Eclipse ThreadX
An Azure embedded development suite including a small but powerful operating system for resource-constrained devices.
We do not have an example that calls file_load.

Hello, is there any example of ThreadX module manager calling the txm_module_manager_file_load() possibly running on ARM M7 ?
Thank you, best regards

2021-04-30T06:47:43.713+00:00 Hi Scott, thanks! to be more specific my issue is that the module seems not scheduled if loaded from file calling txm_module_manager_file_load(), the same module works perfectly if executed in place calling txm_module_manager_in_place_load(). No errors or callbacks are generated, simply the module seems not scheduled, the processor i'm using is STM32H743ZI.
Perhaps some specific memory settings through linker script are needed to execute modules from RAM?
Thank you , regards -

2021-05-05T12:57:01.58+00:00 Hi Scott, the module seems loaded successfully as the <txm_module_manager_file_load( &my_module, "my module", &ram_disk, "TEST.bin");> return TX_SUCCESS but when the scheduler try to start it with the instruction <BX lr > the <module_fault_handler() > function is called if MPU is enabled in module preamble <DC32 0x00000007 >, if MPU is not enabled the module is simply not scheduled.
The same module loaded calling <txm_module_manager_in_place_load(&my_module, "my module", (VOID *) 0x080F0000);> is scheduled properly.
Thank you, best regards -

2021-06-16T02:17:59.107+00:00 Where is the module placed when using the file load function? And what are the MPU settings? Can you take a screenshot of the module struct with the MPU settings expanded?
