Wondering if anyone has noticed an issue using the RPi Framebuffer from bare metal with very recent versions of the firmware?
Using code that is known to work on both Pi1 and 2, if I use firmware downloaded this week all I see is a black screen. Debugging via blinking LED shows that all the calls to the mailbox are succeeding but nothing ever shows on screen.
If I take the same kernel7.img and use firmware from Feb or April 2015 then everything works just fine.
Has anyone else come across this?
