[U-Boot-Users] MPC5200 + multi serial chips (16554)
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_ ???
May I manage the serial ports with setserial linux program or I have to develop a new device driver?
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.]

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

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.
