As described by [1], the kernel generated by the configuration for the STM32f469 Discovery board is buggy. Using a newer kernel, as suggested by [1], increases the dtb and Kernel image size. In particular, the 5.12 version of the kernel generates a dtb and a kernel image whose sum exceeds the 2 MByte of the flash module. So I decided to replace the afboot-stm32 bootloader in the flash with U-boot to easily boot the system from sdcard without having to worry about the size of dtb, kernel and rootfs generated by the configuration. This solution allows you to fix the kernel boot issue and makes it possible to use its future versions.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
