P1010 IFC Interface - Registers Configuration

fábiowalter — Fri, 20 Dec 2013 14:25:48 GMT

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.

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.
