VTP

For general information, see archlinux.

BOOT image

Boot image contains two files: BOOT.bin and env.bin. They can be found in /boot directory on any of existing VTP boards. To make new microSD card, copy those two files to that card.

packages installation

Reboot the kernel with the root partition mounted 'rw' instead of 'ro':

1. Reboot

USE TSCONNECT:
2. Interrupt the U-boot when you see this:
  Hit any key to stop autoboot: 

3. Print out the environment variable 'bootargs'
  Zynq> printenv bootargs
bootargs=console=ttyPS0,115200 ip=:::::eth0:dhcp nfsroot=129.57.167.16:/vol/diskless/ArchLinux/armv7-devel/root uio_pdrv_genirq.of_id=my-uio ro
 rootwait cma=384MB

4. Change the 'ro' to 'rw'  (may need to copy in parts)
  Zynq> set bootargs "bootargs=console=ttyPS0,115200 ip=:::::eth0:dhcp nfsroot=129.57.167.16:/vol/diskless/ArchLinux/armv7-devel/root
   uio_pdrv_genirq.of_id=my-uio rw rootwait cma=384MB"

5. Boot (DO NOT SAVE ENVIRONMENT VARIABLES)

  Zync> boot

6. Login as root (through tsconnect or ssh) to use pacman.  Usage:
 
  https://wiki.archlinux.org/index.php/pacman

7. Reboot when done.  OS should come back with root fs in Read only mode.

How to configure new VTP

In diskless directory, create snapshot directory for the new VTP, for example for adchycal2vtp (have to do it manually, may be improved in future):

ssh root@clon00
cd /mnt/admin/clonfs1-diskless/ArchLinux/armv7-devel/snapshot
tar xvf templete_vtp.jlab.org.tar
mv templete_vtp.jlab.org adchycal2vtp.jlab.org

Using adapter, copy two files from existing microSd card to the new one: BOOT.bin and env.bin. Preferably, use existing card from test setup VTP, and not from the Hall, to avoid possible conflicts while MAC and IP on the new VTP are not corrected yet.

Place microSD card into new VTP, and install VTP in place. Register new VTP MAC and IP in JNET, and update $CLON_PARMS/vtp_mac_addresses.txt file (that file used by streaming daq only, but still good to have all MACs in one place).

Connect by serial line (tsconnect <vtp_ip_name>), reboot crate, click <Enter> during countdown. Update MAC and IP, for example for adchycal2vtp:

Zynq> printenv
Zynq> setenv ethaddr ce:ba:f0:03:00:c5
Zynq> setenv ipaddr 129.57.68.247
Zynq> saveenv

Reboot crate.
