  • [SOLVED] LPC804 not found ...


    I'm trying to set up with an NXP OM40001 development kit. It's an LPC804 Cortex M0. User guide here: https://www.nxp.com/docs/en/user-guide/UM11083.pdf

    The on-board SWD is disabled as per instructions for J1.

    Below is the output from J-Link. Any ideas on what to try next?


    Source Code

    1. J-Link>connect ?
    2. Device "LPC804" selected.
    3. Connecting to target via JTAG
    4. Could not measure total IR len. TDO is constant high.
    5. Could not measure total IR len. TDO is constant high.
    6. TotalIRLen = ?, IRPrint = 0x..000000000000000000000000
    7. TotalIRLen = ?, IRPrint = 0x..000000000000000000000000
    8. Cannot connect to target.
    9. J-Link>

  • Hello,

    Thank you for your inquiry.
    The specified eval board does not support JTAG. SWD must be used instead.
    A successful connection using an external J-Link can be seen in the attached picture.

    Best regards,
