<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">Thank you for the suggestion. I inspected the link step for the affected BSPs (e.g. aarch64/zynqmp_apu) and the link command does not appear to use an explicit linker script (no -T flag). The executable is produced by linking the RTEMS libraries (lrtemscpu, lrtemsbsp, etc.).</p>

<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">Based on this, the issue does not seem to be caused by missing linker script dependencies. Instead it appears that configuration state (such as RTEMS_SMP) is not reflected in the task signature. Since configuration changes do not modify compiler flags or source inputs, Waf considers previously compiled objects valid and reuses them.</p>
<p dir="auto" style="color: #3a383f; margin: 0;" align="initial">The configuration fingerprint approach ensures that configuration changes affect the compiler flags, which correctly invalidates existing objects and triggers a rebuild.</p>
