IOS upgrade

[Richard561]

I am planning on upgrading another 4221 Router to bengaluru-17.6.5. The current Ios is 16.09.07.  Also, this is from the show platform:

Slot      CPLD Version        Firmware Version

--------- ------------------- ---------------------------------------

0         19042420            16.7(5r)

R0        19042420            16.7(5r)

F0        19042420            16.7(5r)

Am I correct in assuming that I will need to perform a “upgrade hw-programmable cpld filename bootflash:isr4200_cpld_update_v2.0.SPA.bin” prior to upgrading the IOS to 17.6.5 ?

hello @Richard561,

To upgrade the IOS to version 17.6.5, it is generally recommended to ensure that the CPLD firmware is up to date.

You can use the "upgrade hw-programmable cpld" command followed by the filename of the CPLD firmware image. In your case, the command would be:

upgrade hw-programmable cpld filename bootflash:isr4200_cpld_update_v2.0.SPA.bin
