[U-Boot-Users] Relocation code on...

Hello,

I'm noticing that the examples directory fails to compile with gcc-3.4.0. The _exports.h symbols are not making it into stubs.o .

I found that the compile works if you:

Change: static void __attribute__((unused)) dummy(void) to: void __attribute__((unused)) dummy(void)

This would seem to be a new optimization or bug. I would expect that unused should make it stick around, even if it is not used locally.

The kernel uses this same construct in a few places mostly in debug code and drivers I don't' use...

Regards,

Richard W.

Thanks for pointing out. I think I'll enable the "static" part only for GCC_VERSION <= 3004.

New subject: [U-Boot-Users] Protected Flash (newbie question)

Hi,

I've just compiled and downloaded a copy of u-boot to my Hynix 7202 ARM720T board. I have got a puzzling error, however, when I try to save my updated env variables:

uboot> saveenv Saving Environment to Flash... Un-Protected 1 sectors Erasing Flash...Erasing sector 1 ... ok. Erased 1 sectors Writing to Flash... Flash write error 92 at address 00020000 Device protect error. Can't write to protected Flash sectors Protected 1 sectors

I've tried 'protect off 20000 3ffff' and then 'save env', but it doesn't work either. Can someone kindly point me to the right place to look, so that I can understand what could be causing this?

Thank you, George

Check your flash driver. It seems to be misconfigured / not correctly adapted to your flash layout and/or flash chip types or sector sizes.
