Hi Navin, What is the value you have given to TEXT_BASE in board/pxa255_idp/config.mk
Regards Amit

Infact I was looking for the info to create a proper 'tlbentry' in 'init.S' As per my understanding the 'tlbentry' is to map 32-bit address to 36-bit address.
The 'tlbenry' for the PCI Memory in 'init.S' is : tlbentry( CFG_PCI_MEMBASE, SZ_256M, 0x00000000, 3, AC_R|AC_W|SA_G|SA_I )
The 'CFG_PCI_MEMBASE' is set to 0x80000000 in 'ocotea.h'.
My question is how to select the value for 'CFG_PCI_MEMBASE'. Can I use any value (say 0x50000000 ) provided it is not overlapping with other devices?
Yes. I suggest to start with 0x80000000 since this leaves the first 2 GB for SDRAM.
If we are using Board Memory Map as a reference then the 32-bit address 'CFG_PCI_MEMBASE' used in 'telbentry' should have set to: 0x90000000
Why is this? Which "Board Memory Map" are you referring to?
I am trying to find out the logic behind the selection of value for the variabale 'CFG_PCI_MEMBASE' in: tlbentry( CFG_PCI_MEMBASE, SZ_256M, 0x00000000, 3, AC_R|AC_W|SA_G|SA_I )
Whats the problems with using 0x80000000 here?
Best regards, Stefan

-- Hi all,
I am new to this list, I planned port u-boot on my board(pxa255), followed the procedure in README and i am able to compile the uboot.
I loaded the image on board. The messages i got when i boot the board are
------------------------------------------------------------- U-Boot 0.4.5 (Jun 16 2008 - 12:24:00)
U-Boot code: A3000000 -> A301BD30 BSS: -> A301FE98 DRAM Configuration: Bank #0: a0000000 64 MB Bank #1: a4000000 0 kB Bank #2: a8000000 0 kB Bank #3: ac000000 0 kB -------------------------------------------------------------
and it stops at that point. Please give me an hint where i am making the mistake.
Regards, Naveen
