OPUS devices update manual
You can use these two files in the update process described above now and the boot logo will
be changed to that image. Be aware that you always have to re-create the md5 checksum file
when you change the boot logo image.
There is a second way to change the boot logo directly on one device (quicker for one device,
but not suitable for several devices):
1a . (OPUS A3/A6 G1). Create a png image in the appropriate resolution (A3: 480x272, A6:
800x480)
1b . (OPUS A6G2/A8). Create a bmp image in the appropriate resolution (A6 G2: 800x480,
A8: 1280x800)
1c . (OPUS B3). Create a bmp image in the appropriate resolution (B3: 800x480)
2. Put the image on a FAT32 formatted USB stick
3. Log in to the serial console (see chapter 4.1)
3b. Connect the USB stick to the running device
4. Check that the USB stick is mounted to /disk/usbsda1 by executing the command df
5. Note the path of the USB stick
6 a. (OPUS A3/A6 G1). Write and execute the command:
setbootlogo /disk/u-sbsda1/imagename.png (change "imagename" to the actual name of the
image, and change the USB path if necessary)
6 b. (EGSPRO/EGSCORE devices). To copy the boot logo for the normal start, please use
the following command (<image.bmp> is the path to the image file):
cp <image.bmp> /boot/logo.bmp
To change the recovery boot logo, use this command:
cp <image.bmp> /boot/recovery.bmp
Afterwards, execute the command
sync
