TFM_SECURE_UART=n
CONFIG_TFM_LOG_LEVEL_SILENCE=y

Kind regards,

Håkon
