[U-Boot] MAKEALL ml507_flash return "Not enough room for program headers" error
Hi there,
I am trying to build a U-Boot image for the ML507 board running from FLASH and got the "Not enough room for program headers" error.
The main difference for my setup is the toolchain. I am using the powerpc-eabi-ld linker from Xilinx's EDK tool chain to build the ml507_flash design for U-Boot.
I have seen a patch on the linker script for the mpc8555cds board and tried adding the patch to the Xilinx/ppc440-generic/u-boot-rom.lds but got the "relocation truncated to fit R_PPC_REL24" error.
Before going further with debugging this problem, I would like to check if this problem is due to the powerpc-eabi tool chain from Xilinx?
Thanks for your help.
Regards,
Benny

Hi Ricardo, Changing my tool chain to the ELDK 4.2 ppc-linux-x86 does build the default ml507_flash project. However, because my hardware design does not map the FLASH chip to 0xFE000000 but to 0x86000000 the build failed with the following error.
/******************************/ cpu/ppc4xx/start.o: In function `rsttlb':
/usr/local/groundprobe/src/Bootloader/u-boot/cpu/ppc4xx/start.S:493: relocation truncated to fit: R_PPC_REL24 against symbol `_start' defined in .text section in cpu/ppc4xx/start.o /*****************************/
I think this issue maybe to do with the 24bit branch address limit with the PPC440x5 core. Here the _start_440 function calls a "b _start" and in this case the _start is mapped to flash in address 0x8600xxxx. Meaning we now need to branch from 0xFFFFFxxx to 0x8600xxxx. I think this is why the linker failed at the last stage.
Does anyone have any idea with this issue?

Maybe if you move your _start to the booptg section you will solve your problem.... or you can also modify the jump to be a long jump.

Hi Ricardo,
Thanks for helping with this issue. My real option is to do a long jump to the _start code. However, I am not familiar with the PPC assembler hence, I am not able to get the longcall working.
_start is written in assembler in cpu/ppc_4xx/start.S therefore, I need to do a longcall from assembler which I am not sure how to do. Could you please help advise on how I can do a longcall in assembler?
Further, investigation I found that the other option is to do a function pointer call to _start. When written in C this should force the use of the CTR register which is 32-bit to hold the _start address. But I don't know how to do this in assembler. If you have any idea on this it would be much appreciated.
Thanks once again mate.

Hi Benny and Ricardo,
How are you Benny?
I am not xilinx ppc expert but it seems to me that your problem is in Flash baseaddr. I haven't worked with ppc440 but I worked with ppc405. The point is that ppc starts on specific address. I think from end of memory space (address like 0xFFFFFFFC or any similar). Look at u-boot-rom.lds in xilinx folder. Then is jump in one page and there is relocation to ram. It is not hard to understand that - everything is in U-BOOT code. And in your case where the flash has lower address your compilation seems to me failed on linking because your target file is huge. You should move flash memory to the end of memory space.
PPC is a little bit different than Microblaze which you know. But you can of course add there bram memory and do any wrapper there.
Cheers, Michal

Hi Michal,
Good to hear from you.
You are exactly right about the issue with my FLASH not being mapped to the end of the memory mapped space. Hence, the initial boot code could not jump far enough to it.
I need a 64k BRAM block sitting on the end of memory address so I can't back my FLASH mapping right up to FFFFFFFF. However, I am trying to get it close enough so that the branch code can reach.
I am not sure if this is what you meant by "my target file is huge". But hey let me know if I am wrong.

Hello Benny
Maybe if you move your _start to the booptg section you will solve your problem.... or you can also modify the jump to be a long jump.

Hi Ricardo, Changing my tool chain to the ELDK 4.2 ppc-linux-x86 does build the default ml507_flash project. However, because my hardware design
does
not map the FLASH chip to 0xFE000000 but to 0x86000000 the build
failed
with the following error.
/******************************/ cpu/ppc4xx/start.o: In function `rsttlb':

I think this issue maybe to do with the 24bit branch address limit
with
the PPC440x5 core. Here the _start_440 function calls a "b _start"
and
in this case the _start is mapped to flash in address 0x8600xxxx. Meaning we now need to branch from 0xFFFFFxxx to 0x8600xxxx. I think this is why the linker failed at the last stage.
Does anyone have any idea with this issue?

Hello Benny
I have just checkout the build of the ml507_flash and works ok for
me
ricardo@aragorn:~/curro/qtec/u-boot$ ./MAKEALL ml507_flash Configuring for ml507 board... text data bss dec hex filename 202132 10476 30032 242640 3b3d0 ./u-boot
I remember that when I was using another toolchain the final link failed (but showing different error). Try with another toochain, I am using one produced by OpenEmbedded, but you will get the same results with the ELDK
Best regards

Hi there,
I am trying to build a U-Boot image for the ML507 board running from FLASH and got the "Not enough room for program headers" error.
The main difference for my setup is the toolchain. I am using the powerpc-eabi-ld linker from Xilinx's EDK tool chain to build the ml507_flash design for U-Boot.
I have seen a patch on the linker script for the mpc8555cds board
and
tried adding the patch to the Xilinx/ppc440-generic/u-boot-rom.lds
but
got the "relocation truncated to fit R_PPC_REL24" error.
Before going further with debugging this problem, I would like to
check
if this problem is due to the powerpc-eabi tool chain from Xilinx?
Thanks for your help.

Hi Guys,
The above error message was resolved by using the ELDK cross compiler. Previously I was using Xilinxs powerpc-eabi-xx cross compiler to build U-Boot.
Cheers, Benny

Hi Ricardo,
Thanks for helping with this issue. My real option is to do a long jump to the _start code. However, I am not familiar with the PPC assembler hence, I am not able to get the longcall working.
_start is written in assembler in cpu/ppc_4xx/start.S therefore, I need to do a longcall from assembler which I am not sure how to do. Could you please help advise on how I can do a longcall in assembler?
Further, investigation I found that the other option is to do a function pointer call to _start. When written in C this should force the use of the CTR register which is 32-bit to hold the _start address. But I don't know how to do this in assembler. If you have any idea on this it would be much appreciated.
Thanks once again mate.
Regards, Benny
