All download speeds are taken from specifications found on manufacturer's website on March 20, 2007. If different values have been found, the highest one has been used. Please note that the actual speed depends on various factors, such as JTAG, clock speed, host CPU core etc.
Measuring J-Link download speed
JLink.exe has been used to measure performance. The hardware consisted of:
- PC with 2.6 GHz Pentium 4, running Win2K
- USB 2.0 port
- USB 2.0 hub
- J-Link
- Target with ARM7 running at 50 MHz
A screenshoot of J-Link Commander shows how the measuresment has been performed.
