Hi Padmesh,

> I wanted to know if there is any way in retaining the activity of the executable in cortex M4 even after the board is reset ? How do we achieve it ?

What exactly are you referring to when you mean by the board is reset? Are you referring to the power on reset (PORZ)?

> Is there any way of invoking the M4 core without fully booting (i.e without booting the linux OS) the a15 core?

The M4 can be loaded directly from the boot loader using the Early Boot feature. A detailed description of the support in the SDK is captured in this page: processors.wiki.ti.com/.../Early_Boot_and_Late_Attach_in_Linux and it is also recommended that you refer to the Software Developers Guide (processors.wiki.ti.com/.../Processor_SDK_Linux_Automotive_Software_Developers_Guide) for some additional insights into the Late Attach feature.

Hi Karthik,

With reset what I meant is the power cycle.

Also for the 2nd question, are there any u-boot files in processor sdk having the early boot feature ?

Regards,

Padmesh

Is the code being executed in the OCMC RAM in this procedure ?

Also, Is the same (the case after reset) true when an IPC example is run between M4 and A15 ?
