A small user program that reads or writes one address, by default 0x3fc98000, the base of the ESP32-S3 kernel DRAM region. A user process must not reach it, so the access must fault and only the process must die. "pffault w" makes the access a store, and a second argument names another address. With CONFIG_ESP32S3_PAGEFAULT and CONFIG_ESP32S3_PAGEFAULT_SELFTEST on the kernel side, "pffault r 0x80000000" exercises the recoverable-fault restart path, and "pffault r 0x0" the report path.
