iMX eFuses

aravindchakrava — Sat, 23 Apr 2016 14:36:25 GMT

Hi,

I am new to iMX6 processors.

While referring to processor booting, I read about eFuses. I could understand different boot options using BOOT_MODE[1:0] resistors. But, I couldn't understand about the eFuses. In reference manual as well as in datasheet not much information is present about it.

I tried searching in web, but could not get exact information.. Can any one please give me generalized information about eFuses?

Thanks in advance.

Hello,

Please refer to Chapter 5 (Fusemap) and section 8.3.1 (Boot eFUSE Descriptions)

of the i.MX6 D/Q Reference Manual (IMX6DQRM, Rev. 3, 07/2015)

Have a great day,
Yuri

I tried to find answers on following questions, unfortunately without success in Reference Manual:

Are eFuses one time programmable?

Is their purpose to be programmed during production time (basically, does NXP ships chips with specific eFUse setup for the purpose of serial production?)?

Best and cheers!
