Dear all,

 

We want to set eFuse after Linux start.

We found /sys/fsl_otp in Linux on MX6UL.

 

Can we use this file to set the following register?

Would you tell me the setting procedure if it is possible?

 

Bank 0, Word 0 (OCOTP_LOCK) ⇒ HW_OCOTP_LOCK

Bank 0, Word 6 (OCOTP_CFG5) ⇒ HW_OCOTP_DFG5

Bank 4, Word 0 (OCOTP_SJC_RESP0) ⇒ HW_OCOTP_SJC_RESP0

Bank 4, Word 1 (OCOTP_SJC_RESP1) ⇒ HW_OCOTP_SJC_RESP1

 

Best Regards,

Yuuki
