when I increase this variable (to 16MB bar size) it just breaks litepcie_util info and dmesg also reports ffffffffffffffffffffffffffffff for the device name or whatever. The bar size reported by sysfs remains 1MB, and the device is unusable. For a while I thought something was wrong with my programming procedure but it turns out that once I lower it back to 1MB everything's happy

It connects to the global "SoC" address space basically.
<sajattack>
at what address offset?
<tnt>
I use something like self.bus.add_slave(name="radio", slave=mybus, region=SoCRegion(origin=0xf0040000, size=0x40000, cached=False)) to connect a custom wishbone peripheral to part of it.
<tnt>
I think it starts at 0xf0000000

thanks

my goal right now is to display a single colour other than black or white on my framebuffer. time to figure out wishbone
