[U-Boot-Users] [Newbie]: mpc8260ads and u-boot
Sorry for a so newbie question. I tried to search trough the docs about u-boot and did not found any problem similar to mine. Then, since i am moving just first steps in this kind of projects, i tried to send a mail to get help.
The problem is simple: i compiled u-boot for my target, i erased all the flash, i downloaded the bin image on the target flash, i disconnected the lauterbach t32, turned off the board, connected the serial, and turned on again the board. I expected to see uboot menu, instead just nothing. "Run" led is always turned on, while "RS232" led is always off. Since i don't know what to think, what should i investigate to find out the problem? How can it be solved?
Txn in advance, Lele

Why did you disconnect the Lauterbach? You have got a powerful tool, so use it to debug your problem. This is what it was made for.
There are so many things you can have done wrong - burning the wrong image to the wrong address, using bad jumper settings or anything else...
