Hi Rahul, Glad to hear that you and Ritesh are making progress. esptool.py v2.0-beta1 This version of esptool.py is very old and predates support for efuse pin remappings. You will probably need to use IDF v2.1 or more recent, as these are the versions which added support for ESP32-D2WD (which also ...

This comes up quite regularly, so I've added a wiki page on the esptool.py wiki:

Does anyone has any idea or suggestions to connect and configure second 16 MB SPI flash memory along with 4 MB SPI Flash memory which is attached into ESP32-WROVER-I module? Hi Ritesh, Please continue this discussion in the separate thread you already created for this purpose: https://esp32.com/vie...

Also, I just want to add extra 16 MB external SPI Flash memory in addition to 4 MB SPI Flash memory. So, would you please suggest pin configuration for that and is it possible or not? Mainly my purpose is to add some more extra memory interface in addition to existing one for my application develop...

But In begin is recevied a lot of noise, I think that codes of SDK is still in 115200 until execute main The ROM bootloader code will always output at 115200, before it loads the second stage bootloader image from flash. From then on, serial output will use the configured baud rate. Unfortunately w...

I think you should also credit amuzyka-grinn who was the first one to implement the PPPoS support.

Oops, I should indeed. Mis-remembered!

PPP over serial support is marked as unsupported in V2.1 and in the current master branch V3.0-dev versions. The reason for marking it as unsupported is as follows: It was community developed and contributed (thanks loboris). We thought it was so useful (and it requires modifications to the IDF core...

However 40K is a large amount of memory, it would be better if there is a way to turn the "memory pools" to low size. I think Kolban made up 40K in this case to illustrate the point. How much RAM are you seeing being used? There are some configurating tuning options for both WiFi and LWIP (under th...

Those sockets will be close and resocket frequently. a few time after the esp32 starts to run, I notice the memory gots smaller and smaller using esp_get_free_heap_size To expand on kolban's answer, closed TCP sockets will appear to "leak" some memory because of the TIME_WAIT state. If you wait ove...

We have a bug that looks a lot like this that we're currently working on a fix for. In the meantime if you disable core dump in menuconfig then you'll be able to avoid it (or you can run make erase_flash to clear the core dump partition.)

Will let you know once we have a fix.
