Though toasters must be among the many most boring home equipment in a family – with maybe only a concentrate on making their toasting extra deterministic moderately than someplace between ‘nonetheless frozen’ and ‘charcoal’ – one way or the other firms maintain churning out toasters that simply add very complicated ‘sensible’ options. In fact, if a toaster provides a giant contact display screen and important processing energy, you might as effectively run DOOM on it, as was [Aaron Christophel]’s reflexive response.
Whereas unboxing the Aeco Toastlab Elite toaster, [Aaron] is positively dumbfounded that they didn’t additionally add WiFi to the factor. Though on the brilliant facet, that ought to imply no firmware updates being pushed through the web. In the course of the disassembly it may be seen that there’s an unpopulated pad for a WiFi chip and an antenna connection, making it clear that the PCB is a basic function PCB that can see use in different home equipment.
The SoC is marked up as a K660L with an exterior flash chip. Dumping the firmware could be very simple, with extremely accessible UART that spits out a ‘Welcome to ArtInChip Luban-Lite’ message. After some reverse-engineering the SoC turned out to be a rebranded RISC-V-based ArtInChip D133CxS, with a really usable SDK by the producer. From there it was simple sufficient to get DOOM to run, with the bonus function of needing to finish a degree earlier than the toaster will give the slice again.
