Hello, I'm porting Android to imx51 target and I'm trying to write the file system to the internal target's NAND. I've tried several approachs but none of them did work! The las one is: -in the host: cd android_freescale/out/target/product/imx51_BBG mkdir ram cp -Rfp android_freescale/out/target/product/imx51_BBG/root/* ram cp -Rfp /android_freescale/out/target/product/imx51_BBG/system/ ram cp -Rfp android_freescale/out/target/product/imx51_BBG/data/ ram mkfs.jffs2 -n -r ram -e 128 -o rootfs.jffs2 cp rootfs.jffs2 /var/lib/tftboot -in uboot: BBG U-Boot > setenv bootfile uImage BBG U-Boot > setenv loadaddr 0x90800000 BBG U-Boot > dhcp BBG U-Boot > nand erase 0x00060000 0x260000 BBG U-Boot > nand write 0x90800000 0x00060000 0x260000 BBG U-Boot > setenv bootfile rootfs.jffs2 BBG U-Boot > setenv loadaddr 0x90B00000 BBG U-Boot > dhcp BBG U-Boot > nand erase 0x00360000 0x2A427CC BBG U-Boot > nand write.jffs2 0x90B00000 0x00360000 0x2DA0000 BBG U-Boot > setenv bootcmd_nand2 'nboot 90800000 0 60000;bootm' setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 wvga calibration init=/init root=/dev/mtdblock2 rw rootfstype=jffs2'
But I got this log: Loading from NAND 512MiB 1,8V 8-bit, offset 0x60000 Image Name: Linux-2.6.28-00007- gfa88f73-0058 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2196264 Bytes = 2.1 MB Load Address: 90008000 Entry Point: 90008000 ## Booting kernel from Legacy Image at 90800000 ...
