Solder header onto Joggler PATA port

The wiki article :

explains a great deal.

But just to experiment, I thought, what if I just solder a header onto the PATA pads, then I can connect whatever to it. Admittedly there may be issues closing the joggler back up. I'm thinking I can find a better solution to mounting a PATA drive externally, or even just a connector, this way. And I would be able to test and compare a PATA connected drive with applications I'm currently using USB for.

I think I would need a right angle header, but I don't know what the pitch would be ( space between the pins ). Plus this way soldering on and removing with braid should be easy enough ?

Once the header is mounted, I could use 40 wire flat cable with female connector to connect suitable hardware on the drive end.

Comments on the above would be greatly appreciated.

Could anyone comment on how much, if any, of a speed improvement is using a PATA connected drive over a good USB3 thumb drive on the USB port ? Is it possible to boot from a PATA connected drive using the standard BIOS or can the PATA drive only be used once booted and set up from a USB connected drive ?

I have tried this purchasing the ZIF clips for the O2 Joggler and the Openpeak 2 (with front speakers).

Purchasing a hot air gun and tiny tips for my soldering station with large circular lamp with magnifying glass.

Totally destroyed the pads on the Openpeak 2. That said I have left it open for tinkering. Added another USB port to it using the USB camera pins, microSD socket (which did not work) and was working on looking for a tiny mini PCie true SATA card.

Here also have what appears to be an O2 prototype board that is the same as the Openpeak 2 except with a bunch of stuff removed and a socketed EFI boot chip rather than a soldered one. The motherboard is marked with red marker on both sides "O2". It boots up fine.

I had issues with the connected ZIF clip on the O2 Joggler where it remains on and I believe soldered correctly.

This was all many years ago.

I came across a batch of Openpeak 1's a few years back which look exactly like the Openpeak O2 except these have a metal heatsink that runs across the entire width of the mother board, PATA ZIF clip, Zigbee Chip, DECT chip and working microphone (for DECT chip use). These were being sold on Ebay in a trickle of sorts and coming from OpenPeak via 3rd parties. All of these were marked beta units and had an Openpeak logo O2 style on the case.

Purchased everyone of these I saw on Ebay being sold from around $35 up. I do not think most folks assumed that they were O2 Jogglers.

Modded these adding an RTC/battery, Realtek NIC ROM, PATA SSD drive and Aux USB hub. Never did add a digital audio output though.

The ZIF cable is just a flipped cable 40 or 44 pin cable. Fits nicely across the motherboard to the SSD drive. Set ups here have the WLAN stick, SSD drive and RTC on the left. I did clip out some plastic for this stuff to fit. Case closes / snaps together fine.

Today these are my base Jogglers as they each have a 16Gb SSD drive and aux USB port running embedded Windows XP from the SSD drive.

I have a few of these running Buzz's Ubuntu Linux. I did have one booting from the SSD drive. I do not know how I got this to work as I trashed it the other day and redid the whole using a USB SSD stick inside to boot to the PATA SSD drive such that I have 24 Gb of SSD drive and use the stick for the home drive.

Ideally getting the PATA port to work on the Openpeak 2 would be nice as the ZIF cable and SSD are relatively skinny enough to close the case. I did try a Broadcom Crystal mini PCIE card for being able to stream live TV on the Openpeak 2 with KODI. Worked great streaming movies, live TV and using SSD storage or a USB stick. The Openpeak 2 also has an RTC battery and Zigbee chip and DECT chip and microphone for telephony.

Some great stuff there Pete !

Any chance you could post some photos of what you've soldered onto the PATA port and from a few different angles ? I'm very interested to see what you've done.

The old O2 is somewhere here in pieces in a plastic bag. That said took apart last modified Openpeak which shows the ZIF clip and ZIF cable. Note here the flipped ZIF I used was too thin on one side so I put some scotch tape on side and carefuly trimmed it with a razor blade for a tight fit.

I have this one defaulting to Squeezeplayer and the eMMC is starting to go as I had to wipe it a few times with Andy's boot repair and write application.

I just now removed the SSD and USB stick and it took some 5 minutes to boot. Even Squeeze player is sitting at the logo for a very long time.
Definitely an issue here with the stall of the boot and related to the eMMC. Rewrote Andy's SP OS and it ran FSCK 3 times before it started to write to the eMMC. It still is stalling when writing to the eMMC. Wondering if I should try writing a seabios to the rom then booting to a USB stick in DOS to low level format the eMMC?

Seems that it checks the eMMC first before booting the USB/SSD card and that is where it is stalling.

This morning ran Andy's SP write to the eMMC. First and second time saw many fsck errors. 3rd and 4th time I saw no errors.

Going to maybe try swapping out the EFI rom boot chip to the Seabios rom boot chip and use currently configured 16GB ZIF SSD with embedded XP.

There will run the HDD guru low level format of the eMMC to see if it fixes it?

Meanwhile here replaced the 8 Gb SSD USB stick with a 16 Gb mini USB stick with same booting stuff to the 16Gb SSD.

Booting fine now to the 16Gb SSD. So I have a total space of 32 Gb for Buzz's build. Last configuration moved the home directory to the USB boot.

Now wondering if I deleted the partitions on the eMMC if the EFI boot rom will just go to the USB stick first?

