May i disable coredump writing to flash, during the runtime?

Hello. Im check dump partition during startup and write it on SD if it found. But there is a case, when ESP crashes in seconds after boot. It leads to heavy flash wearing. So im have non-volatile module, what ensures what coredumps saves to file only if specific time runs out. It save SD from wearin...

Solved. To delete

Im trying the next code.

Code: Select all

	static uint8_t i = 0;
	volatile uint8_t j = 0;
	if(!i) {
		j++;
		i = 1;
	}
	esp_restart();
Breakpoint on "j" hit once, and never more.
What im doing wrong?

Does redirected printf-like function called in same task as well as its ESP_LOGx ?

Hello, the question is in title.
If yes, does it means, what some task may wait before other's task PRINT function ends work and give back semaphore?
Or PRINT function must be reentrant?

Re: Using ESP-PROGs second channel as UART with enabled JTAG

Ok the problem was what Interface 1 drivers was not "True" FTDI drivers, but Zadig's USB-CDC, they successfuly work as serial port, but someway's conflicting with WinUSB in interface 0.

After installing FTDI's drivers on interface 1 the problem is gone.

It must use interface 0, but when i try to begin debug - it fails, says what interface 0 has no WinUSB drivers (but it has, interface 1 has not). interfac...

Hello. Im trying to use FTDI's B channel as UART simultaneously with JTAG on channel A. On schematic I see no obstacles. But if im install default drivers on B interface, JTAG stops to work with "libusb_claim_interface() failed with LIBUSB_ERROR_NOT_SUPPORTED" Can i workaround this? Or in JTAG mode ...
