This is a bad value. The configuration for group0 and group1 should
always be identical to be on the safe side. Use tool available at
to calculate your config.

How did you remake the kernel?

Something like this should do it (from the top directory):

make kernel && make images

If that doesn't help try a make clean in os/linux and then
make kernel && make images from the top directory

All the b0000008 are used to initialize the SDRAMs. All these values
are automatically generated from the value you enter. The last value
should be the same as you enterred.

Subject: SDRAM config


I have to set my own sdram config.
I made make xconfig in os/linux and entered my config value (0x01A00058)
into the field R_SDRAM_CONFIG.
After making the kernel i tried
boot_linux -F -p

this brought up a line like this:
etrax100boot ..... -setreg b000000C 09603737 -setreg.........

if i have a look into kernelconfig.latest i can find there my value. What's
going on?

Why are there so many -setreg b0000008 ? I would like to have b0000008 set
to 80409040.
