PIO core version selection

in chapter 5.4 of the core's docu it is stated that one should not anymore use

we use currently this lines to stay on core 2.7.3 to prevent any changes in the core influence our fw.

while it works for now and we are thinking now to switch to core 3.3.0 the question arises what to do to keep core 3.3.0 in a reproducable and not deprecated way..

@maxgerhardt you have some hint for us?

[maxgerhardt]

That way of doing it is still okay for purposes of reproducability. Before the packages were in the registry, that was needed, but not now it's not needed anymore for regular "just use the latest version" purposes, but still perfectly fine for fixing versions.

Just note that if you want to fix the toolchain, the package is now called toolchain-rp2040-earlephilhower, not toolchain-pico. It can be sourced from the same https://github.com/earlephilhower/pico-quick-toolchain/ toolchain though. Same goes for tool-mklittlefs-rp2040-earlephilhower if your project explicitly uses the LittleFS mklittlefs tool / data folder upload.

Thanks for the quick reply! To be honest I do not fully understand what all these options exactly do.

I thought all neccessary tools ship with the core?
Do I need something in addition to that?
