We have the MPC5200 MAC connected to the Micrel KS8995MA MII-SW port. The configuration pins of the 8995 are set to: SPI slave PS0=0 PS1=1 PHY mode MII SCONF0=1 SCONF1=0 SCONF2=0
The MII and SPI ports are working, checked with the uboot mii and sspi commands.
However, ethernet transmit and receive do not appear to work. Looks like the switch is not configured correctly and does not pass any data.
The manual initialisation sequence we are using is: sspi 0 24 020100 sspi 0 24 02024c sspi 0 24 020305 sspi 0 24 0204F1 sspi 0 24 020620 sspi 0 24 021061 sspi 0 24 022061 sspi 0 24 023061 sspi 0 24 024061 sspi 0 24 025061 sspi 0 24 025B18 sspi 0 24 0260FF sspi 0 24 0261FF sspi 0 24 0262FF sspi 0 24 0263FF sspi 0 24 0264FF sspi 0 24 0265FF sspi 0 24 0266FF sspi 0 24 0267FE sspi 0 24 020101
This was taken from the example: https://dev.openwrt.org/browser/trunk/package/spi-ks8995/src/spi_ks8995.c
Does anyone have an example that works?
