Hi all,
Our board has eTSEC1 connected to a Realtek RTL8305SC switch (PHY MII
mode). eTSEC1 says that all packets received has CRC errors, but the
packets are OK. U-Boot says: "Got error 4".
If I ignore CRC status, I can load Linux kernel, but the driver
Gianfar also says that received packets has CRC errors.
Is there any register that can tell me something more about eTSEC
timing/clocking? If the packets are OK, dont know why its accusing CRC
error...
Some regs dump:
RCWLR: 0x26040000
RCWHR: 0xa4600c02
OBIR: 0x30100000
SCCR: 0xffd7ffff
MACCFG1: 0x00000000
MACCFG2: 0x00007105
IPGIFG: 0x40605060
EDIS: 0x00000000
ECNTRL: 0x00001000
Im using u-boot-2009-11
Any help is welcome,
