During porting of U-boot on mpc8280 (U-boot port of MPC8260ads as base) I am facing following problems. I was able to burn the u-boot onto the flash. The first part of intialization was fine ie board_init_f () including the SDRAM (256 MB) initialization. The board gets hung during the second part of initialization. But the same piece of code works fine when I run from RAM using the JTAG. Is there any specific way to solve this problem?
Aaaaaaarrrrrrrgggghhhhh!!!!
Is nobody readuing mailing ist archives or FAQ's any more?
Obviously your JTAG debugger performs the correct SDRAM initiali- zation sequence which is missing in your code. And no, this has NOTHING to do with the UPM tables.
