[seL4] Re: Untyped tutorial on RISC-V

Hi Miriam, What platform are you targeting on RISC-V? I was able to get the tutorial working when doing `./init —tut untyped —solution` and targeting the Spike platform. `seL4_Untyped_Retype` is not architecture dependent, so should work on RISC-V. Ivan

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:

<> main@main.c: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.
