Sascha,
I've begun working on upgrading to the new environment, but I've
gotten stuck as far as getting Linux to boot. I've attached the
device list from the old environment and the new one that I'm
currently working on. I believe they are the same. My globals are
currently set up as:
version: 2015.02.0-00003-ga17b7cd-dirty
model: Atmel sama5d4ek
* hostname: sama5d4ek
loglevel: 7
console.input_allow: 1
bootm.image:
bootm.image.loadaddr:
bootm.oftree:
bootm.initrd:
bootm.initrd.loadaddr:
dhcp.rootpath:
dhcp.tftp_server_name:
dhcp.bootfile:
dhcp.oftree_file:
dhcp.vendor_id:
dhcp.client_id:
dhcp.user_class:
dhcp.client_uuid:
* autoboot_timeout: 3
* allow_color: true
* user: none
* boot.default: nand-ubi
* bootargs.base: console=ttyS0,115200
linux.bootargs.base:
linux.bootargs.console:
linux.bootargs.dyn.ip:
linux.bootargs.dyn.root:
editcmd: sedit
linux.mtdparts.nand0:
atmel_nand:256k(nand0.at91bootstrap),512k(nand0.barebox)ro,256k(nand0.bareboxenv),256k(nand0.bareboxenv2),256k(nand0.spare),512k(nand0.oftree),6M(nand0.kernel),-(nand0.rootfs)
With these settings, it says that it loads the kernel and is booting,
but then just sits there indefinitely. Any ideas? Below is the boot
information I get:
