Hello all, I need help regarding the bootup of linux on MPC8360 MDS Board.
After doing tftp the uImage from u-boot, with the bootm command the kernel gets uncompressed and stops there. The serial output from kernel could not be seen. Source being used: uboot - U-Boot-1.1.3 linux - Linux-2.6.11 supporting mpc8360epb. board - MPC8360 MDS The dump is below: U-Boot 1.1.3 (ppc83xx-20050315-dev) (Dec 14 2005 - 09:37:59) MPC83XX Clock configuration: Coherent System Bus: 264 MHz Core: 528 MHz QE: 396 MHz Local Bus Controller: 264 MHz Local Bus: 66 MHz DDR: 264 MHz DDR Secondary: 264 MHz I2C: 264 MHz CPU: MPC83xx, Rev: 20 at 528 MHz Board: Freescale MPC8360EPB I2C: ready DRAM: SDRAM on Local Bus: 64 MB DDR RAM: 256 MB FLASH: 16 MB In: serial Out: serial Err: serial Net: FSL GETH0 Hit any key to stop autoboot: 0 => printenv bootcmd=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netrramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loarnfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netrbootdelay=6 baudrate=115200 loads_echo=1 ethaddr=00:04:9f:11:22:33 eth1addr=00:E0:0C:00:7D:01 hostname=unknown loadaddr=200000 netdev=eth0 consoledev=ttyS0 ramdiskaddr=400000 ramdiskfile=ramfs.83xx ethact=FSL GETH0 filesize=2d030a fileaddr=20000 gatewayip=192.168.3.1 netmask=255.255.255.0 serverip=192.168.3.81 bootfile=/tftpboot/vmlinux.gz ipaddr=192.168.3.253 stdin=serial stdout=serial stderr=serial Environment size: 1005/8188 bytes => setenv bootargs console=ttyS1 root=/dev/ram => tftp 200000 uImage_test Auto negotiating done switching to rgmii 100 duplexity: full mac speed set to: 100 Using FSL GETH0 device TFTP from server 192.168.3.81; our IP address is 192.168.3.253 Filename 'uImage_test'.
