FPGA toolchain

As of 2018.06.06. this is mainstreamed into ports with commits:
rP471841 - icestorm
rP471842 - arachne-pnr
rP471844 - yosys
rP471846 - examples hx1k
rP471847 - examples hx8k
rP471848 - lattice iCE40 tools

So, now on FreeBSD the open source FPGA toolchain can be installed as standard FreeBSD program from ports:
cd /usr/ports/devel/lattice-ice40-tools && make install clean
or you can use prebuilt version:
pkg install lattice-ice40-tools

Misc

UrJTAG

• updated to 2017.10.

htop

• add vim-like keybindings (hjkl, Ctrl-B/F, g/G)

arm-none-eabi-gdb

• add python support

RISCV-32 MCU support

2019.12

riscv32-openocd

• packaged version of OpenOCD from riscv-mcu
• includes scripts for GD32VF103 board and Sipeed RV JTAG debugger
• Usage:
  riscv32-openocd -f interface/ftdi/sipeed-rv-debugger.cfg -f board/gd32vf103.cfg -c "adapter_khz 1000; init; halt; flash protect 0 0 last off;"

riscv32-none-eabi-gdb

• GDB 8.3 based
• compiled with --target=riscv32
• with python support/files/scripts
• Usage:
  set arch riscv:rv32
target remote localhost:3333
program build/main.elf
load
continue

FreeCAD 0.19

• version 2020.07.07 ed1467ce7572da529bfe42200287347058eaed52
• compiling time: around 2:00 on i7-3520M 2.9 GHz (idle priority, 4 threads)
• assembly2 workbench is disabled, can't be built (tried 0.18 and 0.19 versions). Assembly4 is a python module for FreeCAD 0.19 which can be downloaded and used instead.
• while compiling there are many warnings (which cannot be fixed with adding -DCMAKE_CXX_STANDARD="17" -DCMAKE_C_FLAGS="-std=c++17" to CMAKE_ARGS):
  warning: use of the 'nodiscard' attribute is a C++17 extension [-Wc++17-extensions]

Learned

• make install will install only files (from stage/) which are specified in pkg-plist

How to use GitHub project with submodules:

riscv32-openocd as example

• make extract and find exact hash of submodules:
  USE_GITHUB= yes
GH_TUPLE= riscv-mcu:riscv-openocd:9e6a7a2e5320cdaeeafcc79debedfd216f443f19 \
msteveb:jimtcl:0.77:jimtcl \
syntacore:libjaylink:0.1.0-17-g4959f4e:libjaylink
• OpenOCD will use in-tree submodules if (empty or non empty) folders are found:
  @${RMDIR} ${WRKSRC}/jimtcl
@${RMDIR} ${WRKSRC}/src/jtag/drivers/libjaylink

Creating/updating pkg-plist:

make makeplist

• check it manually
• remove line: 'you/have/to/check/what/makeplist/gives/you'

problem: after editing pkg-plist make install won't apply changes, fix:
rm work/.PLIST.mktmp
