Hello,
I would like to configure the field FTIM1 and FTIM2.
I am using a driver in the attachment file, that it was configurated the access to the memory with the .dtb file generating the lbc_teste.
I have the configurations to the LocalBus showed in the file xilinx.c, but only the register TACO change like I want.
The others registers like the TRAD_NOR, TCS, TCH, TWPH and TWP do not change the width in the oscilloscope.
I would like some help to resolve this problem, because I am accessing a device slower than the P1010.
Thanks,
Fábio Walter.
Original Attachment has been moved to: xilinx.c.zip
Please try to configure FTIMn in u-boot include/configs/P1010RDB.h.

Hi Yiping Wang !!!
With some changes in the driver, I change the signals' width.
Thanks for the help,
Fábio Walter.
