Compiling error

bremby · January 3, 2022, 11:16pm

Hi,

I started to see this warning, is there something I have to do to fix it? or is something in the ESPHome queue that will be addressed with the next release?

I have the same problem. PRogramming interupted with ESP32.

I found a similar message on another library

I have this message also, and the ESP32 complied code does not boot correctly after flashing the binary via USB serial.
Here is a snippet from the compiler log including a couple of lines before and after the error, plus some of the ESP32 serial log.

Source code verifies fine in ESPhome. Is this likely to be a coding problem in my ESPhome code, or the compiler ?

Compiling does complete, but I get this from serial terminal after the ESP32 reboots.

Hey can anyone recommend where I should repost this sort of low level issue ?

I’ve checked over my ESPhome code as best as I can, and it Validates fine, but as above, it hits a compiler error AND the binary does not run on the ESP32. I need to find some help to progress to a solution, just not sure where to ask as it seems here might not be the best place in hindsight…

I have the same issue and found this on Github:

github.com/platformio/platform-espressif32

esp32-hal-spi.c doesn't compile with 3.2.0

help wanted

Hi! I've recently updated the platform to release 3.2.0 and my code doesnt' c…ompile: ``` C:\Users\luca\.platformio\packages\framework-arduinoespressif32\cores\esp32\esp32-hal-spi.c: In function 'spiTransferBytesNL': C:\Users\luca\.platformio\packages\framework-arduinoespressif32\cores\esp32\esp32-hal-spi.c:922:39: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] uint8_t * last_out8 = &result[c_longs-1]; ^ C:\Users\luca\.platformio\packages\framework-arduinoespressif32\cores\esp32\esp32-hal-spi.c:923:40: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] Compiling .pio\build\lolin32\FrameworkArduino\main.cpp.o uint8_t * last_data8 = &last_data; ``` If I revert to 3.1.1, everything works fine. Thanks

It seems like the fix is simple and already in place in arduino-esp32 version 2.0+. Not sure where and how to have ESPHome pick up that new version.

having same issue

if I do the initial esp32 install it works just fine , do a edit that involves a rebuild it just gets stuck in a boot loop
