p1010 eTSEC and eTSEC MDIO map error

This problem appears relatively small probability. I let p1010 CCSR map in 0xffe00000,but,When many times to restart p1010 device ,   p1010'  eTSEC and eTSEC MDIO may  map error  lead to eth not normal, other ccsr space map is normal.  I read p1010'  eTSEC and eTSEC MDIO map region ,all is 0;  write is also not normal,  other space read and write is normal.

Hello  Zhang wenjian,


In u-boot, CCSR is also configured at 0xffe00000, please refer to the following memory dump on P1010RDB.

I think problem should be caused by the improper eTSEC configuration.

Please refer to the P1010 QorIQ Integrated Processor Hardware Specifications, 2.4 Reset Initialization and 2.5 Power-on ramp rate to ensure that all reset timings and power supplies ramps are correct.

Refer to the AN4534 - P1010 QorIQ Integrated Processor Design Checklist and check termination of all unused signals and signals having explicit termination requirements.
