1. Connecting the Gen4-Lcd-Cape

7. Once power is connected, something should be displayed on the gen4-

4DCAPE a few moments after it has started to boot. Each distribution

will behave differently and might require different input from the User

(It is recommended to have a keyboard attached while setting the

system up, as login details etc. may be required). Some distributions may

prompt for LCD calibration during the first boot, while others may

prompt for Username/Password.

gen4-4DCAPE Troubleshooting

For older versions of the BeagleBone Boards, the eMMCs of these boards

might have an outdated version of the U-boot which will not load with the

gen4-4DCAPE properly.

To know the bootloader version and if it is applicable to be used with the

gen4-4DCAPE, run the following code:

$ sudo /opt/scripts/tools/version.sh | grep bootloader

Check the versions of "microSD" and "eMMC". To work properly, the

"microSD" version must be older than the "eMMC" version and it must be

greater than 2018.03.

To fix this, remove the version of U-boot from the eMMC. An example is

clearing the 10Mb of the drive:

$ sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10
