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?
Regards to all uboot-ers,
Chris
