wonnachai2 commented 5 years ago

@stickbreaker I guess that this is a 2019 Version of ESP-32 (Newest) but board esp-32 in Arduino IDE is older. I think right or wrong?

lbernstone commented 5 years ago

See #3036 Unless you work for Espressif, your board is supported in Arduino IDE :smile:

wonnachai2 commented 5 years ago

@lbernstone Where is the Local of esp32/tools folder. I don't found it.

lbernstone commented 5 years ago

Since you did not follow the issue template, I do not know what operating system you are running. Modern OSes have the ability to search for a file.

thylive commented 5 years ago

have you solve the problem?

wonnachai2 commented 5 years ago

@thylive No , I can't solve it.

atanisoft commented 5 years ago

@wonnachai2 We can't help you solve this without you following the issue template. You also need to be VERY explicit in which esp32 module you are using, there is no module named "esp32 2019 version". What exact one did you purchase on aliexpress? What do you have connected to the esp32 module?

There are more questions but until you answer the above and follow the issue template we can not help you resolve your issue.

@thylive If you have a similar issue I'd suggest not hijacking this one and create your own for tracking and please follow the issue template so we can help you with your issue.

Also note that a lot of us are available here to assist.

Try by changing the flash mode from QIO to DIO

wonnachai2 commented 5 years ago

I try all lof method but it still same poblem , Now I buy new ESP 32 but I get a same poblem. (I notice that may old ESP32(can use) have a blue point on board) but my all of new esp 32(can not use) have a yellow point on board . @thylive Does your borad have a yellow point on board ?

I do’t think it‘s yellow point‘s matter,if you use esptools to chick this chips , you will find that the cpu is 160mhz , but others are 240 mhz.

check you chip , is there 2019 on it? i think this is 2019 version .

I don’t know why but the aliexpress boards with esp32 they have lot of problems, First, I was able to run only with the DIO flash mode, 2nd they have lot of problem of soldering.. sometimes I need to resolver better the module pads

You get what you pay for often... There are a number of sellers on AliExpress and not all are equal when it comes to quality control.

So far in this issue there has not yet been one definitive reference to the "bad board" just a bunch of vague references to a board that doesn't fit with any of the known boards. It is very likely this is a poorly manufactured clone of another board but without seeing exactly what board it will be very difficult to suggest a proper answer to the original issue being reported.

ESP32 mini S2 had this problem (still has on some boards from ebay/amazon). The issue was restarting evey 1 second or so when using WiFi (broadcast a wifi network).

Solution from other forums: One capacitor on boards is not soldered right to GND. Some newer boards are working fine. See below. I tried to solder a blob of solder a 1/4 inch wire to EN pin on board (also tried 1 inch coiled wire), and it helped, esp32 is not resetting itself anymore and works fine.

Bad module was from amazon, good from Aliexpress (12.2023 order).
