No U-Boot via DEBUG/Serial

Hi all,

I am new to Renesas.

I have received R-Car M3 started kit and i want to boot yocto linux / AGL.

I have followed and completed all the procedure to build yocto, and I have also tried pre-built AGL image

But no image was loaded.

 

then I followed  https://elinux.org/R-Car/Boards/M3SK#Quick_Start_How_To, both under Linux and Windows.

The drivers are installed correctly, and the USB serial is detected, but nothing is received from the board upon power-up.

I also make sure all SW are configured correctly.

 

Thanks

Ron

  • Hi RonPer,

    Thanks for your inquiry.

    If you connect serial console to Windows PC, please confirm whether new COM port is available.
    ( Please beware of USB lock operation if your PC has strict security, e.g. PC in an organization.)

    I have some suggestion to check the SW settings in the board.
    Please refer to elinux.org/.../M3SK for SW settings for 02 boot modes:
    Set as step 2. for mini monitor boot. After applying the SW settings, please press SW8 (to power on the board) or SW9 (to reset the board). Could you see log output ?
    Set as step 4. for Linux boot. After applying the SW settings, please press SW8 (to power on the board) or SW9 (to reset the board). Could you see log output ?
  • Hi KHIEM,

    Thank you for the very fast replay.
    Unfortunately, I did not succeeded.

    Regarding the Windows PC - I can see in the Windows Device Manager the COM Port correctly as a USB Serial. When disconnecting the USB cable from the M3 board this COM port disappear as well.

    I have tried both under Windows PC and Linux PC, both Step 2 and Step 4 SW configuration, without any success.
    There was not even a single UART print.

    Regards,
    Ron
  • Hi KHIEM,
