Hi,
I am working on DM368 reference design:
When i am installing the uImage_ipnc_dm368_IMX036_2.60.01 and cramfsImage_ipnc_dm368_IMX036_2.60.01 i am not getting anything.
My installation steps are as follows:
tftpboot 0x80700000 uImage_ipnc_dm368_IMX036_2.60.01
nand erase 0x500000 0x200000
nand write 0x80700000 0x500000 0x200000
tftpboot 0x82000000 cramfsImage_ipnc_dm368_IMX036_2.60.01
nand erase 0x700000 0xD00000
nand write 0x82000000 0x700000 0xD00000
setenv bootcmd 'nand read 0x82000000 0x700000 0xD00000; nboot 0x80700000 0 0x500000; bootm'
setenv bootargs 'mem=48M console=ttyS1,115200n8 root=/dev/ram0 rw initrd=0x82000000,16M ip=192.168.1.101:192.168.1.100:192.168.1.1:255.255.255.0:::off eth=00:0C:0C:’
earlier after doing this i was able to get full camera gui and display at the ip 192.168.1.168.Now using above procedure it doesn't ev en show the correct ip of the board using ifconfig.Also no application is running as was happening earlier.How can i be able to see the gui on the board.The output of printenv is as follows:
bootdelay=4
baudrate=115200
bootfile="uImage"
setboot=setenv bootargs $(bootargs)
ethaddr=00:22:19:fa:1a:b4
filesize=DCE000
fileaddr=82000000
ipaddr=10.17.8.131
serverip=10.17.8.125
bootcmd=nand read 0x82000000 0x700000 0xD00000;nboot 0x80700000 0 0x500000;boot0
bootargs=mem=48M console=ttyS1,115200n8 root=/dev/ram0 rw initrd=0x82000000,16M’

ver=U-Boot 1.3.4 (Dec 9 2010 - 17:44:14) DM368-IPNC-1.0.1
Environment size: 542/131068 bytes
Also when i make my own uImage:uImage_ipnc_DM368_IMX036 and cramfs:uImage_ipnc_DM368_IMX036 the board doesn't boot at all and it hangs in between.
and it hangs in the middle:The output i have posted on earlier posts on this forum only.
Please help me give me some hint how can i get over these issues.
I have some questions:
1.if we generate uimage and cramfs the does it sutomatically set correct bootargs or we have to do it manually on uboot prompt.
2.192.168.1.168 is the ip where we can see gui when the application runs,if the application doesn't run on kernel booting what kind of error does it suggest.
3.what bootargs are important for kernel to boot.Also once we generate uImage then cramfs must also be generated with the same environment if we want the board to boot properly or it can boot using the UImage only.
4.In appro reference design if we boot the board using the uimage and cramfs given by them then boot should boot fine and also the applications that run by default should also run.i am currently booting both the images fine but the board is not detecting the corrcet ip 192.168.1.101 and also no application runs,what could be the reason for that.
Thanks and Regards,
Mayank
