Hi

Please help me to understand whether the monitor stack pointer has to be configured in the non secure mode in the boot sequence.
I understand that all the other stack pointers(usr, svc, fiq ,irq ) has to be configured for the non secure area.

But should i configure the monitor stack pointer also in non secure mode????
Please help

    @something..
    Does this mean that I have to initialise a pointer for sp_mon register in non secure mode?
    I do understand that i have to initialise stack pointer fro monitor in secure mode....but when cpu in monitor mode goes from secure to non secure, do we have to separetely initialise    SP_MON  register in non sec mode?
