Hi, Sorry, I did not set a message subject in my previous email. Ping on this patch. I built all of the riscv/riscv BSPs that use it. It works for the generic riscv/qemu BSP, the PolarFire BSP, and the RISC-V BSP I am working on where the macro failed. https://lists.rtems.org/pipermail/devel/2022-September/073390.html Thanks, Alan
