Hi all! I've been trying to dive deep into the ESP32 internals, but can't quite find all the information I'm looking for. I'm trying to understand the process that configures the SPI flash for usage. Here are the couple points that I'm stuck on. I know that the ESP32 uses external flash for storing ...

Hi Casey, Thanks for the detailed bug report. I was able to reproduce and have committed a fix for review internally. (You were on the right track: there is a static function is_created_by_socket() in api_lib.c which checks if a netconn has a controlling socket. If it does, netconn_free() is deferr...

Fantastic, thanks Angus! Happy to help.

Hello! So, I've been doing some work on TCP sockets with the ESP32, and it appears I have run into a memory leak that only appears if the socket failed to open. I have attached code for a sample program that reproduces the bug. In menuconfig, set the correct WiFi credentials for your network under "...

I have not, I'm not at a point where I can buy large volumes, which I assume I'd need to in order to get it direct.

And max size 128 KB + max clock 20 MHz, quite unusable as ESP32 external RAM. Yes, but even more unusable is the lack of the ESP-PSRAM chip from distributors...I would much rather use a different, 128KB chip than nothing. Is the 20MHz a deal-breaker? Looks like the ESP32 runs external RAM at 40MHz ...

Hi all, I love the fact that the ESP32 supports SPI RAM. I understand that there are limitations to putting a lot of RAM on-die, so I appreciate the option of being able to implement external RAM. However, I was surprised to see that the only chip that's supported is the PSRAM chip manufactured by E...

Hi there, I am trying to use the memmem function from newlib, but I'm getting "error: implicit declaration of function 'memmem'", despite including "string.h". I can see code for memmem in the newlib code for the esp32...is it for some reason not included in the IDF? I imagine there is some silly re...

Goood point. Cheers Angus.

I just updated to the latest IDF incl. submodules and am now running with comprehensive mode. No longer crashed on startup so that's a good sign. Will leave it overnight and report back. - memcpy(new_p, ptr, old_size); + memcpy(new_p, ptr, MIN(size, old_size)); Whew...that seems like a major buffer...
