acassis opened a new pull request, #21552:
URL: https://github.com/apache/nuttx/pull/21552

   ## Summary
   
   The diagnostic PendSV handler (attached with CONFIG_DEBUG_FEATURES)
   panics.  PendSV is only dispatched to it when
   CONFIG_ARCH_HIPRI_INTERRUPT is set, and then PendSV is not an error:
   the OS pends it to deliver signals and a high priority interrupt may
   use it to get back into the OS.  Do not attach it in that case, as the
   stm32h7 and stm32l4 ports already do.
   
   ## Impact
   
   Users will get ethernet working when the board initializes without an 
Ethernet cable connected and plug it later.
   
   ## Testing
   
   On dd-ec300 using telnet (started without ethernet cable and plugged later)
   
   ```
   $ telnet 172.22.2.100
   Trying 172.22.2.100...
   Connected to 172.22.2.100.
   Escape character is '^]'.
