Alguém sabe o que pode estar a acontecer no esp32 para gerar este erro? Se alguém estiver disposto, posso disponibilizar o código.
Já verifiquei e não é nenhum tipo de erro a nível do hardware.

Answer 1

I came across this issue a couple of times. Sorry, my Portuguese is not perfect but I'll try to help in English.
This happens when we are trying to allocate more memory inside a function than we allowed it initially.
For example:
void task1(void *params)
{
char buffer[3000];
memset(buffer, 'm', 3000);
}
void app_main()
{
xTaskCreate(task1, "task1", 2048, NULL, 1, NULL);
}
Notice that xTaskCreate allows only 2048 bytes(This differs from vanilla freeRtos which uses word as the unit) but we are trying to use 3000 bytes
I hope this helps, if you can share a portion of the code that works with the memory, I can look more into it.
