I'm currently testing U-boot 2017.07 on Raspberry Pi, both on a Model B+ and a Raspberry Pi 3. On both devices I'm seeing two issues with u-boot:
* U-boot can't boot the Linux kernel, it just hangs at "Starting kernel ...".
* U-boot doesn't recognise any input via a USB keyboard.
These issues were not present in U-boot 2017.05. I see them both when building U-boot via OpenEmbedded and when building using arm-linux-gnueabi-gcc on Debian Stretch (GCC 6.3.0).
After bisecting to identify the commits which introduced these issues, I've found I can get a working U-boot by doing the following:
* Start with U-boot 2017.07
* Revert "dm: arm: rpi: Move to driver model for USB" (25085236)
* Revert "dm: arm: rpi: Use driver model for Ethernet" (d90385be)
* Revert "dm: arm: rpi: Drop CONFIG_OF_EMBED" (25877d4e)
* Drop CONFIG_USB_STORAGE as leaving this enables gives a compile error when CONFIG_DM_USB is not set.
I've staged these changes here for testing: https://gitlab.com/toganlabs/u-boot/commits/pbarker/rpi
Reverting these commits is definitely a step backwards though so I'm hoping for another solution. Has anyone else has seen these issues and got any ideas? Or has anyone else got U-boot 2017.07 working on the Raspberry Pi?
Please let me know if you need any more details.
Thanks,
