And finally the final chord, after restarting the Eclipse nothing else works. It's probably time to go back to v3. 2. 2. At least through the ass, but everything worked.

Thank you , installing Eclipse 12-2018 helped. I was able to open my project from v3. 2. 2 But there are problems with include. Files are visible , but errors appear during compilation.

Its all work

This does not work again at the first installation step. It seems that manufacturers do not want to sell and maintain their products. Very sad. Two days have already been lost to upgrade from esp-idf-v3. 2. 2 to esp-idf-v4.0

esp-idf-v4.0 more dont work with eclipse?

I try to setup esp-idf-4.0
esp-idf-tools-setup-2.2
Installation has failed with exit code 1

I see that the triple-DES encryption and decryption functions are described in the IDF. Where can I see a Triple-DES example?

Thanks, placing all the functions of can driver initialization, CAN start, CAN driver deinitialization, and can stop in one task, and binding this task to one CPU core solved the problem.

Would it be possible for you to post your .elf file. I want to see the full backtrace of both CPUs. # xtensa-esp32-elf-addr2line -e C:/Users/Alex/Desktop/workspace/esp32/build/ltc.elf 0x4008a5b8:0x3ffce750 0x400889f4:0x3ffce770 0x40089997:0x3ffce790 0x400d289a:0x3ffce7d0 0x400d294e:0x3ffce7f0 0x400...
