Jan 09, 2019 · Linux Support: ===== Although U-Boot should support any OS or standalone application easily, the main focus has always been on Linux during the design of U-Boot. U-Boot includes many features that so far have been part of some special "boot loader" code within the Linux kernel.

"The screen goes black after u-boot."-- Probably because the MMU is being enabled. You would have to ensure U-Boot allocated its framebuffer in a reserved section of physical memory that persisted through the initialization of virtual memory. " I want to fully disable the kernel from updating the framebuffer/display."

To show how U-Boot can be easily customized, we created a simple practical example where U-Boot changes the U-Boot splash screen when the module starts to update. Create a PNG image in GIMP and convert to BMP as explained above. Store the image into a USB flash drive, SD Card or TFTP server, in our case, the BMP file was stored on a TFTP server.

Apr 14, 2016 · Interrupt u-boot and run the u-boot commands below. In the u-boot just built, the environment variable uboot_defconfig is defined to show which defconfig was used in the build process. Unless you’re already on a 2015.07 or later u-boot, you won’t have this yet, so for the 1st upgrade you need to set it manually.

Jun 02, 2011 · I have the total boot time to about 10 seconds, but there are some intrinsic delay overheads in the X-Load and U-Boot steps (such as copying the Kernel from NAND and decompressing). I know there is reference software in U-Boot for Atmel's AT91 framebuffer, but it seems much simpler than the OMAP framebuffer.

The framebuffer's original function is as a video RAM cache to allow more flexibility to (older) video cards.Many newer cards come with framebuffers on board, which are often already compatible with many operating systems. Enabling framebuffer support in the Linux kernel will often cause graphical artifacts or black screen displays.
