ESP32 camera initialization failed #339
Description
I'm trying to initialize the camera using the same code as provided in examples, but I end up in failure while trying to allocate memory:

I'm using M5stack timer camera ( http://docs.m5stack.com/en/unit/timercam_f ) which has PSRAM of 8MB, so allocation of 384KB should not be problem I think.
SDK config related to ESP32 and SPI RAM is as below:
ESP32-specific:
CONFIG_ESP32_ECO3_CACHE_LOCK_FIX=y
CONFIG_ESP32_REV_MIN_0=y
CONFIG_ESP32_REV_MIN=0
CONFIG_ESP32_DPORT_WORKAROUND=y
CONFIG_ESP32_DEFAULT_CPU_FREQ_160=y
CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ=160
CONFIG_ESP32_SPIRAM_SUPPORT=y
SPI RAM config:
CONFIG_SPIRAM_TYPE_AUTO=y
CONFIG_SPIRAM_SIZE=-1
CONFIG_SPIRAM_SPEED_40M=y
CONFIG_SPIRAM=y
CONFIG_SPIRAM_BOOT_INIT=y
CONFIG_SPIRAM_IGNORE_NOTFOUND=y
CONFIG_SPIRAM_USE_MALLOC=y
CONFIG_SPIRAM_MEMTEST=y

CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP=y
CONFIG_SPIRAM_MALLOC_RESERVE_INTERNAL=32768

Can someone please help.
