Re: [U-Boot] Prevent dropping into a shell triggered by serial port

Dear sunimohan,

when I try to boot, uboot always drops into the shell. If I remove the serial port connector, it boots happily.

If this happens even if you don't transmit data over the serial line tht you should fix your hardware. Seems you have floating signals, so add appropriate pull-up or pull-down resistors.

Looks like the Com device is responding to the boot messages from uboot and uboot is dropping into the shell.

Sounds like a hardware-related issue to me.

Best regards,
