FUSE programming in imx7 ULP

Hi all,

I'd like to know the way to program eFUSE in i.MX7ULP.

I've checked a following but can't understand how to do it.

https://www.nxp.com/docs/en/application-note/AN4581.pdf

I guess there are several way to program eFUSE in i.MX7ULP such as using uuu, u-boot.

Could someone share sufficient documentation or example script ?

Hi ko-hey,

Please refer to How to Program Fuses documents that give examples on various ways to program fuses. You can use that as a sample for i.MX7ULP as well. Also, attached the Fusemap sheet that can help make things clear about OTP Fuses.

Regards,
