ATmega128 JTAG + Olimex JTAG
larwe - 10:22 25-12-05
Just a couple of quick questions about JTAG on the AVR series,
specifically the mega128, and the Olimex USB JTAG ICE. I haven't used
JTAG on AVR before.
1. Any positive or negative comments on the AVR-USB-JTAG from Olimex
vs. the JTAGICE from Atmel? It seems like the JTAGICE uses a
higher-spe...

Alice - 01:29 26-01-06
I'm new to learning about jtag and it's capabilities, and my professor
isn't helping me at all. I understand jtag is mainly used in
processors, but I was reading on Altera's website about a flash chip
(EPM3032A) they use that has jtag support. What jtag device would I

Roger - 08:54 26-01-06
My JTAG Cable1 has just failed and I need to get another JTAG programmer,

Obviously I'd get an Atmel JTAG ICE Mk11 if the cost wasn't so ridiculously
high so it'll have to be an alternative.

Maciej Kaczkowski - 13:27 01-06-04
How can I use JTAG mode without ETM port on Philips LPC 210x?
I pull up DBGSEL and RTCK during RESET, processor starts using jtag but
also ETM port is enabled (I can`t use ETM pins as GPIO).
I am also using LPC 212x - it is posible to turn on jtag without ETM port.
Thank You

I have a jtag programmer for xilinx devices ,is this a standard interface ?
Can i use this device to program other devices with a JTAG interface (eg

Or do i need a dedicated tjag interface for every Jtag device i intend to
use ? (whats the use of a JTAG standard then ?)
