Re: vTaskDelete sometimes hangs current task

Hi maldus, Sorry, this is too much code for us to try and use it to debug an OS-level bug. If you have a simple example (maybe by deleting code from this example until it's only a few short source files), then we can happily look at it. But maybe someone else from the forum can help. I did notice on...

Re: [Answered] How to build a subset of the possible components in ESP-IDF?

Are we going to support for LTO in few months time. GCC compiler supports it on other platforms. I am hoping it will reduce bin size by at least half. Hi Matej, We don't have any update about LTO, but it will not be supported in the near future. We've done some experiments, but ESP-IDF relies heavi...

Re: vTaskDelete sometimes hangs current task

Is it possible the task handle is corrupted and it doesn't point to a valid task at all? This could result in the behaviour you describe. Are you certain that the main task is blocking in vTaskDelete() and not in some nearby function, for example if a task is deleted while holding the semaphore that...

Re: I cannot write to register associated with HSPI

You have to clear the reset bit for the peripheral as well as set the clk_en bit.

Is there a reason why you need to write the registers directly, rather than calling periph_module_enable(PERIPH_HSPI_MODULE); ?

If it's still not working, can you please post the code that you're using?

Re: Flash encryption without secure boot

Hi user4, 1. Is it then impossible to disable flash encryption per the steps at https://docs.espressif.com/projects/esp-idf/en/latest/security/flash-encryption.html#disabling-flash-encryption ? Yes, if FLASH_CRYPT_CNT is write protected then this is impossible. 2. Will I still have three more serial...

Re: Compatibility between "normal CMake" and ESP-IDF

Hi permal, Edit: build-esp32.sh in examples/build_system/idf_as_lib is hard coded for Ninja, on Linux make is usually the preferred tool. This should also work with make, if you change the shell script. (BTW, you might find that you like ninja - I'm a Linux user and I am 100% converted to it - build...

Re: Will ESP32-WROOM-32U be damaged if operated without an antenna?

Hi Phil, It can be damaged, and for this reason it is not recommended to any enable RF transmission without a suitable antenna connected. Anecdotally, I ran an ESP32 without an antenna connected for a while (without noticing) and it seems to be fine. But this is not a guarantee that all such cases w...

Re: how to fix: OSError: [Errno 71] Protocol error

Hi nobbynobby, Looks like you're doing everything correctly. The errno 71 "protocol error" usually means something went wrong at the USB link. You can try looking in the kernel log (dmesg or "journalctl -k") to see if there are any USB-related kernel errors at the same time flashing failed. I have a...
