PowerPC 8266 ADS-PCI(CPM8260) SCC (UART/Ethernet Mode) and SMC in UART mode

[Aung Soe]

Dear All

I am working on PowerPC 8266 ADS-PCI board

 with Montavista Linux with 2.4.20 Kernel to make SCC1, SMC 1& 2

in UART mode, SCC2, 3 & 4 in Ethernet mode, and FCC 2 in Fast

Ethernet Mode; all in NMSI and not TDM. The drivers provided with

2.4.20 Linux on Power PC were refered and reused.

http://lxr.linux.no/source/arch/ppc/8260_io/?v=2.4.20;a=ppc

 When there are only 3 SCCs used in Ethernet mode and the last

SCC in UART mode then the system works well.

But when 2 more SMC are added to the UART serial driver, the SCC

Ethernet network driver is not working after all ports working for a while.

I will be appreciate to hear any pointers and hints.

Thanks in advance.

Sincerley

Aung
