Thanks Yuri Muhin

 

 1- Using Single CST tool howmany times we can generate different Keys?

 2- In Imx8m OTP fuses are used to store the keys, here on generic question is that once i programmed the fuses, i cant use it for second time programming. so in this case im thinking that we are going to lost the security updates related keys. is it correct? or how we are overcoming the security updates related keys?

 3- Is there any optional memory for OTP fuses to store keys for development purpose. because once we programmed we cant use it for second time. 

 

Thanks in advance.
