my gdb script
```
file target/kairos-ngcmio/dist/default/final.elf
add-symbol-file target/kairos-ngcmio/dist/default/kernel
add-symbol-file target/kairos-ngcmio/dist/default/lora_modem
add-symbol-file target/kairos-ngcmio/dist/default/jefe
add-symbol-file target/kairos-ngcmio/dist/default/sys
add-symbol-file target/kairos-ngcmio/dist/default/usart_driver
```

I suppose I need to examine the elf file symbols directly
