can we use 4.0 stable idf with old makefile style ?

Are we forced to use the cmake and idf.py based build for compiling applications using stable 4.0 ?

I am more used to the old makefile style and want to migrate the code to 4.0.
Is it possible to use the makefile based build on 4.0 ?

i2c failing most of the time when light sleep is enabled and min freq 10MHz

My i2c is failing when I am enabling light sleep. Is this normal ? I am trying to achieve low power consumption in a mode but need to maintain the complete ram and task states. So I believe the light sleep is the only option for me. (correct me if I am wrong). In light sleep I am able to achieve aro...

can an esp-idf build app can run in any app partitions? (factory / ota)

Hi, I have a small question, does esp-idf build application have any thing to do with where it is going to be dumped inside the external flash ? Assume I have one factory and one ota partition which is of same size. Now, technically any same application code should be able to run from both of the pa...

recursively adding all source files in components directory using cmake setup ( esp-idf stable 4.0 )

Hello, I am having too many recursive folders in my project and all are in components directory. In new stable 4.0 I am trying to make the CMakeLists.txt is too confusing and I am not used to cmake based build. Could someone create an example for a CMakeLists.txt for recursive folder? Say I have com...

esp32 resetting when running code updated via ota but direct make flash running fine

Hi, I have some doubts regarding the esp32 ota. I customized the OTA for my requirement and I am using factory and ota_0 where factory is having my bluetooth bootloader. As of now all is fine but now I am finding my new firmware build is resetting if I do it via ota. Even I tried to load the app via...

malloc memory crashing for spi but global/static working fine

Hi, I am using esp-idf 3.3. If I use malloc to allocate a 3KB buffer, then the system is crashing. I already have around 60KB heap. I am using this buffer for LCD via spi. SPI is pushing it via DMA. If I use static/global 3KB instead, it works fine. ILI9341 initialization. Guru Meditation Error: Cor...

Preventing further writes to the fuse bits

Hi, I want to prevent further writes to fuse bits to prevent any future accidental writes. For example, I am using flash encryption but not secure boot. So in future if my program can write to the fuse bits by mistake, I don't to take a chance. So is there any way to freeze the current fuse bits to ...
