Tool/software: Linux
I have been googling but my knowledge about linux is limited and cannot find anything about this issue (even on TI forum). I attach environment variables from uboot and UART0 console output.
This is little overview steps I have done.
- My dev kit is BBBW.
- I set up a virtual machine (Ubuntu 12.04) under virtualbox where I want to set all tools needed for development.
- I followed the TI official wiki pages about building U-boot and Linux.
- All servers (DHCP, TFTP, NFS) are running and I am able to mount the rootpath and read and write from/to it.
- ufw inactive.
- /etc/exports
- /export/rootfs/ *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
- U-boot has static IP 192.168.2.3 and this IP is also passed to kernel.
- I had to add USB-Ether gadget driver into kernel so it can mount NSF FS.
- I didn't add initramfs into kernel due to mounting FS via NFS.
- As a filesystem I'm using original tarball from sdk (tisdk-rootfs-image-am335x-evm.tar.xz). If I create a SD with this filesystem it boots properly!
- I installed modules from kernel to filesystem.
- BBBW loads successfully u-boot, zImage and dtb via TFTP. It also mounts filesystem via NFS (at first place).
And these are my results and observation.
- It freezes in boot process with this message: [ 25.922728] nfs: server 192.168.2.1 not responding, still trying
- The kernel stuck right after message [ OK ] Started Network Service.
- Targets heartbeat led is blinking aprox 2 times faster.
- Some files and folders required by BBBW over NFS are not placed in rootpath. (Ex.: /etc/ld.so.preload, /etc/inird-release, /proc/self, /proc/vz, /etc/adjtime, /systemd/system.conf.d,... )
- If i tried to use initramfs as NFS filesystem, target booted properly.
Could it be caused by using virtual machine as a host? I would appreciate any help including tutorials how to get deeper into embedded Linux development.
Many thanks
