5I25 custom Pinout was created by rene-dev
Hi,
I am using a 5I25 with a custom breakout board.
Currently I am using the PIN_R990x2_34 bitfile, as it is very close to my configuration.
Now I need more encoders, and based on the r990 pinfile I created the attached pinfile,
and built the bitfile using the current ISE version.
mesaflash --verify confirmed the bitfile was flashed.
the stepgens are still working.
However, the hostmot hal module fails to see the additional encoder:
[  757.086111] hm2: loading Mesa HostMot2 driver version 0.15
[  757.092833] hm2_pci: loading Mesa AnyIO HostMot2 driver version 0.7
[  757.092890] hm2_pci 0000:05:00.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20
[  757.092898] hm2_pci: discovered 5i25 at 0000:05:00.0
[  757.093128] hm2/hm2_5i25.0: config.num_encoders=3, but only 2 are available, not loading driver
[  757.093137] hm2/hm2_5i25.0: failed to parse Module Descriptor 2
[  757.093148] hm2_5i25.0: board fails HM2 registration
[  757.093165] hm2_pci 0000:05:00.0: PCI INT A disabled
[  757.093179] hm2_pci: probe of 0000:05:00.0 failed with error -22
[  757.664629] hm2: unloading

Is there any documentation on creating pinfiles?
Does the hal module need to know about the additional encoder?

Thanks,

Rene

Can you rename your new pin_xxxx.vhd file to pin_xxxx.txt
and post it here?

It looks about right

Did you cycle the PC power to load the new configuration?

I did powercycle.
Does it matter when I have modules in ModuleID that are not mapped to any IO? like the PWM.
I reduced the number of stepgens, and I can have up to 8, which should not be possible with the new configuration.
But mesaflash --verify confirms that the new bitfile is flashed.

It should not matter if you have unused modules (actually there are several modules that have no I/O pins) though for the PWM gen I would remove it since its just wasting space.

You can have as many stepgens as will fit, some parts of the stepgen will be optimized away if the output pins are not there, but since the stepgen position register is readable, the stepgen will still be created.

Note that mesaflash reads back the SPI flash chip on the card, not the FPGA configuration, you still have to power cycle (_NOT_ reset/reboot) the computer to load the newly flashed configuration in the SPI flash to the FPGA

I just rebooted, thought that would turn off the PCI power supply rail.
I am back in my workshop tomorrow and will try it again with proper powercycle(as in pulling the plug).

Thanks!

A reboot will cause a PCI reset but does not affect the power

The default 5I25 jumpering requires a power cycle to reload the FPGA configuration

yes, that worked. Thanks again.
Would it be possible to connect PCI reset to the FPGA reset?(just a stupid idea)
Just a couple of questions:
What are the "emptypin"s for, and how many are needed?
do they fill PinDescType up to a hardcoded limit?
Are there still addresses available for additional modules, or do I need to replace some when I create a custom module?
is there a hardcoded limit of 32 modules? because there are 32 NullTag modules.

What I need are a lot more I/Os, I was thinking a I2C/shift register/modbus port expander, which is transparent to the hal module.
I would like a portexpander in each switching cabinet of the mill.
The expanders do not need to be high speed for encoders or stepgens.
