 Posted: 29.11.2007, 16:26 Post subject: Kernel with console on ttySA1 |
 |
|
Some DNP1110 modules do not boot with kernel console configured on ttySA1:
CONFIG_CMDLINE="root=/dev/ram0 mem=32M console=ttySA1,9600"
but boot normally with default settings (ttySA0,114k):
CONFIG_CMDLINE="root=/dev/ram0 mem=32M"
They hang after the "Uncompressing Linux................................... done, booting the kernel" message.
Does anyone have similar experience or a workaround for this problem? |

Please try to use the same baudrate (115.2K) we normally use on ttySA0 on ttySA1 as well! Then try again.
Please check your physical connection on ttySA1 and the cable to the host.
You'll require a null-modem cable. Check your terminal settings.
Anyway the hardware could be damaged also!
Regards,
