Hello,

I currently setting UCB setting for my project and I don't know what is the difference if I set User Code start address to Cached accessed address compare to non-cached access address in case BMI.HWCFG = Flash start = 111B)? Instruction cache is enabled in my project and as per my observation there is no difference between two case.

 

Thanks!

Hi Anh Nguyen Viet,

Your observation is correct, there is no difference whether the address is Cached/Non-cached. The Device would still start from the address configured in the BMHD. Hope this answers your question.
