AWR1843BOOST: No privilige mode on start up

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843, AWR1642

Hello,

I am writing my own project for AWR1843 boost board using CCS studio. I would like ARM Cortex R4 to work in Privilige mode on power up. But as of now it is in USER mode, because of this I ma not able to go to Privilege /system mode and also not able to generate an interrupt.

Could you please help me with the steps to a include init config file in CCS?

Thanks & Best Regards,

Yeshaswini

    Hi Yeshaswini,

    Sorry for the delay in my response. We have a nonos lab for AWR1642 (which can run as is for AWR1843 as well). In the lab, _sysSvcEntry_ in sys_startup.asm puts the core in supervisor mode. Could you use this as reference in your own code?

    Also, can I ask about the setup that you have right now? How are you testing this at startup? Is it through an application (perhaps an OS based application), or is it startup assembly code?

    Thanks & Regards,
