You can still stuff your app_main() full of vectors, maps etc but you must do as above (don't use { with app_main()). Well, I drag the exact same code, no work (same ...

While I did not flash a device to do a test run (I am sure it will work fine); This works perfectly fine for me (both as C and as C++). #include <stdio.h> #include <tinyexpr.h> #ifdef __cplusplus extern "C" #endif void app_main() { printf("%f\n", te_interp("5*5", 0)); /* Prints 25. */ } I suspect w...

Hi Vincent, the issue is that I flashed the bootloader already in 'One-Time Flash' mode and would need to re-flash the bootloader with Flash Encryption enabled in order for this to work? Unfortunately that's correct. Flash encryption is enabled by the bootloader during first boot, so you need to co...
