Dear seL4 devs and community, I'm trying to do the seL4-tutorials on a RISC-V architecture. Now I'm stuck on the untyped tutorial. I tried to run the solution of the tutorial but I get the following error:
<<seL4(CPU 0) [decodeUntypedInvocation/128 T0xffffffc17fee7200 "rootserver" @103fc]: Untyped Retype: Destination cap invalid or read-only.>> [email protected]:48 [Cond failed: error != seL4_NoError] Failed to retype seL4 root server abort()ed Debug halt syscall from user thread 0xffffffc17fee7200 "rootserver" halting... I'm calling the function as follows: seL4_Untyped_Retype(parent_untyped, seL4_UntypedObject, // type untyped_size_bits, //size seL4_CapInitThreadCNode, // root 0, // node_index 0, // node_depth child_untyped, // node_offset 1 // num_caps ); parent_untyped = info->untyped.start + i (where i is incremented until (info->untypedList[i].sizeBits >= untyped_size_bits && !info->untypedList[i].isDevice) untyped_size_bits = seL4_TCBBits+1 child_untyped = info->empty.start It seams as if the function is not allowed for RISC-V. I don't know where the problem lies and I would appreciate any help or ideas.
