The latest u-boot uses gpio commands to turn on the HDMI power, but not the 4 USB power domains. This might be the cause of the bug. Either USB is also turned on with GPIO commands or better yet, none of the domains are turned on by GPIO commands.
This looks like it was an artifact of old code being used on RC1. RC2 does not appear to have any problems with this. Reopen if it turns out to be an issue later.
This is still a problem with v3.0.3.
This is not an issue with the Waveshare display. It could be a Manga Screen issue.
This does not seem to be a software issue. Can be revisited again if it comes up.
A setup with Recore A6 and Manga Screen 2 small sometimes causes the screen to not turn on. This looks to be a race condition and might be fixed with enabling the USB power before the HDMI output.
