How to Program eFuses for QSPI in the i.MX6ULL Custom Board?

[Embedded-world]

Dear Experts,

I'm new to the concept of eFuse programming & would like to understand how to approach this for a custom board based on the i.MX6ULL.

Could you please provide guidance on the following:

1. Understanding eFuse Programming:
What exactly is eFuse programming, & how does it apply to a custom board?

What are its benefits and uses, specifically in the context of the i.MX6ULL?

2. Programming eFuses for QSPI:
How can I program the eFuses on a custom i.MX6ULL board? Are there specific tools, steps, or methods I should follow?

If there are any reference materials, guides, or examples available, please share them.
This would greatly help in understanding the eFuse programming process and its application for the i.MX6ULL.

Thank you for your assistance.

Best regards,
Ravikumar

Hello,

1. The eFuses are a location to store different kinds of permanent configuration settings. This could, for example, be boot configuration, MAC address, secure boot settings, and so on.

2. Please take a look on the next guide to understand the process of read and write eFuses on your i.MX device.
