Uninitialized variables in ThreadX module #2

Closed smmanu closed 2 years ago

smmanu commented 2 years ago

Setup

Keil uvision 5.35, ac6

Description

Variables in a ThreadX module do not get their initial values as expected. Static or global variables are not initialized to 0 and variables in general do not get the initial value assigned in their definition.

Additional context

The call that is supposed to perform the C runtime initialization of a module is commented out in txm_module_initialize.S (line 73). This is not specific to stm32u5xx or cortex-m33 since the same line is also commented out in other ports to ac6. The code seems to be the same in the Azure RTOS repo, so perhaps this should be reported to them?
