Hello community,
thank you for providing such a good software. I hope this is the right way to get help.
I successfully run my RPI3b with u-boot and buildroot. I have attached the official 7“ touch display for the rpi. Which also works fine in linux.
When I want to display a bmp on the display in u-boot nothing is displayed and no error is shown.
The following is the output on the serial console and also on the display:
``` U-Boot 2018.07 (Aug 20 2018 - 17:00:45 +0200)
DRAM: 768 MiB RPI 3 Model B (0xa02082) MMC: mmc@7e202000: 0, sdhci@7e300000: 1 Loading Environment from FAT... OK In: serial Out: vidconsole Err: vidconsole Net: No ethernet found. starting USB...

The console output and also lcdputs works on the display, but bmp display does nothing and don’t print error.
This is my u-boot defconfig:
``` CONFIG_ARM=y CONFIG_ARCH_BCM283X=y CONFIG_SYS_TEXT_BASE=0x00008000 CONFIG_TARGET_RPI_3_32B=y CONFIG_SYS_MALLOC_F_LEN=0x2000 CONFIG_DEFAULT_DEVICE_TREE="bcm2837-rpi-3-b" CONFIG_DISTRO_DEFAULTS=y CONFIG_OF_BOARD_SETUP=y CONFIG_LOGLEVEL=7 # CONFIG_DISPLAY_CPUINFO is not set # CONFIG_DISPLAY_BOARDINFO is not set CONFIG_SYS_PROMPT="U-Boot> " # CONFIG_CMD_FLASH is not set CONFIG_CMD_GPIO=y CONFIG_CMD_MMC=y CONFIG_CMD_USB=y CONFIG_CMD_BMP=y CONFIG_OF_EMBED=y CONFIG_ENV_FAT_INTERFACE="mmc" CONFIG_ENV_FAT_DEVICE_AND_PART="0:1" CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG=y CONFIG_BOOTCOUNT_LIMIT=y CONFIG_BOOTCOUNT_ENV=y CONFIG_DM_KEYBOARD=y CONFIG_DM_MMC=y CONFIG_MMC_SDHCI=y CONFIG_MMC_SDHCI_BCM2835=y CONFIG_PHYLIB=y CONFIG_DM_ETH=y CONFIG_PINCTRL=y # CONFIG_PINCTRL_GENERIC is not set # CONFIG_REQUIRE_SERIAL_CONSOLE is not set CONFIG_USB=y CONFIG_DM_USB=y CONFIG_USB_DWC2=y CONFIG_USB_STORAGE=y CONFIG_USB_KEYBOARD=y CONFIG_USB_HOST_ETHER=y CONFIG_USB_ETHER_LAN78XX=y CONFIG_USB_ETHER_SMSC95XX=y CONFIG_DM_VIDEO=y CONFIG_SYS_WHITE_ON_BLACK=y CONFIG_CONSOLE_SCROLL_LINES=10 CONFIG_PHYS_TO_BUS=y CONFIG_OF_LIBFDT_OVERLAY=y ```
