what is the use of _loadDcdcTrim() in `1040_flexspi_nor.ini` file ?

[5angxr]

in this function, it  reads 0x401F4490 & 0x401F4480 registers, which are `Value of OTP Bank1 Word1 (Memory Related Info.) (MEM1) ` & `Value of OTP Bank1 Word0 (Memory Related Info.) (MEM0) `.

what do they really mean?

most importantly, do I need to invoke _loadDcdcTrim() in my project's debug .ini file?

Hi @5angxr ,

Thanks for your interest in NXP MIMXRT series!

This function is used to read the Trim value of DCDC in the register. Specific information is not officially released, you can follow the implementation of the SDK to write, the function is required to write ini file.

Best regards,
Gavin
