Hi all, I am working with s3c6410 based board (with linux 2.6.28.6). I am using DM9000E chip as ethernet connected to 16 bit data bus (SROM_BC1). In u-boot ethernet works fine. But in the linux kernel (with the same SROM controller settings ) ethernet works unstable and very strange: In interrupt handler (dm9000_interrupt) received interrupt status has the value which not documented in DM9000 manual: int_status = 0xFE. After receiving interrupt with status (0xFE) I can't yet ping my board from host. But I can ping host from board with some delay, and only after this I can ping my board from host. If anybody has circuitry of DM9000 connected to S3c6410 and working DM9000 software driver, please help me. Thank you, Vitaliy Stolyarov. ------------------------------------------------------------------- List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php
