The colors feature is set by default whenever esp-backtrace is added without default-features = false somewhere in the dependency tree.

esp32 = print-float-registers

You must enable exactly one of the below features to support the correct chip:

Enables esp32 of optional esp-println, openocd-semihosting of optional semihosting

esp32c2

Enables esp32c2 of optional esp-println

esp32c3

Enables esp32c3 of optional esp-println

esp32c6

Enables esp32c6 of optional esp-println

esp32h2

Enables esp32h2 of optional esp-println

esp32p4

Enables esp32p4 of optional esp-println

esp32s2

Enables esp32s2 of optional esp-println, openocd-semihosting of optional semihosting

esp32s3 = print-float-registers

Enables esp32s3 of optional esp-println and openocd-semihosting of optional semihosting
