H A D | README | dc02badab480563b0bf9d3908046ea9d6b22ae63 Tue Nov 15 09:00:04 CST 2011 Heiko Schocher <hs@denx.de> arm, davinci_emac: fix driver bug if more then 3 PHYs are detected
since commits: davinci: emac: add support for more than 1 PHYs 062fe7d332c28ede25626f448681e43d76bb312e
davinci: remove obsolete macro CONFIG_EMAC_MDIO_PHY_NUM fb1d6332b5430b90a8fa8ebab709f33a60e9f816
I get following warning on the enbw_cmc board:
Err: serial Net: 5 ETH PHY detected miiphy_register: non unique device name 'KSZ8873 @ 0x01' DaVinci-EMAC Hit any key to stop autoboot: 0
Also I see some debug printfs:
=> run load + emac_close + emac_ch_teardown - emac_ch_teardown + emac_ch_teardown - emac_ch_teardown - emac_close + emac_open - emac_open Using DaVinci-EMAC device
reason is 062fe7d332c28ede25626f448681e43d76bb312e new define MAX_PHY. This is set to 3! I get on this board 5 active phys, so this leads in wrong memory writes ...
so I changed:
- define CONFIG_SYS_DAVINCI_EMAC_PHY_COUNT to set the MAX_PHY value, add a description in README for the new CONFIG_SYS option. - print an error message if more then MAX_PHYs are detected. - fill the active_phy_addr array in a for loop with 0xff - changed printf() in debug_emac()
