The device works after reflash application firmware.
But I'm wondering if this device is OK or something is already damaged?
Does "csum err" mean part of the hw is damaged?

Hi, Test on esp32c3 v5.1-dev-2186-g454aeb3a48. I sometimes hit below issue when wakeup from lightsleep. (wakeup by gpio). What does this log mean? (any hint for debugging this issue?) 3fc957c0: 0x00000001 0x00000001 0x00000000 0x0001ffff 0x00000000 0x00000000 0x00000004 0xb33fffff 3fc957e0: 0x000000...

Hi One of my esp32-wroom-32E device hit below issue. Can someone help to tell what was wrong? (The device was working yesterday, not sure what's wrong. it keep rebooting now). rst:0x10 (RTCWDT_RTC_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_...

In Power-down of RTC Peripherals and Memories section, it says esp_sleep_pd_config() function is provided. https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/system/sleep_modes.html#power-down-of-rtc-peripherals-and-memories But calling esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_...

Also, I often get "wifi:<ba-add>idx:1 (ifx:0, aa:bb:cc:dd:ee:ff), tid:5, ssn:1, winSize:64" and similar warnings. Do I need to worry? Some documentation would be useful! https://espressif-docs.readthedocs-hosted.com/projects/espressif-esp-faq/en/latest/software-framework/wifi.html#after-being-conne...

A. I find it hard to believe it drifts over 20 minutes in 12 hours.
B. How do I make it work to be at least within a few minutes max?

Setting CONFIG_RTC_CLK_SRC_INT_8MD256=y can improve this.
But there is another wakeup time bug as I mentioned above.

You may also be able to work around it in software: for instance, set your wake time 40 minutes earlier than when you want to wake up, then during that 'early wakeup' get the current time (e.g. from ntp) and set deep sleep for the small period to the actual wake-up. That trick should get you an acc...

FYI, you probable want to wait for this bug fix:

There are some bug in esp-idf regarding wakeup time, e.g. https://github.com/espressif/esp-idf/issues/9455

The C3 has an USB device that effectively replaces an external USB-serial and USB-jtag chip; you should be able to use that to flash updates.
