Notice of upcoming change: ESP-IDF will assume 40MHz XTAL frequency by default

Currently during ESP-IDF startup we estimate the XTAL frequency, by measuring the number of XTAL clock cycles within certain number of internal 8MHz oscillator clock cycles. This method has proven to be not fully reliable, due to variation of oscillator frequency between individual chips, and temper...

Notice of upcoming change: ESP-IDF will disable ROM BASIC console

We are planning to roll out a change which automatically disables ROM BASIC console by burning respective Efuse, when the application starts up. Newly produced ESP32 chips will also come with ROM BASIC console disabled. If you wish to preserve this function for your chips/modules, please use `espefu...

Re: JTAG debuggers

Couple of questions: Which example are you running on the ESP32 when the issue happens? Which commit id of openocd-esp32 do you use?

Re: Small ESP32 Modul ( all include in new ESP32-PICO )

That looks like the same arrangement of pins as in D2WD, is it not?

ESP32-D2WD’s pins GPIO16,GPIO17,SD_CMD,SD_CLK,SD_DATA_0 and SD_DATA_1 are used for connecting the embedded flash, and are not recommended for other uses.

Can you give us some indication what kind of application you are aiming at? Do you need symmetrical cores or specialized ones / accelerators?

Re: My ESP-32 EVK with sd card,codec and eth

Thanks!
One note on the schematic — you may consider adding a capacitor on the EN line, see 3.1.2.2 in "ESP32 Hardware design guidelines".

(later)
It may also be nice to have all the connectors for cables (USB, Eth, audio) roughly on one side of the board.

Re: My ESP-32 EVK with sd card,codec and eth

Can you post the board schematic on the Wiki or on Github?
