i.MX6 Fuses function

YairBA — Thu, 03 Jun 2021 07:35:22 GMT

From IMX6SDLRM Rev. 5 (05/2020) -> Table 5-8. Fusemap Descriptions:

MEM_TRIM_LOCK: Trimming fuses. Burned on the tester or by customer before the final product shipment.

What is the meaning of "Trimming fuses"?

Thanks,

Yair

Hi Yair

trimming fuses are used on factory for adjusting internal electrical characteristics

needed for programming.

Best regards

Thanks Igor,

By 'factory' you mean NXP or you mean any vendor that distributes i.MX6 based boards?

What are these 'internal electrical characteristics' ?

Thanks,

Yair
