IPC in LPC4300

katisr — Sun, 30 Jul 2017 09:04:46 GMT

Hello all,

I am new to LPC4300 and multicore. I saw few examples in LPCOpen. There were examples with RTOS and without. As a beginner it is confusing if I should use RTOS or not. I have attached the link where I found the examples LPCOpen Software for LPC43XX|NXP . My question is , is RTOS necessary for working in dual-core mode ? I just wanted to experiment the IPC with simple examples like M4 turning ON LED and M0 turning it OFF.

Hi,

No, it is no necessary to work with a RTOS, however it is easier to manage both cores using the RTOS.

Please check the below document

https://community.nxp.com/docs/DOC-330811

In addition I suggest to check the application note AN11177 Inter Processor Communication,

AN11177: Inter Processor Communications.

this appnote provides information about:

The API implementation for dual core communication on LPC43xx targets
How to include or exclude functionality by means of a platform-wise configuration file
System level settings and debug options to be aware of when changing the

configuration
