I hit a breakpoint so I thought I'd check tools here just to look around. This is running GUIX on ThreadX, SSP 1.2.0 on a S5D9 chip.
The bottom panel is what the RTOS Resrouces tab on E2 thinks is up with the stacks (I have stack marking turned on). The upper panel is what the TraceX5.2 thinks the stack usage is.
I don't see any resemblance between the two numbers myself.
A man with one watch knows exactly what time it is; a man with two has no idea.
