Connect Microchip SAMA5D27-SOM1-EK1 ...

debugasm

Hi,

I installed ARM Development Studio with a 30-day evaluation to build the first prototype with Microchip SAMA5D27-SOM1-EK1. To my surprise I realized that I cannot connect to the card using JLink on board.

I then used the SEGGER J-link GDB, with which I connected without problems.

However, I can't find the method to connect ARM Development Studio to the local GDB to debug device.

Before changing the Jtag of the board to connect my ULINK2 I wanted to know if there is a possible solution ?

With ARM Development Studio, can't you remotely debug a custom board that uses a Bare Metal software ?

Thanks very much.

    Hi debugasm

    Yes, Arm Development Studio is able to debug SAMA5D27 bare-metal, via a debug unit such as DSTREAM-ST or uLINK2.

    Arm DS does not use GDB(server) for bare-metal, though gdbserver is used by Arm DS for Linux Application Debug

    To connect bare-metal, use New Debug Connection > Hardware Connection, give the connection a name, then enter SAMA5D27 in the selection dialog:



    Follow the prompts to the "Edit configuration and launch" dialog, where you can select ULINK2:


    Hope this helps

    Hi Stephen,

    thank you very much for the detailed reply.

    I will try to use ULINK2 after building a 20-pin 10-pin 1.27mm pitch adapter.

    However, you confirm that remote debugging of a Bare Metal software is not possible at present. Will it be in the future ?

    Hi again debugasm

    Bare-metal debug is performed via our range of JTAG/SWD debug units such as DSTREAM & uLINK, or via a CMSIS-DAP connection (over USB).  Sorry, we have no plans to support bare-metal debug via a local GDB agent.
