Is my DevBoard LX2160A with the secure boot fuse blown?

[johan_duque]

Hi,

I'm checking the User guide for LSSDK 19.09 and in the page 57 saiys:

• Check initial SNVS state

md 1e90014
88000900

The second nibble indicates that the OTPMK is not blown

But if I execute the command, the output is like this:

=> md 1e90014
01e90014: 00000000 00000000                      ........

Does it means my board has the secue boot fused?

Please provide as textual attachment complete U-Boot booting log and output of the "md 1e90BFC" command.

Hi,

I'm asking this because I've followed the guide to flash an image built with flex-builder and installed in a SD card with flex-installer and it doesn't boot.

I'm attaching three files:

- fullboot_error.txt -> This contains the whole boot until it fails trying to load the init

- uboot-md.txt -> Contains exactly what you asked for.

- uboot-printenv.txt -> Contains the output of printenv of u-boot

Let me know if you need anything else, thank you very much.

Was the board operational and capable to boot in factory-new state?

Yes, it's operational and can boot "TinyLSDK" boot, but not mine.

Please attach detailed description and logs corresponding to the image building with flex-builder and installation on SD card with flex-installer.
