Using a smaller size (256x192), I don't get out of memory issues, but things blow up when I try to launch the display: ``` sysbus WriteDoubleWord 0xf000301c 256 sysbus WriteDoubleWord...

Here's a suitable binary -- it just prints to the serial port and spins forever. Start it and then poke the framebuffer registers from the monitor as described and boom....

I also verified that the same error occurs if the program writes to the vfb registers instead of doing it from the monitor.

I was not aware such a configuration existed (Litex as I've used it on ULX3S accepts 32bit writes to registers without an issue). Is this a configuration option somewhere in...

Yeah, ideally Renode's peripherals would match the behaviour of the FPGA peripherals. UART, Timer, and Framebuffer are the most immediately useful. I'll have to see how involved building Renode from...
