Isn't the JTAG pinout [1] on the mini2440 a bit wierd? I've searched for programmers with the same pin assignment, with no luck. 1 - VDD33V 2 - VDD33V 3 - TRST 4 - RESET 5 - TDI 6 - TDO 7 - TMS 8 - GND 9 - TCK 10 - GND [1] http://www.friendlyarm.de/mini2440/mini2440_schematic.pdf
Yes, you must make a adapter cable for this pinout. The normal ARM JTAG connection is a 14 or 20 pin connector. The connector on the mini2440 is a 10 pin and with a pitch from 2,00 mm.
Thank you for the quick answer!
The Trition boards use the same layout. Selecting this layout you can use the JTAG shipped with the board with e.g. OpenOCD.
Hey, great! Thanks for the tip Florian!
I have a complete OpenOCD configuration for the m*2440 in the text here: http://labs.kernelconcepts.de/Publications/Micro24401/
what can i do if i dont have a LPT port in my computer for connecting the jtag cable?
I am going to buy the Signalyzer LITE:DT-USB-SLITE JTAG debugger that explained in the following link: http://www.xverve.com/development-tools/signalyzer-tool/signalyzer-lite-... Does this USB debugger compatible with the mini-2440 development kit? Also does the IAR Embedded Work-Bench IDE can be use with the USB Signalyzer debugger and the mini-2440 development kit? I hope you answer ASAP, as I am going to start project by the start of the new year. Thanks, --- A.Nabil
The Signalyzer LITE should work with this target as long as the target JTAG interface is 3.3V capable. In addition to original Signalyzer LITE and Signalyzer, we recently launched new Signalyzer-H series offering much higher TCK clock rate, support for RTCK and many more other features. You can find more information about Signalyzer H2 and Signalyzer H4 here: http://www.signalyzer.com/signalyzer-series/core-modules As with original Signalyzer, Signalyzer H2 provides two channels (both JTAG capable) and much more... --- Signalyzer – USB JTAG, I2C and SPI Embedded Systems Development and Manufacturing Tools for Windows, Linux and Mac OS X http://www.signalyzer.com
Hello, I have successfully tested opendous/estick jtag board with FriendlyARM: http://code.google.com/p/opendous-jtag/ it is a DIY Jtag Adapter based on AT90USB162 MCU: http://embsys.technikum-wien.at/staff/horauer/estick/estick.php or http://code.google.com/p/micropendous/
