Re: Unstable partition API flashing functions

I''ve updated to the latest Master branch of the IDF (as of yesterday v2.0-rc1-666-g0fe765a9) . The function to calculate the Md5 hash using memory map of the SPI flash is now hanging and causing WDT reset. Can you post the snippet of code that displays this problem? If you comment this calculation...

Fully-fledged or fleshed out maybe. Or is it an Aussie thing?


Oops, yes I meant fleshed out. I blame early morning lack of coffee. :)

Re: Secure boot problem

Sorry for the delay in replying.

This has been fixed in esp-idf master branch as of commit 32fc0a62b9e20dbf6499f8ebf4a5026fe05e28ce, and will be in the forthcoming v2.1 release.

Re: maximum footprint of application

How much of space will it consume ? Will the available memory (16MD Flash and 512 KB RAM) be sufficient ? Can the module safely operate without errors (stack overflow, insufficient memory,...) ? The default application size is 1MB in flash, if you use the default partition table layout (remaining f...

Re: same sdkconfig but different memory layouts

The section of memory which is missing in one of the logs is memory which is used for Bluetooth (some BT functions are in ROM, so they use hardcoded memory regions which are reserved at app boot time). https://github.com/espressif/esp-idf/blob/v2.0/components/esp32/heap_alloc_caps.c#L195 If Bluetoot...

Re: pvPortMallocCaps with MALLOC_CAP_32BI and memset

- Can I use MALLOC_CAP_32BITS to create array of float ? I'm not sure if floats are accesed only in 32 bits way. I'm fairly sure this will work. - When I try to create an array (float [64][64]) ) but I have no enough memory, the system don't crash but when I access to the array I write other parts ...

Re: Importing /usr/include into the ESP project

The /usr/include directory has socket code for PC Linux. It won't work in ESP-IDF.

Can you be more specific about what you're trying to do, and the errors/problems you're seeing? Some sample code or screenshots may help.

Re: ESP32 Networking unreliable? Could it be more modular?

Hi mgleason, The problem is I'm seeing the same behavior all the time. It may fail 3-times in a row. Each time I hit the reset button (I'm not re-compiling), and reboot and it fails... Then maybe the forth time it'll work... Putting it in a re-try loop doesn't seem to help - once it's failed, it alw...

Re: Constant reboot and "Could not auto-detect Flash size" when flashing

From the symptoms, I'd guess one of these problems (most likely first): ⋅  Cold joint on the SPI flash signal connections (at either the ESP32 or the SPI flash chip) ⋅  Power problems with the SPI flash rail (brownouts or a cold joint somewhere in the power rail or decoupling.) &...

Re: Hi , all , is there any function to disable the gpio function of specific pin in esp32..??

Switching the pin to an input with gpio_set_direction(gpio, GPIO_MODE_INPUT) or gpio_config() will disable the output driver and put the pin into a Hi-Z state. This is probably the closest you can do to "disabling" the pin.
