Step 3:

After system is rebooted, verify the new CPLD version:

$ sudo cat /var/log/versa/versa-devmgr.log | grep -ia cpld | tail -n 5

2022-10-13 13:19:15.873 INFO  VER: CPLD:Version = 24

CPLD programming is DONE!

Method #2:

For VOS lower than 22.1.4 or build date older than Feb 8, 2025 (without hotfix 119728)

Step 1: 

Download the CPLD firmware update file from the link below

https://versanetworks.box.com/s/seswhklnkosr2zldojvsw32s4i7q7gkp

filename: CSG300_CPLD_0x32.tar.gz

md5sum: 86dda537f5c52ef6eabea498242ec8e7

Step 2:

Extract the CPLD firmware and update tools

[admin@versa-flexvnf: ~]  $ sudo tar -xf CSG300_CPLD_0x32.tar.gz 

Step 3:

Go to the CSG300_CPLD folder extracted and set execute permission

[admin@versa-flexvnf: ~] $ cd CSG300_CPLD_0x32

Release Notes: 

CPLD 0x32 (2/8/25)

    - Added CPLD platform watchdog feature in 22.1.4 (February 8, 2025 hotfix 119728)

    - CPLD 0x32 and update utility are integrated into VOS 22.1.4 (February 8, 2025 hotfix 119728)

CPLD 0x30 (6/11/24)

    - Fixed system boot up issue at cold environmental temperature ~ below 20C. When a unit is stored in an environment < 20C it can fail to power up - The problem is related to initial power-up of the appliance when done at cold temperatures. Indication of this is evident from observing that the two white LEDs and Blue LED are lit. Units that are already installed and up and running are expected to have no runtime issues. 

In case CSG300 appliance does not power-on immediately, due to being stored in a cold environment,  move the appliance to a warmer environment (>20*C/ 70*F), once unit is at room temperature,  power-cycle the unit (dis-connect AC power and reconnect AC power to the power adapter). Our experience is that units should be able to power-on once at room temperature. Once the appliance is powered-on, we can upgrade the CPLD following the above process. 

CPLD 0x24 would fix most of the brown out issue, and we haven’t seen any brown out issue since the CPLD was upgraded to 0x24. However, Power glitches, ESD, surge, etc. are unpredictable, so there still might be a small possibility of corner cases where these power glitches simulate system power down sequence or cause system to shut down (as a brown out)

Known issue: 

With CPLD version 0x20, there is a possibility that the NICs on the extension board (vni-0/4) and the management interface (eth0) may intermittently fail to be detected.
