[TW#26714] ESP32 WROVER Porting crash

[my-abousamra]

Environment

• Development Kit: [ESP32-Wrover-Kit]
• Kit version (for WroverKit): [v1]
• Core (if using chip or module): [ESP32-Wrover]
• IDF version (221eced.):
• Development Env: [Eclipse]
• Operating System: [Ubuntu]
• Power Supply: [USB]

Problem Description

I'm porting my application from ESP32_WROOM module to ESP32_Wrover to get use of external PSRAM
I enabled support for external RAM from menuconfig and ran the application then it crashed at freertos queue creation as following

`Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled.

When I disable PSRAM from menuconfig, it works properly

Expected Behavior

The code was running properly in ESP32 WROOM

Actual Behavior

It crashes in ESP32 WROVER

Besides that option in menuconfig you have also few others related to psram. Please check those 2:
Try to allocate memories of WiFi and LWIP in SPIRAM firstly. If failed, allocate internal memory
and SPI RAM access method (Make RAM allocatable using malloc() as well)

[my-abousamra]

I checked Try to allocate memories of WiFi and LWIP in SPIRAM firstly. If failed, allocate internal memory
and SPI RAM access method (Make RAM allocatable using malloc() as well) is already checked by default and problem still exist

[my-abousamra]

When I increase the value of this option Maximum malloc() size, in bytes, to always put in internal memory from 16384 to 116384 the problem doesn't occur and the application works properly but if I increased the size of the freertos queue to get use of the external PSRAM the problem occurs so I tried to increase the option value again but the menuconfig refused as it stated it is invalid value!

Works as GPIOs 8 & 9 was used!
