Hi Ronny,
I'm glad to hear your configuration issues are solved. I'm not sure what 'payloadSize' in your code is, but maybe that is incorrect. You could try passing sizeof(MyMsg) to MessageQ_alloc(). Also, the 'name' may be a problem. Is this pointing to a buffer in shared memory? You could try starting with an array for 'name' and see if that works.
Best regards,
Janet

Janet,
Thank you, your help has been very useful for me. I managed to solve the issues of the memory allocation using your advices.
I have a couple of questions regarding this, sorry Im a newbie.
How can I know if my program is using Shared Memory? As far as I know you have to put the next lines in the .cfg file:
var SHAREDMEM = 0x0C000000; var SHAREDMEMSIZE = 0x00200000; var SharedRegion = xdc.useModule("ti.sdo.ipc.SharedRegion"); SharedRegion.setEntryMeta(0, { base: SHAREDMEM, len: SHAREDMEMSIZE, ownerProcId: 0, isValid: true, name: "DDR3_DSP", });But how Can I assign a given "heap" to reside in the Shared Memory? Should I use the module ListMP of IPC?
The transports module "ti.sdo.ipc.transports.TransportShmSetup" uses shared memory as default? If not How can I configure my MessageQ application between ARM and DSP to use Shared Memory?
Thank you so much for your help, Im a bit confused about this.
Regards,
Ronny
