CSG1500 CPU CPLD firmware upgrade : Versa Support

CPLD Upgrade Procedure

Note: System needs to be power-cycled after CPLD upgrade for the new BIOS and CPLD to take effect.

1. Download and the extract the latest CPLD files from below link required for upgrade procedure

CSG1500 CPU CPLD V09

Versa_20220512-VDD09_vme.vme

https://versanetworks.box.com/s/sh0recz320npjtzw4gaunqq8s4gsl4yq

2. Copy below files to DUT into /var/tmp directory

cpldupd
cpldutil
Versa_20220512-VDD09_vme.vme

3. Check the current CPLD version once before upgrading as shown below

vsh connect vsmd
show chassis cpld info cpu
exit
CPU CPLD is highlighted in yellow

vsm-vcsn0> show chassis cpld info cpu

4. Assign cpldupd and cpldutil binaries executable permission from /var/tmp directory

sudo chmod +x cpldupd
sudo chmod +x cpldutil

5. Stop Versa services with following command

vsh stop

6. Execute following command to upgrade the CPLD on the system

sudo ./cpldupd -u CPU_SKX Versa_20220512-VDD09_vme.vme
Upon successful completion of upgrade below output should be seen

[admin@versa-flexvnf: ~] $ sudo ./cpldupd -u CPU_SKX Versa_20220512-VDD09_vme.vme

7. Once Upgrade procedure is completed, powercycle the system (unplug the power cords, wait for 10 seconds and plug them back in)

8. Verify the CPLD version after powercycleing the system

vsh connect vsmd
show chassis cpld info cpu
CPLD version should be changed before and after upgrade
