Sorry, I am not trying it on an original LogicPD board. Our board is based in i.mx27 ipcam. We have a different phy which is in 0x0 address instead of 0x1F and we have also a different NOR flash model. We have also the external 32KHz xtal at 32.768 KHz. - The init code for our sdram is different as we have different model and memory configuration, however I made a memory test and all seems fine. - I adapted NOR flash configuration and PHY_ADDRESS only, and experienced the previous problems. I could expect issues with NOR flash but I don't know why I could have any issue with ethernet. > >> Have you experienced these problems also? > > No, we didn't. > > Best regards, > > Wolfgang Denk > > -- > DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de > Monday is an awful way to spend one seventh of your life. > -- Javier Martin Vista Silicon S.L.
