Hello,

I'm trying to access a memory-mapped peripheral on the exynos5422 (ODROID XU4). I have the physical address of the peripheral's registers from the exynos5422 data sheet. As per the Camkes manual, I've used the seL4HardwareMMIO connection type to facilitate this. However, while I can use the excess bytes of the "dataport Buf" as expected, there is a data fault when I try to read from the peripheral's memory-mapped (and readable) registers:

"""

FAULT HANDLER: data fault from test_component.test_component_0_control (ID 0x1) on address 0, pc = 0x3250c, fsr = 0x211

"""

Besides defining the hardware component and this connection in Camkes, is there anything else I must do? I will appreciate any guidance on this matter.

Best,

Michael Neises
