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?

Re: ESP32 as a SWD debugger (and maybe JTAG)

Hi Paul, (This is not official Espressif advice, but I've messed around with debug protocols a bit and I think this is a cool idea, so I can give you some tips.) If possible, try to obtain a copy of the "ARM Debug Interface Architecture Specification" document. It used to be downloadable f...

Re: Electronic components tips for my circuit

If you measure the voltage at the ESP32 pin with a multimeter (measure between IO4 and GND), do you see it swap between 0V and 3.3V when you press the button?

Re: Need info about Dual Core Bug 3.10

Hi Jaime, The short answer is: for nearly all users of the ESP32 there is no impact from this bug. It's taken care of in software in IDF V3.0 (currently this the IDF master branch, the V3.0 release is coming soon) when using IDF code & drivers. If you write code which reads peripheral registers ...

Re: "strptime" don't get compiled

Hi Gfast2,

Thanks for reporting this. This is a bug in IDF. The file is compiling correctly but linking is failing because strptime() is missing from the libc library. We are working on a fix.