Fixed the eMMC partition such that it doesn't stall when booting. Not sure how long that will last though. A while back did get the SSD drive to work booting and running the OS. Not there yet. Installed a new micro 16Gb USB stick and using the boot partition there to boot to the SSD partition just pointing to it in the boot config file. I also installed a new micro USB TP-Link WiFi dongle on the device. Works great. TP-Link offers a Linux solution build a driver which worked well. A while back found a 64Gb MLC SSD drive. Never could get Linux to recognize the drive. Never found reasonably priced 32 Gb SSD drives here only many reasonably priced 8Gb and 16Gb SSD drives. I see the flipped 40 pin longer ZIF cables are scare these days. One thing too is if I connect the SSD to a ZIF cable to a SSD to USB the drive boots up fine. Easiest way for me to use the SSD is to use the USB to SSD device to write Linux or Windows embedded images to it.

I have over the years documented this stuff here on the Joggler forum. I do this for my self here as I always let my fingers do the walking and don't pay much attention to nomenclature of what I am doing. IE: many times I am not physically thinking what my hands are doing; sort of like dialing a phone number but not remembering the telephone number.

Today for my embedded XPe screens replicated them backing up the image in vivo to a USB stick then writing image to a new SSD drive. Works 100% of the time.

Still on a need to do list some day is to upgrade the OpenFrame 2 with an SSD drive and use of a microSD boot drive. Figure out the DECT stuff and Zigbee stuff for use.

One of the best pieces of hardware to the Openframe 1 versus the O2 was a solid heatsink the entire width of the motherboard. This is also present in the Openframe 2 devices. There are two indents on these heatsinks; one for the CPU and another for the GPU.

Been playing here with Node Red and Mosquitto. Thinking of making the Joggler a display touchscreen for Node Red.

There is a lot of life left in the Jogglers today as these devices with their glass touch screens were made to last forever.

As mentioned previously here primarily use the Jogglers for XPe automation screens (15 of them). Most of these are POE Gb connected to the network with a few now connected only via WiFi. These also do Microsoft SAPI TTS/VR. Been collecting SAPI voice fonts here since the late 1990's. Nice variety versus one voice say for Alexa, GV, et al.

Squeezebox players (4-5 of them). Well now looking at Node Red.

Before I started to change stuff here I was able to boot from only the ZIF SSD drive. I did redo the USB stick and the SSD drive was booting form the USB stick.

What I did though is change the name of the boot partition to all capital letters and the grub.cfg and fstab were showing the partitions in lower case.

(fat fingered the naming of the partitions)

Changed the grub.cfg and fstab such that the Joggler now boots from the SSD rather than use the USB to boot.

Now changing the USB stick such that it just becomes a home drive disk when booting.

Now internal to the Joggler have 32Gb of play space and went to using a nano USB wifi stick for wifi which works fine.

Relating to pata SSD booting from the EFI boot a while back thinking a forum user mentioned that the Avaya boot rom had the SSD boot stuff built in.

That is why I am using it today with any model of the Jogglers or Openpeak devices.

It is sugggested to also write a new ROM to the Realtek built in NIC. Doing so will let you suspend and use a WOL to wake up the Joggler with a magic packet and have a MAC address as the original rom on any model Joggler doesn't have a MAC address.

Optional too is the installation of an RTC with battery. Note that the Openpeak 2 already has a battery in it.

Just a bit of bit banging and loading up the RTC on boot.

Another option is the addition of a small USB hub to the back of the Joggler using the motherboard pins for USB 2.0 as documented on the Joggler Wiki.

And still another hardware option is the installation of an optical HD audio port fitted to the back of the Joggler. This too is documented in the Wiki.

I have not played much lately with the Joggler hardware as it has been working just fine these days.

Basically here just wrote Buzz's Ubuntu latest desktop image to a PATA SSD ZIF drive using a small ZIF to mini USB card.

Expanded the image to the size of the SSD.

Used GParted to rename the partitions to linux-boots, linux-swap2 and linux-roots

Edited the /boot/grub.cfg file like so:

loadfont /unicode.pf2
terminal_output gfxterm
set timeout=5
menuentry "Xubuntu 14.04 LTS (Trusty) - 3.2.84joggler1" {
linux /vmlinuz-3.2.84joggler1 root=LABEL=linux-roots ro quiet splash
initrd /initrd.img-3.2.84joggler1

Edit the /etc/fstab file like so:

# /etc/fstab: static file system information.
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
LABEL=linux-roots / ext4 errors=remount-ro,noatime 0 1
LABEL=LINUX-BOOTS /boot vfat defaults 0 0
LABEL=linux-swaps none swap sw 0 0
tmpfs /tmp tmpfs defaults 0 0

You can keep the entire working partition to the PATA SSD card. Here used a 16Gb USB stick for my /home directory stuff. Easy to do this by:

1 - create a new ext4 partition on the USB stick using Gparted from the Joggler Ubuntu desktop
2 - mount a new home directory locally on the SSD IE: say /media/home
3 - rsync /home to /media/home IE: sudo rsync -aXS --exclude='/*/.gvfs' /home/. /media/home/.
4 - edit your /etc/fstab file to include or use the new home partition
IE: /dev/uba3 /home ext4 defaults 0 2

Hardware required:
1 - ZIF clip
2 - USB to ZIF drive case with USB to ZIF board
3 - Flipped 40 Pin ZIF cable - ~ 14 cm long and folded as in picture - blue and blue ends are thicker and work better. With a white end you need to thicken it a bit for the clip so I used scotch tape.
4 - you can fit the PATA SSD drive on the left over the USB WiFi stick just fine. I used a bit of painters masking tape.

One other issue that I have seen in the last few years is that the barrel connector / NIC / Audio board ports sink in to the Joggler. This can cause an intermittent power connection to the Joggler. This is because the board is mounted with hot melt glue. The easy fix is just to heat up the glue until it melts a bit while holding the board in place. To get to the combo board you have to remove or move the motherboard over a bit. I used a BBQ grill gas lighter with a stalk to heat up the hot melt glue just for a few seconds such that I do not melt the plastic around the board.
