[GitHub] [incubator-nuttx] masayuki2009 opened a new pull request #2380: tools: Fix nuttx-gdbinit for armv7-m with FPU

masayuki2009 opened a new pull request #2380:
URL: https://github.com/apache/incubator-nuttx/pull/2380


   ## Summary
   
   - Brennan reported the script does not work with nucleo-h743zi:otg_fs_host
   - Actually, the config uses FPU but the script did not detect it
   - The script assumed that the nuttx contains fpuconfig symbol
   - However, this assumption was incorrect
   - This commit fixes this issue by detecting FPU with tcb->xcp.regs
   
   ## Impact
   
   - Cortex-M targets
   
   ## Testing
   
   - Tested with lm3s6965-ek:discover (Cortex-M3)
   - Tested with spresense:wifi_smp (Cortex-M4F)
   - Tested with sim:smp (x86_64)
