Hey all,
I've been learning/working on the 53 and have had some issues adding in the AMG8 example.
i've gotten the sensor to work flawlessly on an STM32 & nordic 52 but am unable to get it going on zephyr.
My log when running looks like this

everything else should be disabled, i've made sure in the makefile all the proper files were added from the example amg88 folder/ overwritten in mine.
for ease sake i used the hello world example to modify.
the interrupts for the sensor and the twi are default so 60 and 90 so that shouldnt be an issue.
i've tried
-different pins,
-disabling anything thats using < 0x9000 0x1000 >
- double checking the parameters in the dts.
- checked the setup code and when it attempts to pulse the clock line it doesnt do anything (checked this on multiple sets of pins)
any help is appreciated.
