Chithunzi chojambulidwa cha ma board a Raspberry Pi chilipo kuti chiyesedwe, kutengera Debian GNU/Linux ndipo chimaperekedwa ndi gulu la firmware lotseguka kuchokera ku projekiti ya LibreRPi. Chithunzicho chidapangidwa pogwiritsa ntchito nkhokwe zokhazikika za Debian 11 zamamangidwe a armhf ndipo zimasiyanitsidwa ndi kuperekedwa kwa phukusi la librepi-firmware lokonzedwa pamaziko a rpi-open-firmware firmware.
Chitukuko cha firmware chafikitsidwa pamlingo woyenera kuyendetsa desktop ya Xfce. Mu mawonekedwe ake apano, fimuweya imapereka dalaivala wa v3d wa VideoCore graphics accelerator, 2D acceleration, DPI video, NTSC video (composite output), Ethernet, USB host, i2c host ndi SD khadi pa Raspberry Pi 2 ndi Raspberry Pi 3 board. Zina zomwe sizinagwiritsidwebe ntchito zikuphatikiza kuthamangitsa mavidiyo, CSI, SPI, ISP, PWM audio, DSI ndi HDMI.
Tikumbukenso kuti ngakhale kukhalapo kwa madalaivala otseguka, ntchito ya VideoCore IV video accelerator imatsimikiziridwa ndi firmware yodzaza mu GPU, yomwe imaphatikizapo magwiridwe antchito ambiri, mwachitsanzo, kuthandizira kwa OpenGL ES kumayendetsedwa kumbali ya firmware. Kwenikweni, kumbali ya GPU, mawonekedwe a makina ogwiritsira ntchito amachitidwa, ndipo ntchito ya madalaivala otseguka imachepetsedwa kukhala mafoni owulutsa ku firmware yotsekedwa. Kuti athetse kufunikira kotsitsa ma blobs, kuyambira 2017 anthu ammudzi akhala akupanga pulojekiti yopanga mtundu waulere wa firmware, kuphatikiza zida zogwirira ntchito kumbali ya VC4 GPU.
