How long will my memory last?

Published by under General

I am not about to answer the question literally because most would say I have no memory at all based on the lists and notes that clutter my desk.  Actually I am more inclined to answer the question as applied to the PIKA WARP appliance.  It is a very common question I am asked because unlike less destructive methods of storing electronic data, writing to flash memory (like found on the appliance) has a measureable life span.  That being said for a limited number of write operations, flash memory – with no moving parts – will typically last longer then the traditional hard drive which is spinning away. 

First and foremost the appliance’s NAND based memory chip itself has a “write-life” and once exceeded the chip can no long be written to.  So what do these numbers actually work out to?

New PADS Software Release –

Published by under General,News,Software

Just a notice to everyone using the Warp. There has been a new release for PADS, version, for the PIKA appliance. This new release is the one that will be flashed on all appliances that PIKA ships, replacing the GA version. This release can be retrieved from the public svn repository here:


Why the new release you ask. Well this release contains the following enhancements over the GA version:

  1. Enables the autoflash from USB by default
  2. Adds support for autoflash from SD cards
  3. Echo cancellation improvements
  4. Fixes an issue with the audio line in and out ports where paging disrupted music on hold
  5. Fixes an issue with calling reload of the pika channel driver in asterisk that resulted in one way audio.


Lots of good things here. Enjoy everybody.

10 things I didn’t know 18 months ago

Published by under General

A year and a half ago I didn’t know and barely cared about any of the following 10 things. Since that time however, I have had the fortunate opportunity to be involved (from a safe distance I assure you) in the development cycle of PIKA’s WARP Appliance.  It introduced me to a number of new aspects of both product manufacturing and the design and implementation of an embedded device.  This is not a complete list by any means, merely the ones that stick out in my mind and that I feel like sharing.

How-To: Make an Asterisk file persistent

Published by under How-To


Currently PADS will build the asterisk package and install the files in the RAM disk image (uRamdisk) and the /persistent (image.jffs2) partition. The files that are installed in the RAM disk image are not persistent across reboots. On the other hand, the files that are stored in /persistent partition retain their values across reboots.
