About Me

Almost Still Call me ‘Core Contributor for OpenSolaris’ but please call me a ‘Japanese Evangelist for Raspberry Pi :)’Now Reading Japanese Raspberry Pi Users Group and help as a Official Mod for Raspberry Pi forum for Raspberry Pi Foundation to maintain the ‘Japanese Category’

Last year at foundation

4


At BBC in London..

5


Visiting..

6


Interviewed at BBC Click

Innovation is Great

Agenda

• What happen on Raspberry Pi foundation

• Background of Releasing Raspberry Pi 2• How to use Raspberry Pi 2• Roadmap? and New releasing Products.

What happend on Foundation

Japanese Raspberry Pi Users Group at Linuxcon 2015

10


Broadcom-Layoff• Broadcom Cuts 2,500 Jobs as It Winds Down

Baseband Unit- http://reut.rs/1I546ip- But they continue to release Raspberry

Pi SoC(BCM2835）

- Team of BCM2835 has been merged another team to restructure their business

11


Decide to visit Foundation• I discussed some of community members to the future

of Raspberry Pi toward the restructuring of Broadcom- Eben told us ‘not huge changes in Raspberry Pi specs

and features’.but they might be sooner changed their mind because of broadcom restructuring

- The foundation still is run by a few members,but selling over 3 million..how they will do that?are they okay?

- The lifecycle of ARM SoC is very short..they might abandon using ARM11(2835)

12


Go to ‘Pi Tower’ in Cambridge

13


Eben recommend New A+

14


Where is ‘Pi Tower’….

15


about Raspberry Pi A+• competitive price - set 20US$

- http://bit.ly/1zH9tjb- Smaller,thin- lower power consumption- beat Koreans ‘Compatible machines’ Odroid W

- Raspberry Pi Foundation had a legal issue with them

- my Odroid W is very easy to break..16


Odroid issues..

17


About their Office • Arrived the morning there are a few people

working - mainly evaluate their products• After the lunch some people gathering there to

help the Foundation - mainly Univ. Students there in Cambridge

• There are some use cases putting on each meeting rooms.

• Very impressed ton of the ideas using Raspberry Pi from the children all over the world.

18


Foundation members • Almost is the engineers from Broadcom• Univ. Students (Cambridge?) helping the Foundation • but there are many teachers (almost is teaching

programing at schools) joining the Foundation to improve and add values to Raspberry Pi • They discussed the promotion plans for

Education ‘all the day’ - from early morning to late night

Sudden Announcement • Sudden Announcement at the end of Jan • Almost mod were surprised..

- why using A7 Chips - is the same as Chinese Banana Pi or some ‘abuse’ compatible machines?

- it can work on old A(+)/B(+) images?- apps on old A(+)/B(+) can works on it?- OSes(like Raspbian) is ready for it? they can catch

up with it?- Ubuntu can work on it?

Sudden Release..

• Before releasing Raspberry Pi main OS Raspbian was RC..GA?

• Running New Pi updating to fix it..• Xenon Death Flash issue(covering U16 to fix)

• official notice:http://bit.ly/1M6NKVi• how to reboot with Xenon:http://bit.ly/

1K6IDFq• how to fix the issue:http://bit.ly/1HIddAn

Let’s try flash crashing:)

Moving from RPi 1 Model B+

30

• because of changing CPU architecture,you cant use your microSD now using on your Raspberry B(+)/A(+) just out of the box.- Raspberry Pi B(+)/A(+) - armhf (hard-float)- Raspberry Pi 2 - armel(soft-float)

- thus 6x faster but 4 Core CPUs• if you use your own SD for RPi 1 and it is made by

‘dd’ (not NOOBS) ‘use upgrade’ command# apt-get update# apt-get dist-upgrade


Moving from RPi 1 Model B+

31

• if you made your own SD for RPi 1 with NOOBS please make sure before updating - Copy your own SD except ‘os’ directory

and recovery.cmdline• latest image has two kernels kernel.img

(armhf) and kernel7.img(armel)


Roadmap of Raspberry Pi

32

• First they’re planning to fix Xenon flash issue :)• Mainly produce RPi 2 B and RPi A+• A+ is for Robot or Electric DIY.• B+ price is down! but ‘focus-off’

• perhaps getting less production than 2 and A+

• improve stably - down compatible• use your image with both old Pi and New Pi


Roadmap of Raspberry Pi

33

• Increasing Equipments and Apps and very easy to use• Not compiling Kernel - most of them

already are included RPi Kernel (USB DAC,Hats..)

• Increasing Solutions for Education • much more meetings for promotion plans

for Education at Raspberry Pi Foundation


New Product for RPi

(Appendix) RPi on Jessie?

• Now Raspbian has Jessie repo you can upgrade Jessie - /etc/apt/source.list

• it very loong time to update…• but some of apps hasn’t improved yet so

you should use stable wheezy when using some apps on RPi

summary• Raspberry Pi 2 suddenly released..(perhaps)

because of CPU issue• First time a bit confused because Eben do not like

‘abuse’ compatible machine like Banana Pi and Orange Pi

• Pi 2 is compatible with Pi A(+)/B(+) but please note Pi 2 is armel and some of apps need to fix for new Pi

• Next Gen Pi(?) might be improved stably…44
