documentation functions ROM esp32-c6

Postby watchdog40 » Wed Jul 08, 2026 2:02 pm

Hello
I cannot find the functions available in the ESP32-C6 ROM—corresponding to the function addresses listed in the `esp32c6.rom.libgcc.ld` file—within the documentation.

For example, I would like to know what the function `__ledf2 = 0x40000948;` does and how to call it (what parameters are required?).

Thanks.

https://gcc.gnu.org/onlinedocs/gcc-14.2 ... tines.html

In C, you invoke it like this:

Code: Select all

bool f(double a, double b) {
  return a <= b;
}
