esp32	component/bt: implement bluetooth modem sleep mode, one mode for BLE only and another for dual mode bluetooth	2018-05-19 15:37:26 +08:00
include/soc	Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity.	2018-02-02 17:11:06 +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
