Dear Albert ARIBAUD,
I have tried to start update the eb_cpux9k2 board. I can compile board without errors from current tree. But the board hangs on NAND detection. If I disable NAND support, the board starts and I can also start Linux.
We've had issues in the past with boards that did not detect NAND. Can you look up the u-boot archives for this?
A second problem, the board does not restart (reset command). I find out that a NULL pointer used by reset code, was also relocated.
How did you come to this conclusion? NULL pointers are constants and thus are *not* relocated.
I have currently no access to a BDI2000. But I think, this problems are not board specific. It is possible, there are problems with vector tables or memory protection
Any suggestions?
I suggest visually running through all (board or cpu-specific) code that runs as part of execution board_init_f() and checking that no global is ever used -- BSS or initialized.
The board use 920t on at91rm9200 soc
