How .bdat/.pdat files generated in NuttX/apps/builtin/registry/?

Hi guys

How below files are generated? This is an empty folder on git repo.

I only find the generation code for px4.bdat/.pdat , how about other files?

โ”œโ”€โ”€ nsh.bdat
โ”œโ”€โ”€ nsh.pdat
โ”œโ”€โ”€ px4.bdat
โ”œโ”€โ”€ px4.pdat
โ”œโ”€โ”€ sercon.bdat
โ”œโ”€โ”€ sercon.pdat
โ”œโ”€โ”€ serdis.bdat
โ”œโ”€โ”€ serdis.pdat
โ”œโ”€โ”€ sh.bdat
โ””โ”€โ”€ sh.pdat

Anyway, I have got it.

CMakelist+Makefile generate those .bdat/.pdat files. I update a web for introduction:PX4ๆจกๅ—่ฎพ่ฎกไน‹ๅไธ€๏ผšBuilt-Inๆก†ๆžถ_lida2003็š„ๅšๅฎข-CSDNๅšๅฎข
