Hello, Linux is able to uncompress into SDRAM. We mapped SDRAM from 0x0. It is getting stuck at mounting root fs. We have mounted the root fs by NSF. Possibly it is not able to contact the server where it's FS is mounted. Pls find the following log and help me to bring up Linux. Our board has single ethernet and uses FCC1 with LXT971 driver. The board does not have BCSR.
