Dear "Teh Kok How",
In message 006c01ca157b$e574acb0$1933000a@smartbridges.com you wrote:
I understand Wolfgang's argument but setting the TEXT_BASE to this arbitrary high address (DRAM_end - U-boot_size(_end - _start)) does not make sense. ...
Maybe it makes little (or even no sense) to you. But you should not generalize such a statement.
... I am new to ARM arch but in PowerPC and MIPS, the TEXT_BASE is always set to the reset vector ...
This is plain wrong.
See for example:
"board/tqc/tqm8xx/config.mk":
TEXT_BASE = 0x40000000
These are low-booting MPC8xx systems, i. e. the reset vector is 0x100.
"board/amcc/canyonlands/config.mk":
TEXT_BASE = 0xFFFA0000
This is a PPC460EX based system, i. e. the reset vector is 0xFFFFFFFC
... and in ARM, the reset vector is at 0 or 0xFFFF0000.I have tried both values but still failed to boot u-boot on the board....:-(
No big surprise since your changes are based on misunderstandings.
Best regards,
Wolfgang Denk
