Description

External ram memory allocation assert fail. Happens on one esp32-wrover-e but not on others with the exact same sketch. How to capture the exception?

Sketch

// Crash is at total random allocations but all looks like this ( using ArduinoJSON ):

#include <Arduino.h>
#include <ArduinoJson.h>

struct SpiRamAllocator {
    void* allocate(size_t size) {return heap_caps_malloc(size, MALLOC_CAP_SPIRAM);}
    void deallocate(void* pointer) {heap_caps_free(pointer);}
    void* reallocate(void* ptr, size_t new_size) {return heap_caps_realloc(ptr, new_size, MALLOC_CAP_SPIRAM);}
};
using SpiRamJsonDocument = BasicJsonDocument<SpiRamAllocator>;



SpiRamJsonDocument data(DATA_SIZE);


// Example function when using SpiRamJsonDocument:


#define GRAPH_SIZE 20000
char * graph;
graph = (char *) ps_malloc (GRAPH_SIZE * sizeof (char));  

void thermSystem::trimGraph(){
    // Check if previous allocation was a success.
    if( graph == NULL ) { Serial.println("Failed to allocate memory for graph data"); return; }

    SpiRamJsonDocument allGraphData(GRAPH_SIZE);
    DeserializationError error = deserializeJson(allGraphData, (const char *)graph, GRAPH_SIZE);
    if (!error) {
        // Get only the graph where the zoneID matches.
        JsonObject graphData = allGraphData[zoneID];
        if( !graphData.isNull() ){
            if( serializeJson(graphData, graph, GRAPH_SIZE) ) {
                #if THERM_DEBUG
                    Serial.printf("Trimmed graph\n");
                #endif
            }
        }
    }else{
        #if THERM_DEBUG
            Serial.printf("Failed to deserialize ALL therm graph. Error: %s\n",error.c_str());
        #endif
    }
}

Other Steps to Reproduce

I'm using ArduinoJsonAllocator for a lot of JSON serialization / deserialization. This error happens on only one esp32 ( tested on 5 chip with the exact same parameters )

I can not capture this exception because it happens internally.

Error: assert failed: block_trim_free heap_tlsf.c:377 (block_is_free(block) && "block must be free")

I have found two issues that stated that problem but it seems to me that it was patched a long time ago.

1. One case in github
2. Other case in github

I have a check in setup which looks like this but it did not help:

void setup() {
    Serial.begin(115200,SERIAL_8N1,DEBUG_RX,DEBUG_TX);
    vTaskDelay(1000);
   
    // The following line evaulates to true.
    if( !psramFound() ){
        Serial.println("Something wrong with the external ram.");
        while(1){ vTaskDelay(1); }
    }
}
