Re: CAN frame corruption following FATFS write to FLASH

Some things that would be useful to check/known: What CAN frames were being sent to the ESP32? What data did they have? Were they STD or EXTD ID? Could you check the flags of each received message? Currently, the driver doesn't handle RX FIFO overruns. The following modification to can_intr_handler_...

Re: station_example_main.c: xEventGroupWaitBits missing?

Seems like you're correct. There should be an xEventGroupWaitBits() call at the end of app_main(). I'll open a ticket to fix this issue.

Re: Build idf.py build issue

There are a bunch of example projects in esp-idf/examples. I suggest you chose one of the projects in get-started.

Re: ESP32如何触发软件复位?

有几种方法
  • 内核复位:除了RTC,会把整个digital 的寄存器全部复位,包括CPU、所有外设和数字GPIO。可以用RTC_CNTL_OPTIONS0_REG 的 RTC_CNTL_SW_SYS_RST 引发

Re: Can anybody explain me some things about the ESP32?

I have to transmit pulses created by an ATmega128 (my plan is to wire ATmegas' UART1 RX/TX with ESPs UART0 RX/TX) but I'm not sure how to set the UART0 only to recieve Not sure if that's a good idea. UART0 is the default UART for all of the ESP32's log output. Therefore, by setting UART0 to receive...

It shouldn't need to be activated. Which development board are you using? And is it a CP2102 or a CP2102N?
