From 7ebcfe3cb99ba536b5dcce7704956aeb11b6a57b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ga=C3=ABl=20PORTAY?= Date: Tue, 15 Apr 2025 17:31:24 +0200 Subject: [PATCH] board/raspberrypi/readme.txt: add videocore note MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The VideoCore blobs for the Raspberry Pi 1, 2, 3, Zero, Zero W and Zero 2 W are differents from the ones for the Raspberry Pi 4 and the Compute Module 4. The VideoCore blobs for the Raspberry Pi 4 are named with a 4[1] (i.e. start4.elf, start4x.elf, start4db.elf and start4cd.elf). This precises which VideoCore firmware blob files are present on the Raspberry Pi 1, 2, 3, Zero W, Zero 2 W and which files are present on the the Rapsberry Pi 4 and the Compute Module 4. Note: The VideoCore blobs for the Raspberry Pi 5 are self-contained in its bootloader EEPROM[1][2]; there is no additional files for pi5.
