  • [SOLVED] Multiple uC programming via JTAG boundary scan

    Hello,
    I have a couple of questions about flashing many microcontrollers (arm cortex M):

    1) Is it possible to flash two devices with one J-link with the same firmware using a j-link commander script? The idea is to connect via JTAG two devices and automate the flashing process
    2) Is it possible to flash many devices with one J-link with different firmware based on the device position in the JTAG chain using a j-link programmer script?

    if one (or more) of the points above is not feasible,
    1) is it possible to perform such oeprations using J-link SDK?
    2) would be possible to perform such operations using J-flash programmer?

    Please note that we can rely both on licensed J-link Plus and j-link Pro devices.

    K.R.

  • Hi Catosh,
    Thank you for your inquiry.
    Yes, this is possible.

    You can re-select the chain location device via "JTAGConf" command.

    Best regards,
    Fabian
