Ivan Grokhotkov 5a88f90a33 soc/rtc: warn if detected XTAL frequency does not match configured one
Since 9a8c0392, XTAL frequency is set to 40MHz by default, and users
of 26MHz boards need to select 26MHz manually. Most users are not aware
of this change, and existing getting started guides do not mention that
XTAL frequency needs to be set for some boards. So users are left with
garbage output from UART without any clue what to check.

This change adds a warning in case specific XTAL frequency was set, and
it does not match automatically detected one. This should help users
fix the issue.

include/soc 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
