Hi Jackey

fuses are one time programmable and its state can not be reverted back.

Hi igor,

Thanks for your message.

Now, CPU Board(iWave i.MX6 Sodimm) is not working due to the changed OCOTP_CFG5 and OCOTP_CFG6.

iWave i.MX6 Sodimm is Download mode. How to aviod the download mode? 

iWave i.MX6 Sodimm Memory is using SPI NOR and eMMC.

SPI-NOR -> u-boot image

eMMC ->  Kernel Image and rootfs image

Thanks,

Jackey
