[U-Boot-Users] Erase in UBoot

[Bharathi Subramanian]

Hello All,

We are using UBoot 1.0.0, During continuous 2nd erase operation, the
no .of DOT is increased. I like to know whether this is something do
with UBoot or flash chip or is it normal behavior ??

ROM # erase B0100000 B07FFFFF
.............................................. done
Erased 111 sectors
ROM # erase B0100000 B07FFFFF
..................................................... done
Erased 111 sectors
ROM #

Thanks,

This is normal behaviour. The dots are printed  one  per  second,  so
they give an apprximation how long the erase takes. It is normal that
it  will  take longer and longer the older your flash gets (i. e. the
more rease cycles it has gone through)

In this case the increase was approx.  15%  which  is  poretty  long;
either  your  flash  is  brand new (burn in phase) or it's pretty old
(near end of life)?

Why don't you check the code. Looks like flash driver is putting dots 
based on time and the second erase is taking more time. Also, 1.0.0 is 
very old code now.
