Problems while running SmartWatch sample for RT595 EVB

[sprhawk]

I'm testing SmartWatch sample under ZephyrRTOS for RT595 EVB.

I encountered serveral problems:

1. the system crashed (z_arm_usage_fault) during startup inside board.c, while calling OTP_FUSE_READ_API. It can continue after I commented all callings to OTP_FUSE_READ_API.

2. After system started up after I fixed problem 1, it didn't show graphics on the LCD screen, and the log showed scrambled code after output of SmartWatch Demo `

About OTP_FUSE_READ_API, it crashed at the highlighted instruction

I didn't see somewhere the r10 is set to some value

Hi @sprhawk 

My apologies for the delayed response, I just want to continue with the follow up for this. 

The Smartwatch demo release v2.2 was recently published. Are you still  getting the issues with this update?
