Technical difficulties

Hi All,

 So I'm having a few small technical difficulties here, I want to post some better pictures of the tablets and some movies of Java SE and JavaFX running on the tablets, we have a 2MB upload limit on the blog site, so I'm having to find ways of dealing with this.

 Basically Tom knows now how to build a Linux for a stock tablet we can buy of the web, it's been much easier with Marvell, Freescale and FIC helping us with techniques and drivers.

Touchscreen has cause Tom a lot of grief but we have single touch under control now.

Getting a wifi network manager caused him fits, but that is fixed also.

If someone wants to build a commercial tablet  just for Java, basing it on Linux and SE-E looks like feasible option.

Have been playing with Ubuntu and it seems to be a good option.

We are trying to pick what sort of ARM processor we want, single or dual core to start.

Screen size, I'm leaning to 1280 x 1024 to start.

What size nand to put inside 8Gb or 16Gb, what ports we want, USB, HDMI, do we want a 3G chip, which means we need a sim card slot.

Though all of these decisions always come back to price point.

In terms of hardware, there are several vendors who provide designs that can be used to build such a tablet.

More later

Freescale i.MX5x ARM tablet from FIC

Hi All,

 So here are some pictures of the Freescale i.MX5x powered FIC tablet running our Linux (Open Embedded), XFCE desktop Java SE Embedded for ARM and Tom's JavaFX 2 build.

FIC is a Freescale partner that built this tablet for a Brazilian customer.

 My next task is to see if I can get the Canonical Ubuntu (Linaro) build for i.MX53 to boot on this device with the Unity desktop.

I do have the Canonical build running on a i.MX6 quad core developer platform, so I'm hopeful the i.MX53 build will work on the tablet.

More to come, like what would you want as hardware for a Java tablet ?

Who thinks a Linux ARM tablet with Java SE and JavaFX is a good idea ?

Hi All,

So it's been awhile since I blogged, I've been busy with my colleague Tom Karbowski  investigating the whole world of ARM, Linux and tablets.

Well because of the great work by Tom we now have a three tablets that don't run Android anymore.

We have a Freescale, Nvidia Tegra 2 and Marvell powered tablets that run our version of Open Embedded Linux, they both run Java SE Embedded for ARM fine.

Tom took the JavaFX code for Linux and cross compiled it for ARM.

We still need to deal with power management of the tablet, but Tom has got most of the hardware working, touchscreen, wifi, USB, ethernet.

Our plan is to work with Canonical (Ubuntu) to replace our Open Embedded as we are the Java Guys not Linux guys, I'm going to try a Canonical Linora build for the i.MX53 on the Freescale tablet next week, this will get use the Unity desktop instead of the XFCE we currently have.

We will be demoing most of this at The Freescale Technology Forum show in San Antonio Texas the week of June 18th, Oracle is a Gold sponsor of this event, so if your in the area come and see us at the show.

I'll be blogging more about building a commercially available Linux tablet as we go through the process.
