[U-Boot-Users] BDI2000 not good for ARM946?

[U-Boot-Users] BDI2000 not good for ARM946?

[Shawn Jin]

Hi,

I know this is out of the topic of this mailing list. But I really
need some comments on this issue and I know that this probably is the
best place to get a quick feedback for BDI2000 since a lot of ppl here
use it.

Some people using BDI2000 to bring up ARM946 board have a little
complaint that BDI2000 works flakey on their board. (It took them a
week to figure out its configuration file and sometimes it just simply
doesn't work.)

However my experience on ppc bring-up tells me that BDI2000 works
perfectly. So I'm wondering if this is an individual case for ARM
bring-up. Or BDI2000 for ARM is not as good as for PPC?

Please share your experience.

Best regards,
-Shawn.

Dear Shawn,

It takes some understanding of the hardware to come up with a working
BDI2000 configuration file. And of course the stability of the system
BDI2000-target depends on _both_ components, the  BDI2000  _and_  the
target.

My guess is that these people have little  experience  and/or  flakey
target hardware.

We use the BDI2000 on PowerPC, MIPS and ARM. I remember only one case
when a specific version of the firmware had problems  (and  this  got
replaced  by  Abatron  within  a  few  hours). In all other cases the
BDi200 has proved to be absolutely reliable  and  stable.  I  see  no
difference whether on ARM, MIPS or PowerPC.


Best regards,
