Hi guys, I am working on a multi-threaded application that is compiled on Metaware C using Thread X API's on an ARC chipset platform. Using Seecode Debugger for debugging. I am faced with a strange problem here. There are some undeterministic times when, this application and ThreadX abruptly stops executing and except for the Power LED which stays on, nothing else works. That is there is no reponse at all. Not even the Thread X timer callbacks that I have registered get called.
If it was something like an invalid memory access we could expect the development board to reset ( restart). I have also checked the thread stacks using Seecode debugger, there is no overflow.
For memory managment, we are using TheadX byte pool and block pool service API's
We manage the thread stack memory requirements using a Block pool (created at init) and normal allocations if needed using a byte pool that we create at init. Initially we had used byte_pool for the thread stack memory also but we found a fragmentation based memory allocation problem on running the application for sometime. So we decided to use Block Pools for thread stack allocations. Would the choice me services for memory management be a reason we are having this abrupt hang/stop or the application and threadx ? Or what could be the reason.
I am hoping to get some ideas thrown at me about what might be the problem.
