I'm using ESP32 Thing from sparkfun. He said that it should be fixed in v1 silicon That sounds like my problem. When I source these parts, how do I make sure I get v1?

What's the specific part? Most likely we are having an issue switching clock to PLL. Curious thing however is that i can't reproduce this on the test board I have here. Will try a few other boards on Monday. Jump to. Who is online Users browsing this forum: Google [Bot] and 52 guests. All times are UTC Top.

Skip to content. Reset functionality on ESP32 covers a lot of different subjects. The technical reference manual Section 3 Reset and Clock covers types of reset. The ESP32 datasheet covers strapping pins which are used to determine the boot mode at reset. I wanted to know that, there is no any separate pin for reset. So is it possible to connect switch externally to any GPIO to reset it or it is not necessary because it is being done internally through coding I am making schematic for my project so.

I am making the schematic for my project using Wroom module. Jump to.

The problem manifested as an ACK error. In addition to this required bug fix I propose:. Hi stickbreakerI pulled your changes to my local environment, but I'm getting random reboots. I'm using a display library which throws the following errors:.

Honestly I'm not sure if your changes cause it, but I never had this before using your code from this PR. Edit: I reverted the changes and don't see the error coming up. Another point is that I dont have the display connected to the board which might be a bad idea. Will you make two debug changes and rerun this? I've got a SSD thanks cyberman54 so I might be able to use your failing code. If you want to send it.

One line of Wire. I've pulled this PR and integrate to my environment, so far not found any issues. I'll keep testing. Error 5 is an Arbitration error:. The last interrupt in the dumpInts is 0x with is the arbitration failure interrupt. This error could also be created if the pullups on the i2c bus are weak. The errorByte and errorQueue values tells that the First byte of the requestFrom is where it failed.

Hi stickbreaker. Loaded up the latest esp32 ardunio core yesterday and my MPU invensense library is failing to read the device. I found this thread and I can see the changes you have done. Many thanks! Looking through the driver code for wire. What's the best way with the proposed changes here Chuck? The comment is kind of questionable, I don't know about the use of 'connection' in i2c parlance.

Try this simple change, It's quick, and may work. PR solved a interrupt saturation problem. This new PR seem to function correctly, I have ran it through more testing.

So, no data is stored into the Read buffer. The code you published does not check the return status of endTransmission so it never sees the different return code. If your code was:. After that, I2C reads broke again! It was the comment from stickbreaker : You can try changing the sampling code to not have ReSTART, It may not actually be necessary for the proper operation of the sensor.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I was reading the ESP. But is there a final solution or is the, manually reset after serial flashing, the latest work around? Its dam hard to search for. For some reasonthis only happens with larger programs, if you just upload a program with the system restart command in and that is it, it works fine After flashing all AT commands worck good.

I suggest asking at a community forum like esp See in this comment. If a GPIO pin is set high or low prior to restart, will it remain in that state after the restart? I want to remember that state when the program reboots, if that makes any sense.

Skip to content. Practically the simplified script shown below, uses a Nextion LCD display that connects via the Hardware interface 2. In a more elaborate script I am using the ESP.

The simplified script below writes and reads 5 times back the data stored by the Nextion MCU. The result shows that everything is fine until the "software restart" occurs, only a physical restart or firmware reloads solves the problem!!!!! Code: Select all include "Nextion. So as I understand the patch described above was a workaround for me, but not an actual solution. Last week I have decided to verify if this problem was not solved by the latest version of the espressif-arduino library and as a matter of fact it is.

So please try the last version to verify if this solves your problem too. Now there is a undocumented feature; you don't may not specify Code: Select all HardwareSerial Serial2 2. Code: Select all include HardwareSerial. Code: Select all Serial2. New version is 1. So I upgraded, and I see news is that Serial2 does not need to be created, it is already created by Arduino framework.

But bug is still there, Serial2 works for me when plugged to power supply. After ESP. Using my ESP32Serial implementation it still works. So, I am not sure you are doing same as me or we are using different version of espressif-arduino.

Anyone else still have issue described here? BR, Tihomir. So if it was not working for you before, it should not work now. Jump to.

I am having almost the same problem, so didn't open new issue and wrote my issue over here.

Please have a look into it and let me know what can be done to solve the issue. The system rebooting continuously by providing following output at serial port when the serial monitor is opened.

I did try it with external power supply 3. If not, that is why you are still seeing brownout errors. The esp32 requires a lot of current when the WiFi system initializes. Is that a sustained mA? It is possible the esp32 is attempting to pull more current, do you have a way to test the current load by the esp32? New esp32 board?

To confirm it is or is not issue with board next step should be to use new board. If its not esp32 board then it is either usb cable or power supply, there is no other option for brownout or you are very unlucky and have 2 esp32 boards broken. I am not sure if it's broken, because it can run other codes which do not need wifi. For now, I haven't introduced any other peripheral. S this isn't a ready-made development board kit, I have made it from the breakout board and placed the ESPWroom chip on it.

If it only fails when wifi is enabled then it is a power supply issue. The WiFi system does require a lot of current when starting up, the datasheet specifies at least mA for the power supply.

Very likely if you provide closer to 1A it will work fine. But even using this, the output still shows a brownout error. I think I will have to use another breakout board to test the esp The brownout message is gone but instead guru Meditation error is shown:.

I try a wifi connect in this case, if this doesn't help I intended to restart my ESP32, see loop below. My console log shows exactly one line Restart after XXX but the system did not restart. Is it possible that ESP. In some demo sketches I saw a delay xxx after the ESP. I didn't saw any reason for this and didn't include it. Am I missing something? I think you are not doing your xtasks properly and are getting endless loops that the watchdog kills.

The other threads are still looping as expected afterwards, as I can see by their debug output. What if my assumption is correct? Would ESP. There is no ESP. I think it is just an alias for restart. I use the watchdog timer to do a hard restart like this:. Is my understanding of this example correct: you initialize watchdog timer to call the panic handler which reboots the ESPif the timer does not get a reset every second and than you start a CPU consuming loop that will trigger the timer quickly.
