JTAG-lock-pick - BASIC version

It was a long time since my last posting on the website, so I thought it would be a good idea to post a photos of BASIC version of JTAG-lock-pick that I assembled some time ago. But first things first...

As some of you know (and others will learn in a second), JTAG-lock-pick can be assembled in two versions (generally - not including dozens of variations):

  • FULL - JTAG + UART + RS-232,
  • BASIC - JTAG only.

Of course one can assemble "something in between" like JTAG + UART or JTAG + RS-232.

Photos of the FULL version can be seen in the previous news and on the elektroda's board, but there were no photos of the BASIC version published anywhere. So here they are - I present you the photos of BASIC version of JTAG-lock-pick - PCB with elements and the device in a case.

(higher resolution photos - HERE - at the end of the album)

As you can see, there is a lot of free space on the board (;

I'm writing some new articles (mainly about ARM and coding), so don't think the site is dead! Also I haven't forgotten the JTAG-lock-pick manual, so - STAY TUNED!

This news is pretty late, mainly because some server / site problems.

JTAG-lock-pick project is a complete success [; The device worked right after the soldering, which turned out to be much easier than I expected (the PCB is heavily packed with elements). Below - the photos of the pcb and the JTAG (without and with the case).

In Download > Projects > JTAG-lock-pick you can find a few basic files that are required for assembling (schematic and BOM) and starting (EEPROM template for MProg, drivers and an extremely short manual of starting and installation) this project. The complete manual is on it's way - be patient - I will finish it for sure!

New ARM JTAG - final schematics and PCB
Written by Freddie Chopin

In Download > Projects > JTAG-lock-pick final schematic for new ARM JTAG was posted - the project will be named JTAG-lock-pick. You can find more info on elektroda's board (Polish only). People interested in this project are encouraged to download the file. The PCB presented below is based on that schematic.

Changes introduced to previous version (0.0.3):

  • 74LVC2G125 double buffers in place of single ones (...1G125) to make things smaller - the most important gain is decrease in the filtering capacitors count,
  • one of 74LVC1G14 inverters removed - 3.3V voltage is always active and D_USB LED is driven directly by PWREN pin,
  • many minor changes like order of signals in resistor packs or dual buffers.

I'm ordering the PCBs tomorrow (; They will be scheduled for second week of March. Stay tuned!

In Download > Software > OpenOCD you can find OpenOCD 0.1.0 compiled for Windows in a convenient form of msi installer (Microsoft Installer). OpenOCD can communicate with ARM cores via many different ARM JTAGs and it can be used in any opensource toolchain which uses GDB for debugging.
