Re: On the freeness of a BLOB-containing driver

The reason for this is not only the additional cost of the flash chip,

you would have to add a programming device, possibly a dual power supply
to drive it and you would need anyway some intelligent enough code on a
ROM to allow emergency recovery from bad flashing.

Certainly there are AVR and ARM chips that do glue-less downloading from serial FLASH chips at boot time. Atmel sells them, among others. Reprogramming of the FLASH is done via JPEG and not under the embedded processor's control.
