WORKING
TOGETHER
IoT Toolchain BoF
We are here to
● Ask questions about IoT development
● Find out what tools need customization
● Find out what new tools are needed
Goal for today
● Chat, give opinions
Goal for later
● Simplify IoT development

Things I don’t know about
? Is IoT Toolchain the same as Embedded Toolchain ?
? What tools do IoT developers need ?
? Are current tools enough for IoT development ?

IoT toolchain ?= Embedded Toolchain
● IoT has a gateway side with reach OS
○ Embedded doesn’t
● Embedded development depends on JTAG
○ Does IoT depend on JTAG?
● IoT is similarly sensitive to code size

6. ENGINEERS AND DEVICES
WORKING TOGETHER
A day of IoT developer?
● Code
● Build
○ Compilers, assemblers, linkers, libraries
● Test
○ Can testing using hardware scale?
○ Can emulation test WiFi, Bluetooth, motion and other real-world artifacts?
● Debug / Analyze
○ Does IoT developer need a classical debugger?
○ Does IoT developer need a good tracer / logger?
○ Which tool is used most?

WORKING
TOGETHER
Linaro’s bare-metal toolchain today
● Not an embedded toolchain
● GNU-based
○ GCC, Binutils, Newlib, GDB
● A-profile
○ No libraries for M- or R-profiles

8. ENGINEERS
AND DEVICES
WORKING
TOGETHER
ARM’s embedded toolchain today
● Good embedded toolchain
● GNU-based
○ GCC, Binutils, Newlib, GDB
● M-profile
○ Cortex-M0 -- Cortex-M7
● R-profile
○ CortexR4 -- Cortex-R8
