I am trying to use the latest version of Ubuntu on Raspberry PI 3B+. When GrovePi is connected, the board doesn't boot, instead return to U-Boot prompt. Without the GrovePi shield, board boots up without any issue. It is possible to connect GrovePi after boot for use, but cannot do a hard-boot with the GrovePi connected.
I have updated the boot config to enable I2C as GrovePi communicates with the Raspberry PI via I2C.
Are there more changes required in boot config to get this setup working?
Here are the source of the images that I have used:
Ubuntu 19.04 - http://cdimage.ubuntu.com/ubuntu/releas ... pi3.img.xz
Ubuntu 18.04 - https://wiki.ubuntu.com/ARM/RaspberryPi ... pi3.img.xz
