Hello, I have developed an Ethernet application using CAmkES 2.2 and seL4 3.2. Because we are going to open-source the design and other documentation, I thought it would be a good idea to upgrade to the latest version of seL4 and CAmkES. I can pull the latest kernel and merge the compatible libraries with my changes and get everything to compile; however, when I load it on the board it fails... Failed to find any untyped capable of creating an object at address 0x20c4000 Failed to find a way to map address 0x20c4000 Failed to find any untyped capable of creating an object at address 0x20c8000 Failed to find a way to map address 0x20c8000 Failed to find any untyped capable of creating an object at address 0x20e0000 Failed to find a way to map address 0x20e0000 Failed to find any untyped capable of creating an object at address 0x21bc000 Failed to find a way to map address 0x21bc000 Here is my CAmkES configuration which sets up the Ethdrivers cnode and untypes. Keep in mind this works with seL4 3.2 ethdriver.simple = true; ethdriver.cnode_size_bits = 12; ethdriver.simple_untyped20_pool = 4; ethdriver.heap_size = 0; ethdriver.mmios = "0x02188000:0x4000:12, 0x021BC000:0x4000:12, 0x020E0000:0x4000:12, 0x020A4000:0x4000:12, 0x020B0000:0x4000:12, 0x020C4000:0x4000:12, 0x020C8000:0x1000:12"; Can anyone see the problem? Thanks, Chris Guikema
