Hello,

 

I want to boot cortex-M4 on iMX6-SoloX. From "i.MX 6SoloX Applications Processor Reference Manual", section 13.5 as below:

 

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 ROM is responsible for the following:

• Loading and authenticating A9 bootloader and initiating Cortex-M4 firmware as a unified image

• Setting up Cortex-M4 initial exception table in TCRAML

• Launching the Cortex-M4 by enabling its clock

 

What is TCRAML? What is the boot address of cortex-M4? Do you have document to describe how to boot cortex-M4?

 

Thanks,

Miles
