My understanding is that there are, broadly
speaking, two distinct
methods for using Flashrom:
1. The chip being read or flashed is part of the circuitry on the
motherboard that is hosting the OS that is running the Flashrom
2. The chip being read or flashed is *not* part of the circuitry on
the motherboard that is hosting the OS that is running the Flashrom
instance. Instead, that chip is being accessed via a programmer of
some kind (e.g. a Bus Pirate, or BeagleBone Black, or suchlike).
This second method can be further subdivided:
2(a). The chip being read or flashed is connected to a circuit other
than the one being used to program it. For example, it might be a BIOS
EEPROM chip that was soldered to a motherboard by a PC manufacturer,
and which has not been removed from that motherboard.
2(b). The chip being read or flashed is *not* connected to a circuit
other than the one being used to program it. For example, it might be
a brand new chip that has been inserted into a programmer's ZIF socket
so that it can be programmed.
I would be grateful to know if terminology exists that would
unambiguously identify which method is being referred to, out of 1,
2(a), and 2(b).
ISP (or sometimes ICSP) refers to 2(a).
Thanks. Good to have corroboration of that.
Method 1 would be internal programming (cf.
programmer), software programming, or specifically programming from the
host CPU (vs. programming from another in-circuit flash master like the
Intel Management Engine). Any of these terms are likely to be
understood, though flashrom typically goes with "internal" programming.
Thanks. Good to have a term for method 1.
In any case, these flashing methods and terms also
aren't specific to
flashrom and can apply in other flash memory programming contexts.
I suspected as much; good to have corroboration.
Is there a term that unambiguously describes method 2(b)?
