Is this means OTP burning has been done ?

I cannot write SRK hash.
After the procedure in LSDK User guide 6.4.5, I ran debugger and it fails.
I turned off the device and boot from QSPI(non secure).
Checking SNVS state, I got this result on uboot.
=> md 1e90014 1
01e90014: 002b3c80  

 

Before, I had got this result.
=> md 1e90014
01e90014: 002b0088

 

Is this means that OTPMK and SRKH have already been burned ?

I understand that fuse burning is done only when WP=1 is set in input_fuse_file.

And I checked the fuse file, the flag was not set.

I use ls1046a-frwy.
