Hi Arun, 


32-bit RISC-V is not scheduled on our roadmap currently, unless it's required for another project.


Code for 32-bit RISC-V is there for the kernel and user-level, and currently compiles. But the 

kernel doesn't successfully boot and needs investigation. A community contribution is welcome :).


Thanks

Anna.

Congrats on the new release! I'm very excited to see upstream support for RISC-V.

Out of curiosity, is there a timeline for 32-bit RISC-V support?

Thanks,
Arun

We are pleased to announce initial RISC-V support for the UC Berkeley Spike simulator platform.

# seL4 Version 9.0.1 Release
 Announcing the release of `seL4 9.0.1` with the following changes:

9.0.1 2018-04-18: BINARY COMPATIBLE

## Changes
 * On 64-bit architectures, the `label` field of `seL4_MessageInfo` is now 52 bits wide. User-level programs
   which use any of the following functions may break, if the program relies on these functions to mask the
   `label` field to the previous width of 20 bits.
     - `seL4_MessageInfo_new`
     - `seL4_MessageInfo_get_label`
     - `seL4_MessageInfo_set_label`
 * Initial prototype RISC-V architecture port. This port currently only supports running in 64-bit mode without FPU or
   or multicore support on the Spike simulation platform. There is *no verification* for this platform.
