Hi Everyone ! I've got a TS7260 64 Mo RAM and I want to boot from a SDcard. I follow step by step the jywmpg's method but I meet a problem. After the RedBoot configuration : load -r -b 0x00218000 -h 192.168.1.12 zImage-7260_2k-ts11 load -r -b 0x00600000 -h 192.168.1.12 ts7260-sdcard-initrd-1.02.gz exec -r 0x00600000 -s 448760 -b 0x00218000 -l 685808 -c "console=ttyAM0,115200 root=/dev/ram0 init=/linuxrc rw" Everything's seems to be ok with TFTP downloads but after exec command I've this error message : [.....] Searching for NAND flash... NAND device: Manufacturer ID: 0xec, Chip ID: 0x75 (Samsung NAND 32MiB 3,3V 8-bit ) SEVERE WARNING: This module is known to have data corruption problems when used with 512 byte sector NAND flash!!!<5>Using static partition definition Creating 3 MTD partitions on "NAND 32MiB 3,3V 8-bit": 0x00000000-0x00004000 : "TS-BOOTROM" 0x00004000-0x01d04000 : "Linux" 0x01d04000-0x02000000 : "RedBoot" NET4: Linux TCP/IP 1.0 for NET4.0 IP Protocols: ICMP, UDP, TCP, IGMP IP: routing cache hash table of 512 buckets, 4Kbytes TCP: Hash tables configured (established 4096 bind 8192) NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
