Customizing boot phase

[paolosantini]

Two questions:
1) my Variscite dart-6ul board shows three different images during boot phase: an initial splash screen (placed in rootfs/boot/ folder), a MyImage_clut224.ppm stored in Kernel, and a last image before to start all apps placed in rc.local for autostart. Where is placed this last image and how can I customize it?
2) after boot phase I edit rc.local file to start automatically my app: this starts after a Linux terminal that appears on my lcd display before my app. How can I do to start my app immediately, with no Linux terminal visualization?

Thanks gusarambula, related to various images appearing during booting phase (probably in order to avoid the user could see text line or blank  LCD display during starting phase), I see three different images:

- the first is in u-boot phase: a "bmp" graphic file placed in boot folder in file system. I solved this placing my own image;

- second image is in kernel: a bit complex because it requires a passage from ".ppm" format in ".c", edit Kconfig and so on, but also these steps are done and I solved, placing my second onw image;

- third image I see during startin phase I don't know where it is placed and how to replace it.

Enclosed video could explain better my problem: first is VARISCITE logo, second is Linux Penguin in the top left side, third is VARISCITE YOCTO PROJECT with blue progress bar. My main problem is this last third image.

Any suggestion?

Hello Paolo Santini,

I would recommend contacting the board manufacturer for information on how to customize this board BSP.

There are a couple of threads on the communities that may also help which although not specifically for this board in particular (thankfully your board BSP is provided through Yocto, so should be very similar), like the following thread:
