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. 2017-07-20 08:26:35 +00:00			`LIBC_PATH := $(COMPONENT_PATH)/lib/libc-psram-workaround.a`

newlib: Provide library name for ROM libc object files linked as PSRAM workarounds Works around bug reported on forums where any source file ending in lock.c or creat.c was being linked to IRAM. https://esp32.com/viewtopic.php?f=13&t=8909&p=37362#p37362 Also moves all related functionality to newlib component. 2019-01-22 03:49:17 +00:00			`COMPONENT_ADD_LDFRAGMENTS := esp32-spiram-rom-functions.lf`

newlib: add "full" formatting support, add missing functions - add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM. - fix linker error for fmod, fmodf, atof, atoff - update tests 2016-11-07 10:43:29 +00:00			`LIBC_PATH := $(COMPONENT_PATH)/lib/libc_nano.a`

Add --warn-undefined-variables to MAKEFLAGS Fix warnings where undefined vars are used. Make Kconfig emit "FOO=" for unset bool options To ensure make variables are always defined, even if empty. When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.

newlib: disable some optimizations for syscalls.c Don’t allow the compiler to convert malloc + memset into calloc, causing a recursive call in _calloc_r. Fixes crash when building with -O2 optimization level. 2018-11-22 04:19:49 +00:00
