[U-Boot] U-Boot RPI bmp display isn't visible

[Christian Nienhaus]

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)

1152054 bytes read in 50 ms (22 MiB/s)
U-Boot> bmp display $kernel_addr_r || echo error
U-Boot>
```

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
