CONFIDENTIAL23

Creating better ARM hardware [ for IoT ]

Better is an a misleading word.

It will always be possible to make bad hardware

The key is to enable a diverse ecosystem of developers to be more productive

The mbed HDKis designed to help this

Fragmentation is the real competition, or even enemy

Collaborative consolidation of technology, products and services

Black-boxing and abstracting is the way forward

CONFIDENTIAL24

Fragmentation - The “F” word

Fragmentation is an issue for commodity technology

Debug probe poviding USB to JTAG/SWD bridge

Enough already!

CONFIDENTIAL25

CMSIS-DAP

Invented as a standard way of exposing the Coresight DAP instruction set

Its non-proprietary, its just the DAP instruction set! Commoditises everything between the SWD connector and the host debug

driver

First implementation was over USB, but the transport could be anything

Exposed as a USB HID end point

Debug/programming can now be done in any tool/language that can bind to USB HID

Custom tools, custom debug scripts – the power is in the hands of the developer

CONFIDENTIAL26

Flash Algorithms – (A personal pet hate!)

The complexity of the flash algorithm is in the debug host

Flash algo and routines downloaded to SRAM and executed The hard-to-debug algo work is replicated over and over

The debug host shouldn’t care about the algorithm – No one should care!

Silicon partner should provide algorithm in on-chip ROM, or standard flash location

Standard API, called through DAP

A long term goal..

Rant

Off - Topic

CONFIDENTIAL27

Hardware libraries

Component tree sourcing remains a barrier at low volume, just to get something made

At higher volume optimisation makes sense

At very high volume, it will be done for you!

Seeedstudios Open Parts Library is and an interesting initiative I see a lot of value in

(80% of the tree is already there!)

A kit exists!

CONFIDENTIAL28

Software best practices

I’ll not talk about this too much

See Bogdans presentation for more details 12:00, Firmware Sala

Initiatives around Test Driven Development and Unit Testing

Get developers thinking about test at the start, especially if their goal is production

CONFIDENTIAL29

Hardware best practices

Seeedstudio spend 2-4 weeks per 3rd party project developing the test software and jig

Test only considered at the production hand off

Hardware respins common

Test software written from scratch

mbed HDK – Pulling it all together

CONFIDENTIAL31

mbed HDK Pulling it all together – Debug interface

A series of debug interface reference implementations at schematic level

Includes CMSIS-DAP support

Includes Drag and Drop, USB UART

Implementations with each silicon partner

Built in alignment with OPL

Includes board level test hooks

CONFIDENTIAL32

mbed HDK Pulling it all together – Components

Component vendors and partners add components

Composable subsystems (complete, with passives etc)

Critical layout as needed

Built in alignment with OPL

Includes board level test hooks

Component software for HDK implementation

CONFIDENTIAL33

mbed HDK Pulling it all together – debug interface

CMSIS-DAP

…Roadmap

Debug interface source under Apache 2.0

Specification maintained by Keil

Includes flash algorithms

Exciting new features

Debug interface source builds for specific HDK

implementations (not examples!)

CONFIDENTIAL34

mbed HDK Pulling it all together – The future

All speculation at this stage, but I believe that :

The HDK can be extended to offer features to smooth the transition to production

There is work to do on new EDA/CAD tool flows

For IoT, communication modules will become the focus

80% of the resourcesComplex design (hardware and software)Complex and expensive qualificationsHDK will start to include mbed enabled, qualified modules soon!
