MX6UL: Secure boot - realloc(): invalid pointer Error

sreenivasu — Thu, 11 Apr 2024 14:46:21 GMT

Hello

I am trying to perform secure boot on MX6UL board, As per NXP documents , I am able to generate the Key infrastructure properly and able to create a csf.txt file without any errors.

But While running the command ./cst --o csf.bin --i csf.txt from cst folder/cst/linux64/bin

I am getting the error

realloc(): invalid pointer
Aborted (core dumped)

Help me out how to proceed further and how to use the IVT tool and further steps

Contents of csf.txt file
