Boot The Cortex-A9 MPCORE With Linux+uC/OS-II AMP

Author:Fourier Email:[e-mail]

 

AMP:(AsymmetricMultiple Processing)

Scenario:cpu core 0 run Linux, cpu core 1 run uC/OS-II RTOS. HDMI display panellink to Linux, LCD display panel link to uC/OS-II RTOS.

 

Platform:

MarsBoard(freesclae i.mx6 dual Coretex-A9 core, 1GB 64bit DDR3)

Panda Board(TIOMAP4460 dual Cortex-A9 core, 1GB 32bit DDR3)

Altera SoC EVMBoard(dual Cortex-A9 core, (512MB+256MB ECC) DDR3 on HPS, 512MB on FPGA)

AMP Port:

Linux SMP bootprocedure is not mention here, For detail about the Linux SMP boot procedure pleaserefer to the document here,http://www.linux-arm.org/LinuxBootLoader/SMPBoot.I just move the boot secondary procedure from Linux to U-boot as figure 1 in the AMP implementation, and figure2 describe the GIC relationship between two core and physical memory layoutbetween Linux and uC/OS-II.
