I chose TFTP and NFS mode and expected that it would fetch boot image from /tftpboot directory and mount /home/jongampark/targetfs directory as s remote directory.
So, it looks like that it will be OK not to insert an SD card which contains boot image.
However, it turned out that I had to insert the SD card.
Only after inserting the card it prints out messages to a minicom or any serial terminal program.
U-Boot 2010.06 (Oct 10 2012 - 02:04:37)
DRAM: 2 GiB
MMC: OMAP SD/MMC: 0
Using default environment
Hit any key to stop autoboot:
...
Well, it doesn't look to accept any keyboard input at that moment.. then it reads a u-boot.bin. ( probably it reads from the SD card, because it didn't received my hitting a key at that moment.
Then overall procedure is like this.
What is shown is...
I just typed what the minicom script generated by the setup.sh was supposed to put.
And as you can see, it just displayed "Erasing Nand..."
I don't know how long it will take to finish "erasing NAND flash memory".
It already passed more than 10 minutes.
But when I booted from the SD memory earlier, it said that there was no NAND device.
So, I wonder if the current message is correct or not.
Do you think there is something wrong? If so, what is it?
Also, the minicom script doesn't look to operate correctly. I doubt if it successfully detects "stop auto boot:" message and send a key ( in the script i is send "" ) successfully.
How can I check if the tftp server is sending any data to the reference board and how to figure out how much it is progressed?
( It still displays "Erasing Nand...")
I wonder if an expected u-boot.bin was loaded at right after the first "Hit any key to stop auto boot: 0" line.
If it is to be loaded from tftp for boot image and filesystem on my local HDD, then I expect it should be OK not to insert the sD card at all.
(whether it's the SD card bundled with the reference board or the one I built by following the SW programming guide )
It is strange that the SD card should be inserted to see the very initial prompt messages at least.
Can somebody guide me?
Thank you.
P.S. I asked in other thread also. Please someone help me. I'm just wasting time to configure a dev. environment.
