EMIF connector on DSK6713

Started by eewizard_1 April 4, 2004

Hello All

I'm new to using the TI DSP's and have a Spectrum Digital 6713 DSK.
I have a daughter board that has some ADS1626 1.25MHz A/D chips,
among other things, that I have set in memory at 0xa000... for CE2.

Try as I may I can't get the DSK board buffers between the DSP and
the daughter card connectors turned on. I can see the CE2 pin doing
the pattern I expect on one side of the LVHT16245 but not at the
connector.

I have written to the low 2 bits of the DC_REG on the CPLD and also
pulled down pin 78 (DC_ARDY) on the connector but can't get the CPLD
to turn on the buffers.

I would also like to play with the memory timing and have changed
what EMIF_CE2 is set to in init_emif() section of the .gel file but
no change on timing.

I'm sure there are some easy tricks hidden in the docs but I guess
I'm getting old. Any of you that made a daughter board has solved my
problem so could you please pass on a few pointers to me.

Thanks much, Al
