v2020.04.0-Toolchain.Only

1088c4d

April 2020 Tools Release - Toolchain Only

Binutils 2.32 with SiFive CLIC patches
GCC 8.3.0 with SiFive CLIC patches
GDB 8.3.0 from FSF 8.3.0 release
Newlib 3.1.0 from SiFive branch

Highlights:

GCC toolchain adds support for additional multilib builds as well as support for externally supplied c libraries. --arch=rv32imfc is now enabled to support the “c” part of the arch specification. This configuration was not previously released. Support for alternative C libraries GCC is made possible by unzipping the library into a specific directory and linking with the --spec flag for the appropriate library. Pico lib is available on Github and a size optimized lib available from SCD upon customer request. There is also a fix for the newlib math library to expose the previously hidden symbol __math_oflowf. Finally there is a binutils update to support SiFive custom instructions CLFUSH.D.L1 and CDISCARD.D.L1 to ease disassembly and debug views. GDB is also available in a version with python3 support enabled (python3 is also bundled).

v2020.04.0-Non.Toolchain

6b19ff1

April 2020 Tools Release - Non Toolchain

OpenOCD 0.10.0 (latest) from RISCV repo
QEMU 4.2.0 from qemu.org 4.2.0 branch
Trace-Decoder from SiFive branch
DTC from dgibson github branch
Spike-DASM from RISCV repo
XC3SPROG from SiFive branch

Highlights:

Spike dasm utility is built as part of the Freedom Tools sdk-utilities package. The spike dasm utility is a stream parser that interprets the opcode output of the spike simulation and converts it into human readable RISC-V instructions.
Trace-Decoder adds multi-core support. Primarily consumed by Freedom Studio, this command line utility is used to reconstruct a Nexus 5001 trace into a human readable format that can be used for debugging and performance analysis.
OpenOCD
- BSCAN tunnel support (passes riscv-tests against Arty)
- Properly support large flash devices
- Add support for 64bit memory reads/writes
- A warning is displayed if “-rtos riscv” is used in a config script.
- Merge upstream changes as of change 31a3324b (#411)
- Improved system bus write performance (#405)
- Combine SMP group registers into one list for gdb (#417)
- Add support for 64-bit memory reads/writes using program buffer (#419)
- Warn about using -rtos riscv. (#430) Use -rtos hwthread instead. In January -rtos riscv will be completely removed.
- Properly support large flash devices with fespi controller (#421)
- Increase maximum number of harts (#429)
- Translate virtual address to physical address if address translation is enabled. (#425)
- Add preliminary support for vector register access (#448)
- Update to 1.11 privileged spec. (#455)
- And now with --enable-remote-bitbang and --enable-jtag_vpi. Allows to connect to the spike simulator
- And a lot of other updates.
Updated to QEMU v4.2.0 upstream with modified sifive_u machine, so that it still works with freedom-e-sdk qemu u54 and u54mc bsp's. Now 4.2 version of QEMU works with E SDK.
