- Added NAND as a configuration option in boards.cfg
Yes this is correct ..
[...]
- Added NAND support in omap4_common.h configuration file
as below (Just copied the lines from am335x_evm.h --- a/include/configs/omap4_common.h +++ b/include/configs/omap4_common.h
These changes look ok..
[...]
- Edited omap4_panda.h to prevent a compilation error
(The ENV gets setup as NAND thanks to earlier change);
This should be in include/configs/omap4_common.h itself #if defined(CONFIG_NAND) #undef CONFIG_ENV_IS_NOWHERE #define CONFIG_ENV_IS_IN_NAND #endif
[...]
- Copied over 2 header files from arch-omap3 to arch-omap4
(since they are from the same processor family, I'm hoping it will work) cp arch/arm/include/asm/arch-omap3/mem.h \
arch/arm/include/asm/arch-omap4/mem.h
I'm about to send the patch for fixing this.. However you can proceed Like this for now..
cp arch/arm/include/asm/arch-omap3/omap_gpmc.h
arch/arm/include/asm/arch-omap4/omap_gpmc.h
This should not be required if you pull in my below patch-set http://lists.denx.de/pipermail/u-boot/2013-November/167696.html
[...]
- Edited cpu.h to add a few structure members needed
for BCH error correction (compiler complains they are missing otherwise);
Again, this should not be required if you pull in patch mentioned above
[...]
- Adding a #define in omap.h to allow NAND driver to compile
(The value of ELM_BASE was copied over from arch/arm/include/asm/arch-am33xx/hardware.h)
Please double check the OMAP4 TRM, ELM_BASE shouldn't change though.
[...]
With the above, I'm able to compile u-boot.img, but am having trouble with the SPL. Here's where the build fails,
Please pull in my above patch-set mentioned above, and it should Solve this compilation issue.. The patch is compile clean as tested with ./MAKEALL -s omap4
Any suggestions on how I could fix this? I can't seem to figure out how SPL is built and am not sure where to start.
Plz pull the patch mentioned above, and much of things should be cleaned up http://lists.denx.de/pipermail/u-boot/2013-November/167696.html
Assuming that we can solve this issue, I can submit a proper patch after running it on real hardware (which should arrive in about 2 - 4 weeks).
Thanks..
Puzzled,
?? why ?? Its ok, you will figure the solution :-) (Also plz send plain text emails on u-boot maillist, no HTML please).
with regards, pekon
