IDROM IOPorts is 2 but MD IOPort NumInstances is 3, inconsistent was created by Cant do this anymore bye all

I have some firmware I'm writing for a RV901T, spartan 6 based,

Attachment not found

same card I was playing with for a SSREMOTE.

Setup has 2 ports with a 19 pins per port, modified mesaflash to recognise my board and all is good with the world.

The only issue I have is when loading the driver, based on the 7i90 EPP driver, I've had success modifying this driver to work with a 7c81 via EPP. The firmware I created was just 38 gpio pins. I saw some threads regarding the 7i93 & 7i98, but that didn't really help my situation. Any help would be great.

I'll include a dump of --readhmid via mesaflash.

The number of I/O ports in your pinout file does not match the number in your xxxcard file

Card file seems ok, the guts

Code:

package r01e_x16card is
		-- r01e_x16 card specific info
		constant ClockHigh: integer := ClockHigh90;
		constant ClockMed: integer := ClockMed90;
		constant ClockLow: integer := ClockLow90;
		constant BoardNameLow : std_Logic_Vector(31 downto 0) := BoardNameMESA;
		constant BoardNameHigh : std_Logic_Vector(31 downto 0) := BoardName9R01E;
		constant FPGASize: integer := 16;
		constant FPGAPins: integer := 256;
		constant IOPorts: integer := 2;
		constant IOWidth: integer := 38;
		constant PortWidth: integer := 19;
		constant LIOWidth: integer := 0; -- just txen on rev c cards
		constant LEDCount: integer := 2;
		constant	SepClocks: boolean := true;
		constant OneWS: boolean := false;

end package r01e_x16card;

Pin file has 32 Module_ID entries.
I have 38 pins defined followed by 106 empty pin entries.

Mesa flash seems to detect everything and has no probs writing to flash.

Does your pinout file specify 2 I/O ports?

That would be the on the IOPortTag line the value after ClockLowTag ? Which is NumInstances of the ModuleRecord ?

Sorry for such a glaring mistake.

(IOPortTag, x"00", ClockLowTag, x"02", PortAddr&PadT, IOPortNumRegs, x"00", IOPortMPBitMask),
