Error: JTAG scan chain interrogation failed: all zeroes Error: Check JTAG interface, timings, target power, etc. Check your hardware, there's probably something wrong there. Also, make sure that whatever code is running on your ESP32 doesn't reconfigure the JTAG pins for other use. Hi ESP_Sprite, T...

Hi all, I'm trying to debug my ESP32 through JTAG interface .My debug module which is used is FT2232HL. After following all the steps that are mentioned thoroughly on this link: https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/jtag-debugging/index.html#jtag-debugging-building-openocd...

Hi Wifive,
How about normal Mode .
How does RTC work in Normal mode.
And as i 'm setting my time with mktime i'm realising that my rtc time starts getting deviated after a while.

Thanks,

This file has a lot of information in the help sections of the menuconfig options about rtc and timekeeping which you can also view when in menuconfig https://github.com/espressif/esp-idf/blob/ad3b820e701c3ef0803b045b5a2c5ef19630fb0b/components/esp32/Kconfig Hi wifive, I' afraid that i still cant g...

Hi all, As i can figure out from make menuconfig that tick rate of ESP is 10 ms .How ever are there any internal RTC api's that give me the tick rate of RTC as i understand that RTC is working on different clock then ESP does. Also, what does "Number of cycles for RTC_SLOW_CLK" Calibration signify? ...

It does seem to be possible. Try this: (it's also used in there to calculate hashes of the current program, which is a good example usage) https://github.com/espressif/arduino-esp32/blob/e602145c2b822a6d9288ae31c0d9ca8a7ee097d1/cores/esp32/Esp.cpp#L151 Looks like the real magic happens here, for in...

Ah, so you want to figure out the size of you firmware at runtime? It may be possible, but I'm not sure what the use case of that would be since you know it at compile time... You can read out the contents of a partition (though the factory partition may be protected in some way so you can't corrup...

Hi eagi,
Thanks for the response. However are there any api's that do the same?

Hi everyone,
is there any API to know the size of my firmware size .Matter of fact is there any api to know the amount of portion written in a given partition.
