Gunar Schorcht	528512d9af	cpu/esp32: activate automatic XTAL detection ... ESP32 can be clocked with either a 40 MHz or 26 MHz crystal. Since most boards use a 40 MHz crystal, the configuration was previously fixed to a 40 MHz crystal. This commit changes the crystal from 40 MHz to automatic detection, allowing boards with a 26 MHz crystal like the Sparkfun ESP32 Thing DEV to be used.	2020-01-09 15:34:18 +01:00
Gunar Schorcht	91496b3cba	cpu/esp32: add bootloaders without startup info ... To reduce the information that are printed at the console during the startup, special bootloaders are required that suppress the outputs which are only informational. The according bootloader has to be selected during the make process.	2019-11-28 18:59:09 +01:00
