Hi Greg & Bin,
I have used 2x32M SDRAM on my board, the loader did chip select well and I think it is not neccesory to do chip select again
in kernel, is that right?
When I used 128k ramfs image, the system will boot well and work, but sometimes it hangs up in the situation using
memory.
I think, as Greg said, I have my SDRAM working in unormal status. I cannot allocate memory larger than 1M enven I have choose
the option allocate large memory and I cannot use static array larger than 500k in my program. Also, when I tar a tarball with size larger
than 500k, the system hangs......
Forgive my poor English and this is my first time using mailist.
Would you plese told me how to "Re" your mails as you do show in the thread tree and how to quot your mail content? ^_^
Thank you very much!
Best Regards,
Will Huang
not sure if I remember it right, seems the chip select was done in boot
loader and uclinux does not do this in kernel.

f you use the 128k ramfs image, but with the memory size set to
