Re: MSYS Issues - cygheap base mismatch detected

Usually closing and reopening the terminal should resolve this, and you should only see it after upgrades.

If you follow the advice in the error and search your system for cygwin1.dll, does it find any other copies anywhere?

Re: [mbedTLS] leak on mbedtls_net_connect [spoiler lwip_getaddrinfo]

Hi FP, I'm not entirely sure what you're seeing here. The attached code seems like it shouldn't leak memory, at least at a glance. There is one thing in ESP-IDF which can look like a memory leak, which is that TCP sockets have to stay in the TIME_WAIT state for a period of time after the connection ...

Go for it, cmorgan. Absolutely no problem, as long as it's ESP32 related. :)

Re: What files are required for flashin

Are you using ESP-IDF? If so then the output from a successful build ("make") includes the command line to flash the device with esptool.py. You can send them this command line along with all of the .bin files mentioned there.

Re: bootloader doesnt respond (manually bootloading)

Hi jbeemster, It's hard to guess without knowing the details of the board you have, but is it possible the TX signal from the PC is not getting through to the ESP32? In this case you'll be able to read the boot message (as you have), but esptool.py will fail to make contact. If there's another onboa...

Re: "strptime" don't get compiled

Glad you found a workaround. On the current IDF master branch (as of 7e8c2a9), strptime() will link correctly.

Try adding more calls to heap_caps_check_integrity() at different times in your code, and narrow down a window of time when the corruption occurs. Then look for code in that window which is overflowing a buffer or writing to memory which it shouldn't be writing to.

Re: Undefined reference to `xPortGetFreeHeapSizeCaps(unsigned int)

Can you please post the full output of "make V=1"?

Please copy it onto a site like https://pastebin.com or https://gist.github.com and then post a link to the forum.

Re: Undefined reference to `xPortGetFreeHeapSizeCaps(unsigned int)

If your source is really .c and not .cpp then try removing the extern "C" block from around the #include.

Do you get any other warnings or errors from the compiler before that one?
