Mesa 5i22 + 7i29 + 7i52 custom firmware

I tried to compile a new firmware for the 5i22 because I have to combine two 7i29 + one 7i52, so I made a new .vhd file with a guess for what I have to include after reading other files. Unfortunately the generated .bit file does not load and dmsg reports "hm2/hm2_5i22.0: IDROM IOPorts is 4 but MD IOPort NumInstances is 3, inconsistent firmware, aborting driver load" . I compiled with ISE 9.2.

I guess I'm doing something wrong

Maybe Peter could have a look at the vhdl source and tell me what is the problem?

I have attached the .vhd file


Thanks,
Kostas

Oops, I see now that the file was not attached, maybe because of the extension? Same as .txt ..

at least this line is in error:

(IOPortTag,x"00",ClockLowTag,x"03",PortAddr&PadT,IOPortNumRegs,x"00",IOPortMPBitMask)

the 0x03 (number or I/O ports) should be 0x04 for a 5I22

Thanks Peter. Would it be easy for you to make a new configuration for this? I thought I might give it a try and build one myself, but now it fails with different errors ..

I will try and get to this some time this week

That would be very helpful, thanks!

Here is the edited pinout file and bitfiles for 1.5M and 1M 5I22s

Note that I used multiplexed encoder for all encoders since I'm not sure
if the driver version you have supports mixed encoder types.

This results in somewhat odd encoder numbering:
PHYSICAL HAL
7I29 ENC0 ENC0
7I29 ENC1 ENC2
7I29 ENC2 ENC4
7I29 ENC3 ENC6

7I52 ENC0 ENC8
7I52 ENC1 ENC9
7I52 ENC2 ENC10
7I52 ENC3 ENC11
7I52 ENC4 ENC12
7I52 ENC5 ENC13

It's working! Many thanks Peter!

Peter, I tried to compile a modified version of the vhdl file you gave me because as it turns out I need a firmware with two more pwms and encoders for one more 7i29 I'm about to order soon. I used the tree from git://git.linuxcnc.org/git/hostmot2-firmware.git and your modified vhdl file and compiled with ISE 10.1, but I can't get results.

Firmware compiled succesfully but I get an error: "hm2/hm2_5i22.0: The bitfile contains Smart Serial modules for a firmware revision < rev22. This Driver now requires rev22 or newer firmwares"

Can you tell me what I should do? I don't want to bother you all the time with firmware customizations if I can build them myself.

Thanks in advance.

I would download the source from mesa, (in 5i20.zip)
use the fivei20 project file and go from there
