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
    }
}

Rebooting...

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.

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); }
    }
}

I have checked existing issues, online documentation and the Troubleshooting Guide

[X] I confirm I have checked existing issues, online documentation and Troubleshooting guide.

This is a different ESP from the same modell. Heavy PS-ram use. Ps ram is allocated on class creation, but the class creation is not at startup, but inside setup() so the ps ram is inited.

Plus the sketch uses ps ram before this error without issue.

My sketch initializing tasks one by one at startup.

void initTasks(){
    // Every init is a task creation.
    hsh_modbus.init(-1,3,MODBUS_SYS_STACK_SIZE);
    vTaskDelay(100);
    hsh_Server.init(1,2,SERVER_SYS_STACK_SIZE);
    hsh_Performance.init(1,2,PERFORMANCE_SYS_STACK_SIZE);
    hsh_timeSystem.init(1,2,TIME_SYS_STACK_SIZE);
    zones.init(1,3,ZONES_SYS_STACK_SIZE);

    xTaskCreateUniversal(shaderTask, "HSH_SHADER_TASK", 4000, NULL, 4, NULL, 1);
}

The crash happens in the zones task at it's setup. Inside this task i read a config file from LitleFS in JSON format and start to loop over it. For every component inside the JSON file i create a class dynamically like this (Using ArduinoJSON):

SpiRamJsonDocument zonesObj(ZONES_OBJ_SIZE);
DeserializationError error = deserializeJson(zonesObj, (const char *)zones, ZONES_OBJ_SIZE);
if (error) { return; }
JsonObject zones = zonesObj.as<JsonObject>();
for (JsonPair zoneRef : zones) {
    const char* zoneID  = zoneRef.key().c_str();
    JsonObject zone     = zones[zoneID];
    boolean isZone      = zone["isZone"].as<boolean>();
    if( !isZone ){ continue; }

   JsonObject lightsObj   = zone["lights"].as<JsonObject>();
    if( !lightsObj.isNull() ){
        for (JsonPair componentRef : lightsObj) {
            if( lightCount >= MAX_LIGHTS ){break;}
            const char* componentID  = componentRef.key().c_str();
            JsonObject component     = lightsObj[componentID];
            lightsArray[lightCount]  = new lightSystem();
            if( !lightsArray[lightCount] ){ continue; }
            lightsArray[lightCount]->update(component,componentID,lightCount,zoneID);
            lightCount++;
        }
    }
}

As you can see in the error log, it start to create the light classes and suddenly it crashes with this error.

Light class constructor and descructor looks like this:

// Constructor
void lightSystem::allocateResources(){
    outputs  = (char *) ps_malloc (IO_SIZE * sizeof (char));
    inputs   = (char *) ps_malloc (IO_SIZE * sizeof (char));
    triggerInputs = (char *) ps_malloc (IO_SIZE * sizeof (char));

    id       = (char *) ps_malloc (IDS_AND_NAMES_SIZE * sizeof (char));
    zoneID   = (char *) ps_malloc (IDS_AND_NAMES_SIZE * sizeof (char));
    name     = (char *) ps_malloc (IDS_AND_NAMES_SIZE * sizeof (char));

    if( outputs == NULL || inputs == NULL || triggerInputs == NULL || id == NULL || zoneID == NULL || name == NULL ){
        Serial.println("[LIGHT_SYS] - Failed to allocate resources");
    }
}
// Descurtor
void lightSystem::freeResources(){
    free(id);
    free(zoneID);
    free(name);
    free(outputs);
    free(inputs);
    free(triggerInputs);
}

LightsArray holds the class pointers. It looks like this:

extern lightSystem* lightsArray[MAX_LIGHTS];

What could be the problem?

me-no-dev commented 1 year ago

@zekageri this happens only with one particular board, but not with any other one, correct? Even though both traces are the same, the cause looks to be the same.

@igrr do you have any pointers what could be going wrong with PSRAM? This seems to be an ECO3 ESP32, so could it be the PSRAM chip is failing in some way?

zekageri commented 1 year ago

This is both an ESP32-Wrover with 8mb ps ram and 16mb flash. Both chip is the same type. I ditched the other one because of this error. I thought that the ext ram died in one and replaced the chip. But this one does it too.

This bug should be fixed in IDF by https://github.com/espressif/esp-idf/commit/b43e777e0a25fecd4652d5282427366fadae8b1d (available on release/v4.4 branch, will be part of v4.4.3)

But i did not try to allocate 0 byte

@zekageri if you check out manually Arduino core master branch, it's supposed to be solved. Our current master use ESP-IDF 4.4.3.

Thank you. I will test it!

基于esp-idfv4.4.4条件下使用esp32S3,启用external spiram 使用nimble client功能下在BLE_GAP_EVENT_NOTIFY_RX事件中有接口用于处理接收的数据，将接收的数据解析打包push到队列中，再由其他其他线程将队列中的数据上报到云；该接口在蓝牙数据上报频繁时会在malloc是出现报错assert failed: block_trim_free heap_tlsf.c:371 (block_is_free(block) && "block must be free")，但是该接口在上报频率较低或者该接口在串口读取数据处理从未报过该错误。其中malloc也测试过使用片内和片外ram,均出现同样错误，而且malloc不会执行到返回null;直接在调用malloc()或者heap_caps_malloc(）内部就已经开始报错了

assert failed: block_trim_free heap_tlsf.c:371 (block_is_free(block) && "block must be free")

I can also report that still this happens to me on a WROVER-E 8MB with IDF version ESP-IDF v4.4.3-347-g9ee3c8337d.

It happens more infrequently when SPIRAM frequency is at 40Mhz
