11## Quickstart Installation via FPCUPdeluxe
22
33The easiest way to install Embedded Support for a huge variety of embedded controllers is to use fpcupdeluxe.
44
55Download latest(!!!) FPCUPdeluxe from
66
77[fpcupdeluxe releases on github](https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases).
88
99Make sure that you use a version \>= v1.8.2r of FPCUPdeluxe, the tutorial references features that are only in this and newer versions.
1010
1111As we are using trunk versions we highly recommend to create an extra installation for embedded targets so that issues in compiler/lazarus do not effect your other work.
1212
1313## Steps for people mainly interested in Wio Terminal or Raspberry Pico
1414
1515When your primary targts of interest are the Wio Terminal or the Raspberry Pico, then installation consists of entering an installation directory for fpcupdeluxe on top left and then selecting the speedbutton for 'Wio' or 'Pico' on the bottom of the screen:

1818
1919## Steps for people interested in other targets like arm avr or espressif microcontrollers
2020
2121For all other targets select embedded (or trunk.git) for fpc and trunk.git for lazarus.
2222
2323The reason to choose embedded would be to have support for more arm-embedded controllers that are currently not yet available in fpc trunk and installing trunk.git instead of stable lazarus is a good idea because debugging for embedded targets is much improved in lazarus trunk.
2424
2525For all platforms besides arm trunk.git is likely the best choice for both fpc and lazarus.
2626
2727To build your embedded version of Lazarus follow those simple steps:
2828
2929- Select the target directory for your installation
3030- Select embedded or trunk.git for fpc
3131- Select trunk.git for lazarus
3232
3333Hit the Install/update FPC+Laz button.

3636
3737After installation of FPC+Lazarus is done switch to the 'Cross' Tab
3838
3939In the Cross tab select the desired CPU and the desired OS und then click on the 'Set subarch' button to define the subarch that you would like to use:

4242
4343Now you can select 'Install compiler' button and the selected subarch will be installed.....
4444
4545You may repeat this step for all CPU's subarchs you wish to install.
4646
4747Some hints on Subarchs:
4848
4949- armv6m Subarch is good for Raspberry Pico, SAMD21 based board like the Arduino Zero or STM32F0/G0/L0 families
5050
5151- armv7m is for the Bluepill, Arduino Due or STM32F1/L1
5252
5353- armv7em is for the Wio Terminal, Blackpill or SAMD51 / STM32F3/F4/G4/H7/L4 families
5454
5555- avr5 is for Arduino Uno
5656
5757- lx6 is for ESP32 based boards
5858
5959## Install extra devel tools
6060
6161There is an extra module available to ease development by providing pre-compiled binaries for some usefull tools:
6262
6363For avr development:
6464
6565- avarice (gdbserver for several debug probes manufactured by Microchip)
6666
6767- bossac (upload firmwares to avr controllers)
6868
6969for arm development:
7070
7171- openocd (gdbserver for all kinds of debug probes)
7272
7373- st-util (gdbserver specially for st-link v2/v3 debug probes)
7474
7575for the Raspberry Pico:
7676
7777- openocd-picodebug (gdbserver for running a debug probe on the 2nd cpu of your pico)
7878
7979- openocd-rp2040 (gdbserver for using a 2nd pico as a debug probe)
8080
8181general:
8282
8383- gdb-multiarch (one gdb to debug all embedded archs available)
8484
8585- gdb-multiarch-8.3.1 (an older version of gdb that works better for avr)
8686
8787Install it by selection develtools4fpc on the Modules tab of fpcupdeluxe by selection develtools4fpc and clicking 'Install Module':
8888

89+![](/wiki-images/c/c7/Modules_devtools4fpc.png)
9090
9191the files will then get deployed to the ccr/devtools4fpc directory inside of your fpcupdeluxe installation
