Sample Code / Setup for M0+ BLE ( CM0P_BLESS )

[matthiasb]

Hello,
i'm trying to use the CM0+ Core for BLE. I have chosen the BLE FindMe Example for a starting point and added a custom linkerscript. But as soon as I specify FLASH_CM0P_SIZE above 0x2000 , the resulting executable doesn't run on my CYC8CPROTO-063-BLE.  

Memory Map:

ram (rwx) : ORIGIN = 0x08008000, LENGTH = 0x3F800
flash (rx) : ORIGIN = 0x10000000, LENGTH = 0x100000

I searched a lot on the web and on this site and didn't find an example for using the CM0P_BLESS component.

A complete example on how to set up the CM0P_BLESS component would be very helpful.

Thank you,
 Matthias

Hello,

Please refer to the section 'Complete BLE Protocol Dual CPU Mode' (in Configuration Considerations) in the PSoC6 BLE Middleware library.

Thanks,

Hello,

I have. But i cannot get it to work with this information. Don't you have a simple example project code ?

Thank you,

Hello, 

Please refer to the link for updating the ram, flash, and FLASH_CM0P_SIZE values in the linker script for CM4. In makefile, to operate in Dual CPU mode, add the COMPONENT_BLESS_HOST_IPC and COMPONENT_CM0P_BLESS directory as shown below.

COMPONENTS+=BLESS_HOST_IPC CM0P_BLESS
DISABLE_COMPONENTS+=CM0P_SLEEP

Thanks,

P Yugandhar.

Yes, I have read all the links but i can't get it to work only with this information. My first try was just to replace the components like in your snippet. After that I had to add a linker script with "FLASH_CM0P_SIZE" set to 20000 . But this just doesn't execute on my devboard.

Once again a working example would be great!

Hello, 

 Could you please try changing the default(bsp) linker script file ?

Please find the attached project.

Thanks,

this linker script worked (after modifying the Makefile to use this script). thank you very much!
