Description: One of the prerequisites for becoming a giant is to have a complete ecosystem service: 1. SEGGER’s J-Trace is supported by its own Embedded Studio, which can be used with various well-known debugging components like RTT, J-Scope, Ozone, etc. Moreover, almost all popular IDEs support JLINK/J-Trace. 2. ARM’s DSTREAM series is supported by its own DS-5 and Arm Development Studio, but it does not support MDK. However, this does not prevent DSTREAM from becoming a giant.
1. Pricing DSTREAM is priced at $3500 each:
J-Trace Cortex is priced at $2498 each:
2. Performance DSTREAM is mainly used for the Cortex-A series, and many advanced features are not well understood, so it’s hard to directly compare it with J-Trace. Fortunately, the official website has a comparison between DSTREAM and ULINK, which allows for indirect comparison:
DSTREAM’s trace performance is significantly stronger than ULINKpro.
The configuration of J-Trace is as follows:
It has a maximum trace clock of 150MHz, which roughly translates to 1.2Gbps for 8 lines and 600Mbps for 4 lines, clearly not a match for DSTREAM. Additionally, both DSTREAM and J-Trace support USB 3.0 and Gigabit Ethernet.3. Ecosystem
In terms of ecosystem, J-Trace has virtually no competitors; any software supported by DSTREAM is generally supported by J-Trace. However, the reverse is not necessarily true.
4. Appearance J-Trace upgraded its casing last year, providing a better feel:
DSTREAM also looks quite premium:
