I trubling you much
I find it user_main .c file
// 0x40200000 is the base address for spi flash memory mapping, ESPFS_POS is the position
// where image is written in flash that is defined in Makefile.
#ifdef ESPFS_POS
espFsInit((void*)(0x40200000 + ESPFS_POS));
#else
espFsInit((void*)(webpages_espfs_start));
#endif
httpdInit(builtInUrls, 80);
Thanking you
