[RM57Lx HDK] Debug probe vs J-Link Emulator

Other Parts Discussed in Thread: SEGGER

Dear community,

I have one RM57Lx HDK. I've compare debug speeds between "CCSv6.1 + XDS100v2" and "IAR EWARM + J-Link EDU / XDS100v2". I was not able to use "CCSv6.1 + J-Link EDU", because Segger's J-Link support for CCS v6.1 always crashes in the debugging process.

The result is confusing and unbelievable:

"CCSv6.1 + XDS100v2" >> "IAR EWARM + J-Link EDU" >> "IAR EWARM + XDS100v2"

"IAR EWARM + J-Link EDU" is much faster than "IAR EWARM + XDS100v2", and "CCSv6.1 + XDS100v2" is much faster than "IAR EWARM + J-Link EDU".

IAR EWARM license is quite expensive and J-Link emulator costs a lot as well, although both are educational licenses. "IAR EWARM + J-Link EDU" should be much faster than "CCSv6.1 + XDS100v2".

Perhaps the debug settings were not configured correctly. Does anyone have related experience? Any tip will be appreciated!

    Honig,

    I've used the J-Link (not EDU version) and the result were all the time faster than XDS100v2.

    Another option could be to use the XDS200. It's way faster than XDS100v2 and still very affordable ($295)
    It is supported in CCS and IAR as well.

    I will run some test next week on J-Link and RM57Lx HDK.


    Happy Holidays.

    Hi Jean-Marc,

    > I've used the J-Link (not EDU version) and the result were all the time faster than XDS100v2. <
    Which version of J-Link did you use? J-Link Base or Pro? Due to Segger website, J-Link EDU is a slightly improved variant of J-Link Base. Are there any special debug settings that should be correctly configured for "IAR EWARM + J-Link"? For the debug settings, I only followed every step in the official tutorial.

    Looking forward to reading your summary of the comparison test!

    Happy holidays!
