I got an Olimex OKI-H5003 and tried to run
a simple program from the external SRAM to
toggle a GPIO pin at full speed.
I set HCLK to 30MHz and wrote 0x00 to RAMTYPE
in the RAMAC register. I saw the 30MHz clock
coming out from CKO pin, but the access time
of the XRAMCS_N pin was only 3MHz or so.
Is there anything I have to do to set up
the external RAM access timing correctly?
Cheers,
Yuri
