Hi Alex

Will get back to you soon on this

But, what if I want to use multiple SDK projects and enable IPC_Notify

The easiest way would be to take up the IPC Notify example and start from there if you want to use all the four cores,

AlexWalton42 said:

n addition, each of the SDK projects begin with a system_init() and board_init(). Should I delete the repetitive init() functions from all but one SDK project?

system_init() and board_init() are required for every core for DPL, clocks, PinMux, Uart, peripheral initialisations.

I dont understand what do you mean by repetitive, Could you please elaborate it?

I'd greatly appreciate any other guidance/recommendations for integrating several SDK projects into a system project.

For How many cores do you need a system project?

System project just converts multiple rprc images of different cores into single app image. You can do it through a command also as shown below:

I highly recommend going through the below thread for this information -

Okay, I will do this. Do you foresee any possible issues copying over all of the project files and properties over to the IPC notify project? Besides the files and project properties, will I need to change anything else?

I understand that system_init() should be called in each project because it initializes the core and system drivers. But, I'm concerned about the board_init() since it does board related driver initializations. Wouldn't the board initializations only need to be done once? By recalling board_init(), I'd assume that the hardware on the board would be initialized more than once and may cause issues. Is my understanding incorrect here?

I'm using two cores. I'm not using the system project, so I build and load the images individually. One of the projects I'm using has unique build steps with the PRU and doesn't currently work with the system project. In the future, I'd like to convert to modify the build steps or the system project.

looking into it will get back soon

Could you check what board initialisations are you doing in your project
Usually board init is empty and it will be based on your syscfg file of your core.

Does it make sense?

I dont see any issues,
you will have to remove the IPC Notify for the cores you are not using.

YOu can use example project if you require only two cores, instead of IPC notify.

Hi Sri,

Thank you for the guidance. For my application, I need the R5F_00 to notify the R5F_01 once a non-cacheable memory block is full. This memory block can be up to 16kB for my application, so I need to send a pointer to the memory location in the IPC message. Can you please provide instructions on how I can modify this example to implement this?

I'd greatly appreciate your help here. Thank you!
