From 1a1239fd286ec5602e6ea29a1799e26b6254202f Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Sun, 23 Apr 2023 19:08:20 +0200 Subject: [PATCH] configs/stm32f769_disco_sd_defconfig: new defconfig Board support package includes the following components: - mainline Linux kernel 5.15.108 - mainline U-Boot 2023.04 - default packages from buildroot Note: There is a problem in u-boot display management. It should display the ST microelectronics logo but "noise" is displayed (like when running the command dd if=/dev/urandom of=/dev/fb0 in Linux). I also tried to change version (even the first version in which this feature was introduced), but without success. Despite this I decided not to disable the video management configuration to remind us that it needs to be fixed :).
