Guru Meditation Error trigger by nvs_flash_init when activated SystemView Tracing (IDFGH-7571)

## Problem Description

In our project we would like to do system Behavior Analysis with SEGGER SystemView. For this purpose from idf.py menuconfig I'm activated:

Component config --> Application Level Tracing --> Data Destomatopm 1 --> (JTAG) 
FreeRTOS SystemView Tracing --> SystemView Tracing Enable.

Before activated this option in idf.py menuconfig the system is working fine.

Once the above options in menuconfig  are save and the project is build  and flash system start to enter in the critical error:

_Guru Meditation Error: Core  0 panic'ed (Cache disabled but cached memory region accessed)._

From the trace I can see that nvs_flash_init is trigger this panic error. In the project we are using custom partition table. 

If NvS component is not used the panic error is not any more present and I'm able to drop me .SVDat from the JTAG.

See the log file below. Sdconfig file, partition table and .elf file are upload here: https://github.com/nikidimitrow/idf-report-crash

In this peace of code is where Init of partition happen:

```
void NVWrapper_Init(void)
{
 
	/* Initialize Partitions */
	if (NVWrapper_InitPartitions() == ESP_OK) {
	    NVWrapper_PartitionsInit_ValidityFlag = true;
	} else {
	  NVWrapper_Log(E, "Partitions initialization: FAILED !");
	}
	/* Open  Partitions */
	if (NVWrapper_OpenPartitions()  == ESP_OK) {
	    NVWrapper_PartitionsOpen_ValidityFlag = true;
	} else {
	  NVWrapper_Log(E, "Partitions opening: FAILED !");
	}

	if ((true == NVWrapper_PartitionsInit_ValidityFlag) &&
	    (true == NVWrapper_PartitionsOpen_ValidityFlag))
	{
	    /* Set state to initialized */
	    NVWrapperInitialized = true;
	    NVWrapper_Log(I, "NVWrapper initialization: OK !");
	} else {
	    NVWrapper_Log(E, "NVWrapper initialization: FAILED !");
	}
}
```

**NVWrapper_InitPartitions function**

```
static esp_err_t NVWrapper_InitPartitions(void)
{
	esp_err_t retVal = ESP_FAIL;
	NVWrapper_PartitionsId count = 0;

	NVWrapper_Log(I, "Start Partition Initialization...");
	for (count = 0; count < PartitionsCount; count++) {
		retVal = nvs_flash_init_partition(Partitions[count]);

#if (PARTITION_REINITIALIZATION == E_ON)
		if (retVal == ESP_ERR_NVS_NO_FREE_PAGES || retVal == ESP_ERR_NVS_NEW_VERSION_FOUND) {
			NVWrapper_Log(W, "Init of '%s' partition failed, it will be erased and re-initted ! [Error: 0x%X]", Partitions[count], retVal);
			if (ESP_OK != nvs_flash_erase_partition(Partitions[count])) {
			    NVWrapper_Log(W, "Failed to erase the partition with Id %d [Error: 0x%X]", Partitions[count], retVal);
			}
			retVal = nvs_flash_init_partition(Partitions[count]);
		}
#endif
		if (ESP_OK == retVal) {
			NVWrapper_Log(I, "Initialization of partition '%s' with id %d : OK !", Partitions[count], count);
		} else {
			NVWrapper_Log(E, "Initialization of partition '%s' with id %d : FAILED ! [error: 0x%X]", Partitions[count], count, retVal);
		}
	}
	NVWrapper_Log(I, "... Partition Initialization Done !");

	return retVal;
}
```

This are the argument that are passed to nvs_flash_init_partition(Partitions[count]);

```
static const tChar Partitions[PartitionsCount][NVS_NAMES_MAX_SYMBOLS] = {
		"prod",     /* ProductionPartition  */
        "safe",     /* SafeNVPartition      */
        "nvs",      /* NVSPartition         */
        "appl",     /* ApplicationPartition */
		"shared"    /* SharedPartition      */
};
