"I have increase of task stack size to 50000 to make it work .still write to sd card. empty file."

Increasing the stack size should only make it worse.

[snahmad75]

Full logs. Out of memory. My task stack size is = 25000.
What is the solution.

I can avoid using libCurl and use socket http get file chunk by chunk and write SD card as file.
Later on I need HTTPS. I guess kolban Https C++ class will do the job.

[fly135]

A stack size of 25K is using up a lot of memory. Granted if you only have one task that might be OK. Do you have a reason for such a large stack? Maybe try 6K, or tell us what you are putting on the stack that makes the need so high.

Put this in your app so we can see what you are dealing with...

Code: Select all

  UBaseType_t uxHighWaterMark = uxTaskGetStackHighWaterMark( NULL );
  printf("Stack free: %d\r\n", uxHighWaterMark);
  printf("Internal Heap free: %d\r\n", heap_caps_get_free_size(MALLOC_CAP_INTERNAL));
  printf("Heap free: %d:%d\r\n", heap_caps_get_free_size(MALLOC_CAP_8BIT),
          heap_caps_get_free_size(MALLOC_CAP_32BIT));

Yes A stack size of 25K is using up a lot of memory. I already have few others task needs max of 12000 stack size.
Already consume too many ram. RAM size on esp32 is 512kb. I get of main start 256 kb checked by heap stats as first line in main.
I will need heap and stack for later for secure http. not used yet.

I was just trying to make libCurl works without giving me out memory error. I can using simple http C or C++ function to get http files one by files and write to sd card as files by avoiding libCurl.

I managed to use OTA example to do http get chunk by chunck for my binary image. I guess i can simple way for each web files and write to sd card.

I will try stack and heap stats in my program tomorrow and let you know results.

Thanks for your input.

Hi,

check logs below. any idea. Let me try libCurl example as well.

Yes A stack size of 25K is using up a lot of memory. I already have few others task needs max of 12000 stack size.

In my experience you are using too much stack and that is why I think you are running out of memory. How do you know you need that much stack for your tasks? I'm not using anywhere close to that for any of my tasks. I would have been out of memory a long time ago if I did.

Your heap printout doesn't appear to be that close to running out. But having multiple tasks with 12K and this one at 25K does seem suspect. Plus, look at the min stack on your task is still at 23K when calling the routine you run out. Try making it 6K instead of 25K.

To test I've cloned the ESP32_curl_example repository into new directory.
Run:

Code: Select all

make menuconfig
make -j8 all
make flush
make monitor

I've only changed WiFi and mail data in menuconfig.
Main task stack size is 3584 B (default).

There was no problem and all examples passed without any issue:

Code: Select all
