hello mszeta,
it’s due to you’ve add --mandatory_pinmux_file option.
the mandatory_pinmux.txt it’s an information for PinMux configuration for the bring-up process.
the mandatory (must have) configurations will be like hardcoded, such that mandatory configurations cannot be changed.
for example, this mandatory configurations used specific for IOs in PinMux configurations, such as I2C SCL/SDA pins should be in input enable mode.
so,
you may try removing --mandatory_pinmux_file options to avoid these errors.
thanks
