How to avoid download mode?

[jackeyko]

Dear NXP Team,

Precondition is as below:

I have wrriten OCOTP_CFG5 and OCOTP_CFG6 using fuse command in U-Boot.

 1) fuse prog 0 5  0x18000030

 2) fuse prog 0 6  0x00000010

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.  

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

SPI-NOR -> u-boot image

eMMC ->  Kernel Image and rootfs image

How to avoid the download mode?

I would like to set normal mode.  

Thanks,

Jackey

Hi Jackey

seems spi-nor boot boot from fuses option was programmed, as

described in Table 5-6. Serial-ROM Boot Fusemap  i.MX6DQ Reference Manual
http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf

There is no way to revert fuses state, still one can be able to use jtag for loading

and running images.

Best regards
igor
