This is a simple example to test my master-slave modus device https://github.com/espressif/esp-idf/tree/master/examples/protocols/modbus/serial/mb_master https://github.com/espressif/esp-idf/tree/master/examples/protocols/modbus/serial/mb_slave same connection and code as per example still I am get...

Just give it a try hope it will help you... #define msdelay(tick_t) (vTaskDelay(tick_t / portTICK_PERIOD_MS)) xTaskHandle vip_task_t; BaseType_t isvip_task ; void vip_task(void * arg) { // no forever loop // do work 0.1 seconds msdelay(1); isvip_task = pdFAIL; vTaskDelete( vip_task_t ); vTaskDelete...

Its already done,
1)Mapping external PSRAM including the setting of malloc/calloc option
2)Mapping .bss memory segmet to external RAM

Yes, I got that already, still thank you for highlighting and replying. please follow below points I have summed up so far. 1) so when I increase the stack size as required for the task, memory allocation to task fails even though I can see I have 4MB memory available. 2) If I allocate some of all t...

ESP32 wrover-b(8mb flash 8mb psram) Ported code from esp-idf v3.3.3 to v4.3 stable For FFT using esp-dsp lib Following are the errors I am facing 1) ***ERROR*** A stack overflow in task procc_data has been detected. 2) Task creation failed due to memory allocation failure, but I (13860) Start memor...

Hi everyone, I am using esp-idf v3.3. Esp32 clock frequency set to 240 MZ I am facing the same issue, the following is my code flow and code. It's a very simple code. Code flow 1) send command 2) wait till all data received in rx_buff of UART driver 3) Once all data received in rx_buff read that dat...

I am using esp-idf v3.3. Esp32 clock frequency set to 240 MZ In my code I have a serial task with priority 21 and stacksize of (1024*12) pinned on core zero, to read serial data from UART_NUM_1 using Pattern detect. I receive approx 50 kb data in rx_buff in just 2 Sec in UART_NUM_1, as esp32 receive...
