CCS/TMS320F28388D: CPU2 BOOT from CPU1

NAGESH RK

Part Number: TMS320F28388D

Tool/software: Code Composer Studio

Hello,

I am using TMS320F28388D controller, i would like to know the status register values of CPU2 after booting in CPU1 using the register CPU2TOCPU1IPCBOOTSTS
.

From the TRM section 5.7.11.2 CPU2 Booting Status I see the values provided, but when I try to observe the values in CCS in debug mode after booting i see only zeros none have been set. How to know if the register values are set or not.

I have this code 'Device_bootCPU2(BOOTMODE_BOOT_TO_FLASH_SECTOR0);' basically I am expecting to see if the CPU2 has booted correctly or not

thanks,

Nagesh

Hello

Make sure CPU2 is actually running through boot ROM. You won't see this when loading the CPU2 app via CCS.

What you want to do it:

Load the apps to CPU1 and CPU2
Reset CPU2 via CCS and then click run
Run CPU1
View IPC reg via CPU1 and then you'll see the status values

Best regards

Chris

Hello

When connected to the device, in the CCS toolbar look for the "CPU Reset" icon

Best regards
