[U-Boot-Users] MPC5200 + multi serial chips (16554)

[Andrea Sorio]

Hi

I have to develop an embedded system with a MPC5200 and
eight 16554 (32 serial ports). I'll use a chip seletec to manage the 
eight multi serial chips
with an external CPLD.
May I manage the serial ports with setserial linux program or I have to
develop a new device driver?

Thank you in advance

Best Regards

Andrea Sorio

Do you need to support all these 8 UART ports in _U-Boot_ ???

seterial is an application program that requires an  OS  to  run.  It
won't help you for U-Boot. [Yes, this is the U-Boot mailing list, and
we're discussing U-Boot issues here.]

Dear Wolfgang

Thank you for your replay.

No, I don't need them in U-Boot.

Yes, I know.
I would like to install u-boot and linux embedded in this board.
I hope that setserial could set up the linux serial device driver to 
manage the 32 serial
ports without any changes on serial driver. (I apologize for my english)

Thank you

Best regards

Then this is actually off topic here.

Your English is adequate.

Don;t expect setserial to be of any help on  a  non-x86  system.  You
will  have  to  tweak  at  least the mapping for the serial driver in
Linux. But as I said, this is off topic here.

Best regards,
