A: 

The Linux boot logos can be found in the directory "Linux kernel\/drivers/video/log", by replacing the ppm files there and then rebuilding the kernel you may change the boot logo 


A: 

MTD partition is defined in the file "arch/arm/plat-s3c/include/plat/partition.h", you may modify the partition information by modifying this file.


A: 

Yes there are many serial port terminal programs available in Linux, Minicom and Kermit for example, these two are included in most  Linux distributions. A tutorial for minicom can be found in our users manual, and information of kermit can be found here: http://www.columbia.edu/kermit/


A: 

this happens normally because the boot parameters are confirgured incorrectly. Try to download another large file to the bootloader section with the SJF2440 program to overwrite the parameters and then re-load the bootloader.


A: 

Both WindowsCE 5.0 and Linux 2.6.28 are pre-installed. The bootloader for our S3C2440 series development kit supports dual operating systems, i.e., you may install both Wince and Linux on the board at the same time and choose the either of them to run, or set either of them as default OS in the bootloader menu.


A: 

Normally such "bad blocks" are not real bad blocks. These blocks can be marked as bad blocks due to some faulty operations. Generally we can have this solved by running the "nand scrub" command in the uboot prompt, note that "nand scrub" will erase everything in your NAND, so please be sure to backup your data before doing this. Anyway, a few "real" bad blocks in the NAND Flash is normal and allowed and they would not effect anything.


A: 

 There are two possibilities:

 
1. The kernel image (zImage) has not been well installed.
 
In this case you just need to follow the user manual to install the zImage.
 
2. Incorrect u-boot parameter. In this case you need to:
 
1) Press any key during the boot delay to enter the u-boot menu;
2) press "e" to exit the menu and enter command line:
3) execute the commands below
    setenv bootcmd "nand read 0xc0008000 0x100000 0x400000\;bootm 0xc0008000"
    saveenv
    reset
 
Please note that the addresses (0x100000 and 0x400000) differ with each board, please consult support@arm9board.net for specific addresses.

A: 

 This happens mostly when switching the OS from WinCE to Linux/Android. WinCE marks the NAND Flash OOB partition in a way that Linux would not recognize, so these blocks in the OOB partition are reported as "bad blocks".

 
By executing a "nand scrub" command in the u-boot console we can get these errors resolved. Please note that the "nand scrub" command will erase everything in your flash, so please be sure to backup your data before doing this. 

A: 

Please check if the NFS client IP or port is being blocked by the firewall.

Run the commands below:

# service iptables stop

# service iptables status

# cat /etc/hosts

# cat /etc/hosts.deny

# cat /etc/hosts.allow
