Summary: kernel with CONFIG_BFIN_KERNEL_CLOCK fails to boot on bf526 ezbrd 0.2.

Details:

kernel with CONFIG_BFIN_KERNEL_CLOCK fails to boot on bf526 ezbrd 0.2, while with the same u-boot and kernel, it can boot up on another bf526 ezbrd 0.1 board.

Enter 'help' for a list of built-in commands.

This issue may related to an old bug 4615, sincee it is ezbrd, and the other ezkit boards looks booting up ok with CONFIG_BFIN_KERNEL_CLOCK item on , I open this tracker.

Follow-ups

--- Graf Yang 2009-06-17 06:24:54

This bug is caused by SDC parameters not fit for it's SDRAM chip.

ADI website

(http://www.analog.com/en/embedded-processing-dsp/blackfin/BF526-EZBRD/processors/product.html)

says it use MT48H32M16LFCJ-75(VFBGA 54ball 8mmx9mm).

On 0.1 board, it's a VFBGA 54ball 11mmx9mm chip. Kernel boot OK in a variety of

system clocks.

There is a 8mmx9mm chip on 0.2 board.

But it fails if reprogram the sclk.

I found if increment the SDRAM_tRAS by 1, both the boards will boot at various

sclks.
