Unable to boot linux 4.9 on beaglebone green #109
Comments
|
Works here |
|
Double checked v2017.01-rc1 |
|
What's your u-boot setting ? It seems autoboot with tftpboot. But I cant do "saveenv" on v2017.01-rc1 . or should I edit /boot/uEnv.txt ? can you share it for us ? |
|
Wow, I found it. Just copy /nfs-uEnv.txt as uEnv.txt. set my own ip. It works. |
|
Sorry,I need reopen this issue. |
|
Good news, I solved this issue. and connmen ignore eth0 |
|
I realize the image file downloaded from the Beagle bone website is of type .img.xz. How can I convert to zImage or uImage format without using an SD Card even once? |

When a bonding interface is being created, it setups its mode and options. At that moment, it uses mode_lock so mode_lock should be initialized before that moment. rtnl_newlink() rtnl_create_link() alloc_netdev_mqs() ->setup() //bond_setup() ->newlink //bond_newlink bond_changelink() register_netdevice() ->ndo_init() //bond_init() After commit 089bca2 ("bonding: use dynamic lockdep key instead of subclass"), mode_lock is initialized in bond_init(). So in the bond_changelink(), un-initialized mode_lock can be used. mode_lock should be initialized in bond_setup(). This patch partially reverts commit 089bca2 ("bonding: use dynamic lockdep key instead of subclass") Test command: ip link add bond0 type bond mode 802.3ad lacp_rate 0 Splat looks like: [ 60.615127] INFO: trying to register non-static key.

[ Upstream commit 9f89c88 ] The func v4l2_m2m_ctx_release waits for currently running jobs to finish and then stop streaming both queues and frees the buffers. All this should be done before the call to mtk_vcodec_enc_release which frees the encoder handler.

Hi @RobertCNelson
I use your project https://github.com/RobertCNelson/ti-linux-kernel-dev build kernel 4.9.
But I boot from tftp server. It stop at "Starting kernel .."
Do you know the reason ?
