[U-Boot-Users] which config to choose for MPC8347E cpu ?

[Fathi Boudra]

Hi,

I have a custom board with a MPC8347E and U-Boot doesn't have a config for
this cpu.
which config is more appropriate to use for my board ? (maybe MPC8349EMDS or
sbc8349 or tqm834x ?).

any tips ? TIA.

cheers,

Fathi

The schematic for the MPC8349EMDS is available on Freescale's web
site, and I believe TQS makes their schematics available too.  I don't
know about the SBC one (Wind River, maybe?).  Ultimately, compare
schematics to your board and choose the one that's most similar as a
starting point.  IIRC 8347 is a subset of 8349 (one less PCI bus or
something like that) so the 8349 configs should be fine.

regards,
Ben

Fathi,

there are 3 different MPC834x (3,7 and 9) which all have same silicon.
The difference is the package.

The 43 has a small package and the 49 a big one. The 47 is available in 
both. Package size defines PCI bus (small has 1x 32Bit, large has 64-Bit 
or 2x 32Bit) and memory bus width.

Which one do you have ?

I'm working with a 43 right now and it works fine.
My starting point has been the MPC8349EMDS.

I can share my config if you want to - please let me know.

regards,
Andr? Schwarz

Yep,

I started from mpc8349emds and worked further from there. Reminds me to
re-submit my board configs again after cleanup.

TQ only provisdes the schematics for the carrier board, but not for
the CPU modules.
