Re: ESP32 Ethernet kit V1.1

Can you share the latest hw-reference with me? Joop Hi Joop, Documentation for ESP32-Ethernet-Kit V1.1 should be released soon. In the meantime please refer to https://dl.espressif.com/dl/schematics/SCH_ESP32-ETHERNET-KIT_A_V1.1_20190711.pdf. The PoE board is the same as in ESP32-Ethernet-Kit V1.0 ...

Re: ESP32 - JTAG Non-Functional w/ Stock Firmware

1. Can the existing OpenOCD scripts be modified to some how latch the JTAG interface before the user application disables it? I'm looking how to avoid this issue in manufacturing without switching to the UART interface. I'm also concerned with users potentially locking themselves out of the product...

Re: Another ULP timer question

The ULP WAIT instruction appears to have no effect when the system is in deep sleep. Hi wevets, When the system is in deep sleep ULP is halted (ULP program is stopped), so the ULP WAIT instruction has no effect. Please also see diagram on page 614 of the latest ESP32 Technical Reference Manual V4.0.

Re: ESP32-WROOM-32D Minimum Voltage

Hi Mattia,

This is related to current drawn by SPI flash on board of ESP32-WROOM-32D and voltage drop on internal series resistance. For description please see PCN-02-20190815, point 1 under "Reason for Change" as well as "Impact of Change", points 1 and 2.

Re: Can't get UART2 work with default pins 16 & 17

Hi Lio590,

What exact ESP32 module type do you have on your board?

Please check a note about GPIO16 and 17 for ESP32-DevKitC V4 (I guess this is the board you may refer to) at the end of Functional Description section, if it is applicable in your case.

Re: Documentation Requests/Feedback

Hi @Mr_Red, You are right, for “stable” release the specific version number is not immediately visible. It may be checked by clicking Get Started . Answering you other question, "release-v3.1" shows the current state (latest commits) of the release/v3.1 branch. To summarize on documentation availabl...

Re: BOOT: to press or not to press.

Hi stamasd, I see you are using V1 version of ESP32-DevKitC. This is fairly old version and I believe related description and fix specific for Windows is covered in https://github.com/espressif/esptool/issues/136. Try adding a capacitor as discussed in this issue report and the issue will likely be ...

Re: ESP32 PICO KIT 4.1 - MTDI Pullup

Hi RobStev0,

NC besides an element on schematic (e.g. R23) means that this element is "not connected".
