  • [SOLVED] wjraw returning malformed response

    I have upgraded to the latest FW and still see the following issue when using the l-link commander window. When I use wjraw to shift 8 bits, I'm getting a 4 bit answer back if the upper 4 bits are 0. This also happens when I ask for 32 bits back and this data is in the middle. Please see the log below:

    J-Link>rtap
    J-Link>wjraw 4,2,0
    TDO: F
    J-Link>wjraw 8,00,00
    TDO: 77
    J-Link>wjraw 8,00,00
    TDO: 4 <--- 4 bits only
    J-Link>wjraw 8,00,00
    TDO: A0
    J-Link>wjraw 8,00,00
    TDO: 4B
    J-Link>
    J-Link>
    J-Link>
    J-Link>rtap
    J-Link>wjraw 4,2,0
    TDO: F
    J-Link>wjraw 32,00000000,00000000
    TDO: 4BA0477 <--- missing bits
    J-Link>

    Can anybody comment on whether this is a bug, expected behavior, has a config option somewhere, etc.?

  • Hi,

    I will try to reproduce this issue later this week.
    While this looks like an error in J-Link Commander at first glance, could you please tell me which J-Link model+version and which target device you use?

    Best regards,
    Niklas

  • Hi,


    this issue has been fixed in version 6.14c of the J-Link software & documentation pack.

    Does this version work for you?
