Ivan Grokhotkov f11ad0c904 soc/rtc: fix spurious warnings about XTAL frequency on startup ... 1. Make sure that 8MD256 clock used to estimate XTAL frequency is enabled before trying to use rtc_clk_cal_ratio. This fixes "Bogus XTAL frequency: 0 MHz" warnings after software reset. 2. Don't call rtc_clk_xtal_freq_estimate if XTAL frequency is already known. This reduces startup time after deep sleep or software reset. 3. Compare known XTAL frequency and estimated one before printing a warning. This fixes "Possibly invalid CONFIG_ESP32_XTAL_FREQ setting (40MHz). Detected 40 MHz." warnings.		2017-10-26 19:53:53 +08:00

esp32	soc/rtc: fix spurious warnings about XTAL frequency on startup	2017-10-26 19:53:53 +08:00
include/soc	Add logic to make external RAM usable with malloc()	2017-09-28 17:17:50 +08:00
test	soc: add source code of rtc_clk, rtc_pm	2017-04-11 15:45:54 +08:00
component.mk	Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet.	2017-09-04 12:05:49 +08:00
