Re: Look out,I found so many problems with the d2wd!

I'm sorry that you assumed the D2WD is exactly the same as the D0WD; because the flash is connected to different internal I/O pads, that is just not true, and hence needs an up-to-date ESP-IDF. Also, my apologies for the fact that the flash tool was not updated; most developers use the internal espt...

Re: Audio Output

Yes, there is, unfortunately because of reasons it will take a while. I'm not too up-to-date with Arduino, but from what I know there's no I2S interface there yet. You may want to see if you can use the ESP-IDF driver from Arduino: docs are here http://esp-idf.readthedocs.io/en/latest/api-reference/...

Re: Is brownout detection usable now?

FWIW, the issue with the ESP32 is usually 'weirdness' (often an illegal instruction exception) on WiFi bootup; unrelated to the TCP/IP stack or the drivers itself. It's separate from the ESP8266 issue.

Re: Guru Meditation Error of type IllegalInstruction?

What hardware do you use? Weirdness on WiFi startup is 99% of the time caused by your 3.3V rail not being able to deliver enough current.

Re: Audio Output

You can use the I2S driver from esp-idf; that makes the I2S peripheral handle all the timing and allows you to just push (blocks of) audio samples into it which then come out of the DAC or an attached I2S codec. Pretty sure the ESP32 can do what you want pretty easily, by the way: with an ESP32 at 1...

Re: Successful connection of Segger J-Link for JTAG use

If you change that line to '[find tcl/interface/jlink.cfg]', it should work.

Re: Successful connection of Segger J-Link for JTAG User

Edit the copied esp32.cfg file. Most importantly, change the source [find interface/ftdi/tumpa.cfg] line to reflect the physical JTAG adapter connected. (Note that this step is not needed when using the ESP-WROVER-KIT


What did you do at this step?

Re: why the d2wd always reset auto for nothing?

If anything, 250mA is on the low side... to be sure, you probably want to have a PSU that can deliver 500mA@3.3V, at least for short peaks (WiFi calibration, for example). If any, you may want to just feed the chip 3.3V directly from a lab supply using thick and short wires to see if this is the iss...
