I've upgraded CPU to rev2.1, board rev0.3. Applied 5/5 patches onto paulus/powerpc.git at e403149c92a. Here is the results: If I use -rxid, then geth not able to transmit anything. With -txid geth not able to receive anything. With just -id everything works fine though... Maybe there should be another condition, in addition to cpu rev2.1? > Thanks, > > Kim > > mpc8360 rev 2.1 erratum #2: > ----------- > Recommended AC timings for chip 8360Rev2.1 UCC ETH RGMII when working > with Rev Pilot MDS for proper RGMII operation: > > IMMR_BASE + 0x14A8[4:5] = 11 (clk delay for UCC 2) > IMMR_BASE + 0x14A8[18:19] = 11 (clk delay for UCC 1) > IMMR_BASE + 0x14AC[20:27] = 10101010 (data delay for both UCC's) > > The Phy (Marvell 88e1111) should be configured NOT to work with RGMII > delay for TxD.
