Hi, tnx things make sence now!
Did re-instal, for sure.
By sellecting PICO in fpcupdeluxe, FPC version chooses automaticly embedded, and LAzarus version automaticly chooses trunk.
Checked the pi PICO specs: Dual-core ARM Cortex-M0+
In Lazarus I went to options for project and choose:
Target OS-(T): embedded
Target CPU family (-P) arm
Target processor (-Cp) *
* there's only CORTEXM3 to choose
Just gonna try and see what happens...
