Board could not be detected when running setup.sh

There are two manual setting. One is /dev/ttyS1 and the other is IP address 192.168.1.20.
I get the information successfully in ttyS1 like what shows below

Hi Titus, I have tried setting boot mode to no-boot mode by setting SW1 1111 and changed /dev/ttyS0 from /dev/ttyS0 to /dev/ttyS7 and from /dev/ttyUSB0 to /dev/ttyUSB7 but it didn't work.

I am confused about the second reply you post. I did use USB cable(J1) and /dev/ttyS1 to get the uboot logs just like the top of the putty screen shot.

So I think /dev/ttyS1 is the right setting.

Hi Titus, I'm a fool. I did set boot mode to no-boot mode but I didn't realize I unplug the usb-serial cable until now. Now I have detected the board but it stop at somewhere as follows.

Detecting connection to board... k2e-evm autodetected at /dev/ttyUSB0

Please verify that this is correct or manually enter the correct port:

Would you like to run the setup script now (y/n)?

Please connect the ethernet cable as described in the Quick Start Guide.
Once answering 'y' on the prompt below, you will have 300 seconds to connect
the board and power cycle it before the setup times out

After successfully executing this script, your EVM will be set up. You will be 
able to connect to it by executing 'minicom -w' or if you prefer a windows host
you can set up Tera Term as explained in the Software Developer's Guide.
If you connect minicom or Tera Term and power cycle the board Linux will boot.

It autodetect the board at /dev/ttyUSB0 instead of /dev/ttyUSB1 you suggested. I have tried /dev/ttyUSB1 but nothing changed. And according to  I have tried to connect the board both at first and during but nothing changed. 

Thanks for your quick reply! Well, it seems not correct cause it shows BMC info. as follows. Should I input something it BMC mode? Does reboot means power down and up the board?

Sorry Titus, I make a mistake about "reboot" you said before. I think it's just powering down and up. Now I get the u-boot shell but I think there is something wrong about serverip.

This step will set up minicom (serial communication application) for

For boards that contain a USB-to-Serial converter on the board such as:
	* BeagleBone
	* Beaglebone Black
	* AM335x EVM-SK
	* AM57xx EVM
	* K2H, K2L, and K2E EVMs

the port used for minicom will be automatically detected. By default Ubuntu
will not recognize this device. Setup will add a udev rule to
/etc/udev/ so that from now on it will be recognized as soon as the board is
plugged in.

For other boards, the serial will defualt to /dev/ttyS0. Please update based
on your setup.

--------------------------------------------------------------------------------


NOTE: If your using any of the above boards simply hit enter
and the correct port will be determined automatically at a
later step.  For all other boards select the serial port
that the board is connected to.
Which serial port do you want to use with minicom?
[ /dev/ttyS0 ] /dev/ttyUSB0

Please connect the ethernet cable as described in the Quick Start Guide.
Once answering 'y' on the prompt below, you will have 300 seconds to connect

After successfully executing this script, your EVM will be set up. You will be 
able to connect to it by executing 'minicom -w' or if you prefer a windows host
you can set up Tera Term as explained in the Software Developer's Guide.
If you connect minicom or Tera Term and power cycle the board Linux will boot.

K2E EVM # 

First, I manually set serverip 192.168.1.20 both on PC and at line163 but when it came to the line 288, it becomes "TFTP from server 192.168.1.1; our IP address is 192.168.1.150".

Second, I use DHCP and serverip is nothing. When it came to the line 288, "TFTP from server 192.168.1.1; our IP address is 192.168.1.150".

At last, I manually set serverip 192.168.1.1 both on PC and at line163 and it shows as above.

I don't want to set "192.168.1.1" as the serverip. I tried to set "192.168.1.20" as the serverip but when it reboot, it auto-change into "192.168.1.1".

I have tried what you told but the board sticked to BOOTP broadcast as follows.(The board connected directly.)

Yes. 192.168.1.20 is the IP address of my VMware PC. I don't think the problem is the setting of NFSroot or TFTProot cause it has not run so far yet. I set the serverip 192.168.1.20 and ipaddr 192.168.1.25. And I  ping from the board to PC correctly. Then I boot, fail and ping again. It fails too! It says I don't set the 'ipaddr' env which can be found by 'printenv' command. I setenv ipaddr again and the ping succeeds. I am confused about the result and I print my info. as follows.
