Re: strange behavior with use of cpu=0 for application Tasks

I've seen similar behavior on a device I'm developing on a custom board that has a piezo for beeps and an RGB led. When wifi is connecting for, the piezo/led will stutter, even though they are being driven by FreeRTOS timer callbacks. I believe this may be caused by wifi blocking both cpu 0 and cpu...

strange behavior with use of cpu=0 for application Tasks

Hi,

I was using cpu=0 for both wifi and LWIP
cpu=1 for rest of my threads which are about 4 with same priority=6.

I move my TCP/UDP data process thread from cpu=1 to cpu=0 then I got strange behavior with my LED flashing stop working properly.

Can i use cpu=0 for my application Task?

Erm, you know that you can select panic behaviour in 'make menuconfig'? Restarting quietly is one of the options there.
I cannot see this option.

Re: overwrite weak function not working always

So yes, that is the issue you have. .c or .cpp shouldn't matter. Can you see if this solves the issue for you? yes it solve for if define in main.c/main.cpp. not elegant but works. Can i do esp_restart within this override function. I do not want default behavior which is panic handler just stop de...

Do i need to define in .c file instead of .cpp It is working for when I defined in my C++ main.cpp file as but i define in new file e.g...

Re: SD card interface high speed mode

Can some one reply and share your experience.

Why big heap memory allocation when read files using SD card interface. Can we avoid it. Can some one point me out line of which allocate this heap. I am hoping to use stack and read file chunk by chunk.
