[ABANDONED] Processors/Boards with good J-Link support

whiterabbit · Nov 9th 2021, 6:23pm

Which (ARM64) processors or single board computers do have the best support with J-Link?
I'm looking for some equivalent to the raspberry pi. Ideally it could dump memory at 1MB/s as specified here: segger.com/products/debug-prob…nk/models/model-overview/ Is this possible? Does the overall speed depend on the J-Link or the processor on the SBC?
I have the edu version.

The memory read / write speed mainly depends on the following factors:
- Selected TIF (JTAG, SWD, …) speed
- Target MCU speed
- J-Link model

Any SBC should be easily able to achieve USB speeds of > 1 MB/s or even 3 MB/s, so even the ULTRA+ / PRO models should be able to unleash their potential on these SBCs.

Here you can find a list of SBCs that have been tested with J-Link:

Thx. But I meant kind of the opposite. Which boards are most suitable for acting as debuggee i.e. where the J-Link hardware is connected to and analyzing the SBC. The rpi seems to have no support. Boards with NXP processors seem to have good support. Any others? Could you debug something like the HummingBoard Pro developer.solid-run.com/knowle…base-pro-getting-started/ at ~1/3 MB/s ?
