I today looked at an issue posted in the lazarus forum:
https://forum.lazarus.freepascal.org/index.php/topic,60790.0.html
the user is unable to use ctrl-space for help because codetools cannot
find the required unit rp2040.
I could not reproduce the issue with my older installation of
lazarus-trunk but when I upgraded to latest trunk from today I saw the
same issue.
Possible reason is that lazarus cannot extract the info about the unit
source file from the output of the -ix format of fpc
I commented out a few log entries and got this result:

### TCodeToolManager.HandleException: [20170421200056] "unit not found:

when I manually run the -ix command with my fpc I receive the hits I
would expect:
~/fpcupdeluxe/fpc/bin/x86_64-darwin/fpc -Tembedded -Parm -ix | grep -i
rp2040
<controllertype name="RP2040" controllerunit="RP2040"/>
<controllertype name="RASPI_PICO" controllerunit="RP2040"/>
<controllertype name="FEATHER_RP2040" controllerunit="RP2040"/>
<controllertype name="ITZYBITZY_RP2040" controllerunit="RP2040"/>
<controllertype name="QTPY_RP2040" controllerunit="RP2040"/>
<controllertype name="TINY_2040" controllerunit="RP2040"/>
and I also find the unit in my fpcsrc directory:
find /Users/ring/fpcupdeluxe/fpcsrc -name "rp2040*"
/Users/ring/fpcupdeluxe/fpcsrc/rtl/embedded/arm/rp2040.pp
I am stuck because I cannot find the correct implementation for
TCTGetCompiledUnitFromSet althoug I searched through all sources for
(const UnitSet, AnUnitName: string)

Please note that you will not find unit rp2040 in official trunk, only
in my version but the same issue should be there for any other existing
embedded comtrollerunit
