FUS default version programmed in STM32WB5CG has been upgraded to 1.1.0？

[lbo.1]

I got some STM32WB55CG samples from st office and the date code is 034. The read out FUS version is 1.1.0. Has the default firmware been upgraded? So the customer doesn't have to upgrade FUS anymore?

Considering the result of the read access at address 0x20030030, the FUS version is v1.1.1.  So it is really the most up to date one.

You don’t have to do anything regarding a FUS update.

Im sorry, but last FUS version is 1.1.0 not 1.1.1. or am I confusing something?

[Remi QUINTIN]

​Last official FUS version is v1.1.0 (released in the last CubeWB FW package) . But there is an internal version v1.1.1 that exists internally. As you got the chips directly from ST office, they may have been upgraded with this internal version before you get them.

[Vyacheslav]

Ok, thanks for responce, Remi.

So when it comes to bulk purchase in the future, what FUS default version programmed in it?

[Remi QUINTIN · Accepted solution]

​The trend is to have all devices pre-loaded with FUS v1.1.1 in the mean term but the process is done step by step, line by line, package by package, ...

So it is hard to give you an exact answer as it depends on what type of WB devices and when you'll purchase them.

Ok, thanks , Remi.

[Vyacheslav]

we have 1200 chips 512k flash and all have FUS 0.5.3 version, but we bought them for a long time ago

[Remi QUINTIN]

​Ok this is the expected FUS version on such devices when bought some time ago.
