RE: MPC852T with SCC3 and SMC1

Hi Torsten,

I did all my tests in PPCBoot bootloader since I don't expect any additional problems in Linux.
Attached you can find a patch for cup/mpc8xx/serial.c in PPCBoot.

Regards, Stephan

Hello Stephan,

thanks for your help.
Do you made changes in the Linux uart.c driver
to work with the relocated data structures?

Regards,
Torsten

Hi Thorsten,

you should look for a 860 microcode. It's a microcode that
allowes relocating SMC, I2C and SMC. I already did some tests
with it on
a 852T and it finaly worked fine. But I had a lot of trouble
getting PPCBoot running on it but that was due to some a giant array
allocated on the stack (console buffer).

Hello all,

At one of our boards were using the MPC852T.
It will use the SMC1 as UART _and_ SCC3 with ethernet.
(SCC4 will also run  ethernet.)
I know that SCC3 will overlap the Parameter RAM of SMC1 and
I guess that there is a microcode patch to relocate the SMC1.

There is already a microcode patch mentioned in the 8xx_io/

directory

but it doesnt work at my board. Somebody uses this

microcode to relocate

quoted

SMC1? (to which address?)

I also tried to find a microcode patch for MPC852T
at the motorola web-site but without success.
Can anybody give me a hint where to find this microcode?

Thanks for your help.

Best regards,

Torsten Demke
