Kernel command line modification: ttyS0 vs ttyUSB0

Kernel command line modification: ttyS0 vs ttyUSB0

  • Hi!

    Sorry for my bad English

    My serial port didn't work, so I used a serial USB adaptator. I have chosen as mean of communication: serial, with /dev/ttyUSB0 and as mean of installing image: serial

    When I run "make install" I have no problem but when I run "boot" (with uboot prompt) I can see the Kernel command line:

    setenv bootargs console=ttyS0,115200n8 davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=720x480 dm365_imp.oper_mode=0 davinci_capture.device_type=3 mem=84M root=/dev/nfs nfsroot=192.168.1.172:/home/stephane/DM365SDK844703/fs/fs rw ip=dhcp mtdparts=nand_davinci.0:3968k(UBOOT),128k(UBOOT_ENV),3200k(KERNEL),204800k(FS)

     

    whereas I want to have console=ttyUSB0

    How can I do to change it?

    I have looked at "bspconfig" and there is good: ttyUSB0

     

  • ps: Consequently, the boot doesn't work: it stops with DHCP sending....   timed out!   IP-Config: Retrying forever (NFS root)...

    ... DHCP sending...

  • I have solved my problem: I have changed my PC, and I choose a PC with a functional serial port !!
