[ANSWERED]JLink commands

chrish · Mar 15th 2010, 7:19pm

I am trying to use a L138 and IAR Embedded Workbench, and I was wondering what the JLink commander commands are for the following:

JTAG.IRLen=6;

JTAG.IRPOST=6;
JTAG.DRPOST=1;

JTAG.IRLen=4;

CPU=arm926ejs;

I need to create a setup macro file, but these are not part of the CSPY macro language and aren't documented in the help text of JLink commander.

Thanks,

Chris H.

Hi Chris,

seems I overlooked this post. Sorry.

The commands you postet are from the J-Link scriptfile syntax.
If I understand you correctly, you are trying to port these commands to a IAR EWARM macro file.
I am not sure if IAR EWARM supports JTAG chain configuration commands.
To get an overview about all commands supported by the EWARM macro file syntax, please refer to the appropriate manual.

C Source Code

JTAG.IRLen=6; // IR length (in bits) of device which J-Link is communicating with
JTAG.IRPOST=6; // Total number of IR bits of all devices in the JTAG chain which are closer to TDI than the device which J-Link is communicating with
JTAG.DRPOST=1; // Number of devices in the JTAG chain which are closer to TDI than the device which J-Link is communicating with
CPU=arm926ejs; // CPU core of the device which J-Link is communicating with

Best regards
Alex
