Hi,
I am running ti-processor-sdk-linux-rt-am57xx-evm-06.03.00.106 with Linux running on A15 and RTOS on IPU1 and DSP1.
So far I have followed the ex02_messageq and the big data example to gather information on how to implement IPC, shared memory and GateMP etc.
In order to get GateMP working I added a shared memory region as follows:
/* shared region configuration */
var SharedRegion = xdc.useModule('ti.sdo.ipc.SharedRegion');
/* configure SharedRegion #0 (IPC) */
var SR0Mem = Program.cpu.memoryMap["SR_0"];
SharedRegion.setEntryMeta(0,
new SharedRegion.Entry({
name: "SR0",
base: SR0Mem.base,
len: SR0Mem.len,
ownerProcId: MultiProc.getIdMeta("DSP1"),
cacheEnable: true,
isValid: true
//createHeap: true
})
);
Then I added a custom resource table and on DSP1 side GateMP worked fine.
Now when I compile the same application for IPU1 and try to run it, I get the following error:
ti.sdo.ipc.GateMP: line 1176: assertion failure: A_noHeap: Region has no heap
I made sure that the same shared memory region is added on IPU1 side and tried it with different ownerProcIds and createHeap: true, but nothing solved the issue.
The only way to be able to create a GateMP instance is if I add GateMP_Params.sharedAddr pointing to the shared memory.
If I do this I can use GateMP on IPU1. Although I am curious why on DSP side a heap on shared memory is created, meanwhile on IPU side it seems that no heap is created for regionId: 0.
How can I enable the heap on shared memory for IPU1?
Thank you for your help.
Best regards,
Nicolas Rausch
