Ah, one other very likely thing I didn't spot the first time: uart_isr_register(UART_NUM_2, uart2_isr, NULL, ESP_INTR_FLAG_IRAM, &uart2_intr_handle); Are you sure that all of the code that can possibly be called from uart2_isr is in IRAM? If not, problems can occur while writing to flash and this c...

It is the RTC watchdog causing this problem. Possible solutions: Disable RTC watchdog: Bootloader config->Use RTC watchdog in start code Increase RTC timeout Bootloader config->Timeout for RTC watchdog Feed RTC watchdog: import "soc/rtc_wdt.h" and invoke "rtc_wdt_feed();" periodically Check this thr...

I am facing similar issue when migrated from v4.0.1 to v4.2 The device reboots almost every 10sec Attaching a very basic code with sdkconfig from original project. So, I am guessing, it's something in sdkconfig Here is the log ets Jun 8 2016 00:22:57 rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_F...

I have a similar problem. Getting following error. [0;31mE (298214) esp_image: Image hash failed - image is corrupt[0m [0;31mE (298784) esp_image: Checksum failed.

Hi @xiaoxufeng I ran the command but I guess I am doing something wrong Following is the output esptool.py v2.8 Found 1 serial ports Serial port COM3 Connecting........_____. Detecting chip type...

Additional update:
Tried same thing by updating to idf v3.3.2 as well as v4.0.1
Same issues. I can provide additional logs if required.
Basically, I would like to update to either v3.3.2 or v4.0.1 as they contain MQTT module with lot of bug fixes.

Currently I am working with ESP32 S node mcu dev board. You may test with the same

## Environment - Development Kit: [none, custom product using wrover module.] - Module or chip used: [ESP32-WROVER 32Mbit] - Operating System: [Windows] - Power Supply: [on-board 3.3V] - IDF version: v3.1 Application uses custom partition table as follows # additional nvs data otadata, data, ota, 0x...

I am facing the same issue with I2C example provided in idf. ESP32 Arduino works as expected whereas esp-idf gives the following errors timeout : 0x107 (generated by I2C_STATUS_TIMEOUT) failed: -1 (generated by I2C_STATUS_ACK_ERROR) The slave is an Arduino device. ESP-idf version: v3.1 Code: #includ...

Looking at your code a bit better, I think you're not using the driver correctly... you're supposed to either use uart_driver_install() so you can use all the nice queued read functions etc, or use uart_isr_register() to install your own ISR and handle all hardware things yourself. In your particul...
