![]() ARM SBBR (Server Base Boot Requirements) defines SPCR (Serial Port Console Redirection Table) as a mandatory ACPI table that specifies the configuration of a serial console. In the linux kernel, ARM developers have decided that consoles defined by SPCR are always enabled when existing, see e.g.: https://lore.kernel.org/linux-serial/20200430161438.17640-1-alpernebiyasak@gmail.com/T/ Specifying console=ttyAMA0 (which is a serial console) is thus redundant for an ARM SBSA board. (It also blindly assumes that the serial console is on ttyAMA0, which might not be true.) Drop the explicit console=ttyAMA0 on the kernel command line, such that the kernel can pick up the default console defined by SPCR. This is similar to how it is currently done for board/aarch64-efi/grub.cfg. Signed-off-by: Niklas Cassel <niklas.cassel@wdc.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> |

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
