PCM052: u-boot splash screen support

mpfgregory — Tue, 22 Sep 2015 09:07:09 GMT

I have managed to get the u-boot splash screen on my PMC052 working. I just wanted to share in case anybody else would like to use it.

You will need the 2015.04 u-boot from Toradex:

u-boot-toradex.git - U-Boot bootloader for Apalis and Colibri modules

The guys at Toradex have been so kind to port the DCU display driver to u-boot. You only need to add the PCM052 configuration to their u-boot. This can be done by copying the respective files from the vf610twr board. To include the display driver you can copy the respective parts from the colibri-vf board. You can find all necessary changes in the attached patch file.

If you are using yocto, in order to use the toradex u-boot, you need to change the meta-fsl-arm-extra/conf/machine/pcm052.conf:

--- PREFERRED_PROVIDER_u-boot = "u-boot-timesys"

+++ PREFERRED_PROVIDER_u-boot = "u-boot-toradex"

Then just bitbake u-boot.

To add a custom boot logo, add a file pcm052.bmp to git/tools/logos/ in the u-boot work directory.

Of course you can also add the DCU driver to the vf610twr board.

Best regards

Michael
