Hi,
I would like to change the bitmap of the U-Boot Bootloader at startup of my Panel-Card. The default bitmap is a blue flower and I want to show an own bitmap refering to our company. I don't know wheather it makes any differences, but I'm using Windows Embedded CE 6.0 on the Panel-Card. Is there any step by step how-to or could someone explain me how to do this? I'm very new to all this stuff...
Thanks!
Re: changing U-Boot Bitmap at startup (Panel-Card)
Have a look at this how-to on this site:
http://www.armbedded.eu/node/44
It explains how to implement your own boot-logo for Panel-Card35. In regard to u-boot, it makes no difference, if you use Linux or WinCE.
Re: changing U-Boot Bitmap at startup (Panel-Card)
Thanks a lot so far! I do not have any Linux OS to run the described arm-softfloat-linux-gcc. Is there any Windows version of it or a compiler I can use alternatively under Windows (XP)?
Re: changing U-Boot Bitmap at startup (Panel-Card)
There are compilers for Windows, but that would be not sufficient as you need the complete Linux tools for development such as make for compiling u-boot.
Do you have the possibility to install Linux in a VM on your computer? Otherwise we can also do that for you against a little fee.
Re: changing U-Boot Bitmap at startup (Panel-Card)
Ok thanks. I think I will install linux in a VM or maybe I get the compiler running with a Knopix live CD.
In a similar thrad I read, that the new image must be in a 256 RGB color mode but what width and height should the image have? I use the Panel-Card with a 3,5" Display.
Re: changing U-Boot Bitmap at startup (Panel-Card)
The display has a resolution of 320 by 240 pixels.
Re: changing U-Boot Bitmap at startup (Panel-Card)
Hello,
I compiled the new image sucessfully under linux. Now I wanted to flash the new bootloader-image and followed the instructions of the Howto "Implementing an own boot-logo for Panel-Card" but the network connection doesn't work. Here the details of my system and configuration:
TFTP-Server
- A TFTP-Server (SolarWinds TFTP-Server) and its service is running under Win XP.
- The new u-boot image is direktly in the root folder C:\TFTP-Root and is named u-boot-logo
Network configuration (Windows-PC)
- IP of my Windows-PC: 192.168.0.2
- Subnetmask of my Window-PC: 255.255.255.0
Configuration of U-Boot on the Panel-Card

Connection
The Panel-Card is connected via crossover cable directly with the PC. The green LED on the Panel-Card is on and the orange LED is blinking while trying to transfer data.
Transfer fails...!

and so on, again and again...
The ping command under Windows also fails with a timeout error.
So there is no working network connection, unattached from the TFTP-Server.
What's the reason?
Re: changing U-Boot Bitmap at startup (Panel-Card)
U-boot does not answer pings. It is the tftp-server or your firewall.
When using windows I would recommend this one, which works fine on our machines:

Re: changing U-Boot Bitmap at startup (Panel-Card)
Thanks a lot.. it works now! The Windows firewall blocked my other TFTP-Server without asking me.
