Re: WDT timeout in bootloader for ESP32s2

Hi Angus. Some answers.

Yes the apps is definitely running for 1.2 seconds. There is app log showing.

Yes, the log output indicates that it is past the bootloader and into the app. I assumed it had to be to do with the bootloader because the address given only appears to be valid for the bootloader, not the app.

addr2line for the app gives:

Code: Select all

E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x4004c3ee
0x4004c3ee: ?? ??:0
After printing "boot.esp32s2: WDT reset info: PRO CPU PC=0x4004c3ee" it starts the app, runs for about 1.2s and then resets. Extended log here:

Re: WDT timeout in bootloader for ESP32s2

Postby william.ferguson.au » Fri Jan 08, 2021 4:19 am

Hi Angus. Some answers.

Yes the apps is definitely running for 1.2 seconds. There is app log showing.

Yes, the log output indicates that it is past the bootloader and into the app. I assumed it had to be to do with the bootloader because the address given only appears to be valid for the bootloader, not the app.

addr2line for the app gives:

Code: Select all

E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x4004c3ee
0x4004c3ee: ?? ??:0
After printing "boot.esp32s2: WDT reset info: PRO CPU PC=0x4004c3ee" it starts the app, runs for about 1.2s and then resets. Extended log here:

Re: WDT timeout in bootloader for ESP32s2

Postby william.ferguson.au » Fri Jan 08, 2021 4:24 am

To put this in context.

This code works

Code: Select all

    // All My setup code  is above here.

    ESP_LOGI(TAG, "Finished setup");

    // NB this line was added just to stop the app from aborting during startup. It is a hack.
    // See https://www.esp32.com/viewtopic.php?f=2&t=18842
    ESP_LOGI(TAG, "Finished setup2"); //

    while (true) {
        vTaskDelay(LOOP_DELAY_MILLIS / portTICK_PERIOD_MS);
    }
This code causes it to abort as per the logs above. And it aborts before never gets anywhere near the 2 lines of logs shown.

Code: Select all

    // All My setup code  is above here.

    ESP_LOGI(TAG, "Finished setup");

    // NB this line was added just to stop the app from aborting during startup. It is a hack.

Re: WDT timeout in bootloader for ESP32s2

@ESP_Angus we realise this might be intractable without the source code.
How can we share that with you privately?

Re: WDT timeout in bootloader for ESP32s2

Hi william,

In the standard ESP-IDF config, TG1WDT_SYS_RST is from the "INT WDT timer". Normally an interrupt WDT will trigger an interrupt first to run the panic handler, but if the interrupt can't be handled (for example if it's triggered while running in a high priority ISR with interrupts masked) then the hardware WDT will step through to forcing a reset.

(The WDT mentioned in the bootloader config is the RTC WDT, which has a different associated reset cause.)

It's possible there is some code in the app which is disabling interrupts (or running in an ISR) for a period of time very close to the configured INT WDT timer period. Because changes in binary layout can cause changes in the flash cache access pattern and therefore small changes in the timing of the app, it's possible that one particular .bin file layout is marginally slower than the others and is causing the time with exceptions disabled to nudge over the WDT threshold.

It seems like there may be also be an ESP-IDF bug that in the case of TG1WDT_SYS_RST, the "watchdog" address printed by the bootloader is wrong. Will check this.

If you look up the "Saved PC" address printed by the ROM earlier in the boot, do you get anything meaningful? In the log it seems like there are a few slightly different addresses being logged, so this may help give you some clue of where the CPU is running when it triggers.

If it is a long-running ISR that's triggering the INT WDT then the solution may be as simple as increasing the INT WDT timeout in menuconfig, if you're happy for interrupts to be held up for that period of time.

If you try the things mentioned above and still are not able to progress, then I'll PM you a way to share the source.

Angus, none of those Saved PC addresses look valid:

Code: Select all

E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x40334a6f
0x40334a6f: ?? ??:0

E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x40334a71
0x40334a71: ?? ??:0

E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x40334a6d
0x40334a6d: ?? ??:0
We only have 3 interrupts. All short lived:

Code: Select all

static void IRAM_ATTR bananaplug_isr_handler(void*) {
    // Check for and set a circuitClosed here and then notify main loop to handle it.
    if (!circuit_closed) {
        circuit_closed = true;
        uint64_t received_at_millis = millis();
        xQueueSendFromISR(bananaplug_evt_queue, &received_at_millis, NULL);
    }
}

void IRAM_ATTR beamatouch_power_isr_handler(void*) {
    xQueueSendFromISR(power_evt_queue, nullptr, NULL);
}

static void IRAM_ATTR button_isr_handler(void*) {
    uint32_t ignored = 0;
    xQueueSendFromISR(button_evt_queue, &ignored, NULL);
}

OK, much thanks to Angus for help on this one.

Turns out it was a conflict between flash and PSRAM brought on by our erroneous use of GPIO26 on the ESP32S2 Wrover.

Turns out it was a conflict between flash and PSRAM brought on by our erroneous use of GPIO26 on the ESP32S2 Wrover.

What exactly does "erroneous use" mean?

It seems that I have a similar problem with EPS32S2 Wrover.

Code: Select all

I (24) boot: ESP-IDF v4.4-dev-1254-g639e7ad49 2nd stage bootloader
I (24) boot: compile time 10:55:01
I (24) boot: chip revision: 0
I (28) boot.esp32s2: SPI Speed      : 80MHz
I (32) boot.esp32s2: SPI Mode       : DIO
I (37) boot.esp32s2: SPI Flash Size : 2MB
W (42) boot.esp32s2: PRO CPU has been reset by WDT.
W (47) boot.esp32s2: WDT reset info: PRO CPU PC=0x4004c3f6
The crash (timeout) occurs after calling the function:

Code: Select all

i2c_master_cmd_begin(i2c_num, cmd, 1000 / portTICK_RATE_MS);
I2C SDA pin is assigned to GPIO26.
