GCC RISCV for Pico toolchain version 15.1 released

Jan Cumps

This is a bit of a surprise. Raspberry released a GCC 15.1 version of their Pico RISCV toolchain. That's a more recent version than the current (at the time of writing, 14.2) version of the mainstream ARM toolchain.

If you are using the VSCode Pico extension, select RISCV_ZCB_RPI_2_1_1_3. It 'll install the toolchain for you.

note: I wish they 'd use the GCC version numbering

  • This is a really good version of GCC. The RISC release doesn't have all the goodies, but it supports most of the good stuff of C++ 26

    And a lot of that good stuff is for embedded designs. Really efficient STL.
    I 've done a set of posts that showed where the machine level cost of using STL was 0 ticks 0 bytes.
