RE: running 8xx without UART

Hi,

there appeares to be a microcode patch for MPC862 that allowes relocating SMC, SPI and I2C Parameter RAM. This should help getting
SMC1 running while SCC3 is doing Ethernet.

Thanks, Stephan

Kein Problem :-)

this problem is actualy no kernel bug. It is a limitation of the 862 family that you can't use SMC1 while you use

SCC3 as ATM or

ethernet. It's not so well documented. Thant's why we run into that trap. The special problem on 852 is that there are

ony 2 SCC's

and 1 SMC. :-)

We are experiencing problems with SCC3 running ethernet and SMC1 as console interface on a 852.

SCC3 = Ethernet or SCC3 = ATM?

We are using SCC3 as ethernet (Actualy there is no ATM on MPC852. But I guess that doesn't make a difference). :-)
