Uboot serial console is not halting and uboot shell is not coming

Question asked by srinivasaporam on Jul 2, 2015

Hi,

We have got wandboard quad board with us. When we are deploying some prebuilt images, tand powering on the board, it is booting correctly. for the prebuilt images we are using (uboot as well as kernel (Ubuntu trusty)).

 

Actually we would like deploy only uboot and see the boot messages in serial console (for our development purposes)

 

for this we have done following things:

 

1. We have connected USB to Serial Converter (USB is attached to my Ubuntu PC which is running minicom and serial is connected to wandboard quad's serial port. USB to serial converter cable is working fine. this we have checked using putty.

 

2. We have installed minicom in my ubuntu machine and set the serial port configutation (ttyUSB0,115200 etc).

 

3. start the minicom, by issuing command sudo minicom -D /dev/ttyUSB0 -o -w then minicom screen coming.

 

4. after deploying uboot to sd card, then kept sd card in sd card slot of wand board and powering on.

 

5. once powering on, we are hitting space bar in the keyboard which is connected to wandboard,

then messages are being displayed but uboot shell is not coming.

 

the messages are also not in english. Please find the message as below:
