fatfs crashes after some time

Postby Weskrauser » Tue May 21, 2024 2:17 pm

Hello!

I am currently working on sdio logging on SD card with esp32s3. I'm using platformio with :
- platform = espressif32 @ 6.6.0
- framework-arduinoespressif32 @ 3.20014.231204 (2.0.14)
- toolchain-xtensa-esp32s3 @ 8.4.0+2021r2-patch5

My system uses 2 buffers and one task per core for logging purpose:
- One shared short buffer protected by a mutex is feeded at 500 Hz by the main task on core0.
- At 50Hz the second task on core1 grab the mutex, copy the short buffer content in a ringBuffer (from https://github.com/greiman/SdFat/blob/m ... /RingBuf.h), write it to the SD file and flush the result every 10 seconds.

Fast task on core0:

Code: Select all

// Update temp buffer if it is unused
    if (xSemaphoreTake(xSemaphore, (TickType_t)1) == pdTRUE)
    {
        // Write new data frame to short buffer 
        xSemaphoreGive(xSemaphore);
    }
Slow task on core 1:

Code: Select all

if (xSemaphoreTake(xSemaphore, (TickType_t)10) == pdTRUE)
    {
    	// Copy this short buffer to big ringBuffer 
        bytesWritten = ringBuffer->write(tempFastBuffer, idxTempFastBuffer);
        xSemaphoreGive(xSemaphore);        
        idxTempFastBuffer = 0U;
    }
The part of code that crashes in this slow task:

Code: Select all


        for (size_t i = 0; i < nbSectorsToWrite; i++)
        {
            // Write one sector from RingBuf to file
            mRingBufferBatchSize != ringBuffer->writeOut(mRingBufferBatchSize);
        }
This systems works well for around 310-340s with really consistent logs results. Then I face Guru meditation with two kind of errors:

Do you have any idea the reason behind this crash?

I tested the possibility of empty buffers but it does not seem to be the case.

Thanks in advance!
