Correct. It is most likely the cause. But - it would also be
interesting if you could measure the voltage Samuel, on pin 8
after having run flashrom in any mode.

Unfortunately (or fortunately, because that Broadcom data book is
probably difficult to find) TBL# (and often WP# too) is usually
connected to a GPIO on some chip. (And that chip may be easier to
find docs for.) But - this Broadcom chipset could have dedicated pin,
I'm not ruling it out.
