Hello!
VLYNQ REVID register does not appear on sprue14.pdf. I think it could be 0x0C000000 but according to sprue14.pdf 0x0C000000 address is 'Reserved'. At what address VLYNQ REVID is located? By the way I tried to monitor VLYNQ activity on DVEVM's R17 (VLYNQ_CLK) but I could only see the line going to low state when I set PINMUX0 register. This is what I do: 1.- Power on VLYNQ device (I get MDSTAT11=0x1F03) 2.- Modify PINMUX0 to enable VLYNQ and disable SCRUN (PINMUX0=0x8180AC1F) 3.- Write to VLYNQ_CTRL to set CLK and get VLYNQ out of reset (VLYNQ_CTRL=0x27B444) After step 3 it is supposed to be a 'negotiation' over VLYNQ bus, but I couldn't see any activity on VLYNQ_CLK (I choosed a 'serial clock output divider' of 7 to see the signal using an oscilloscope) Also VLYNQ_CTRL value (0x27B444) is a bit strange. Acording to sprue14.pdf, bits 6-3 are always 0, so it should be 0x7B404) I am using 0x0C000004 as VLYNQ_CTRL address. Has anyone tried to use VLYNQ? Am I writing to the wrong addresses?
