[AKL123]

Hi,
I've the board EVB-SCMIMX6SX. It has Coretex-A9 and Cortex-M4.
I would like to know:

1- how to get the status of both CPUs

2- how to enable/disable Cortex-M4

Thanks a lot

Hi @JosephAtNXP 
Thanks for your reply. However, the guide's link is not working. It gives the error "Article not found"

Hi @AKL123,

Thanks for pointing that out, in that case, you could download 6SX FreeRTOS BSP, install it under C:\NXP\ and review the docs under doc\, also have the Linux Reference Manual and Linux Users Guide handy.

Hi,

Thank you for your interest in NXP Semiconductor products,

In this guide, a Cortex-M demo is explored and you can see how Cortex-M is started, the demo doesn't stop the Cortex-M.

The boot process is reviewed in reference manual:

13.5 Cortex-M4 Boot Requirements
• Cortex-A9 always boots as the primary core.
• Cortex-M4 does not have a boot ROM and at POR is not provided a clock
• Cortex-A9 user code is responsible for the following:
• Loading and authenticating Cortex-M4 firmware by HAB API or with CortexA9 firmware together as a unified image by boot ROM.
• Launching the Cortex-M4 by enabling its clock and clearing its reset bit in SRC
(See System Reset Controller Chapter for more details).
