older 5i25 with 7i76 not working with Linuxcnc 2.9.8

Hi Guys,

tried to update a system with Mesa 5i25/7i76 kit, running well on wheezy 2.7 to 2.9.8.

The hostmot driver seems to have problems to see the cards. Maybe they are too old? (10-12 Years)
lspci shows a device called "DPIO 2718:5125", mesaflash does not find the 5i25
pncconf seems to see the cards and uses the correct config and mesa tabs.
But Linuxcnc doesn't start because of unknown pins(?) in the hal file
I have attached hal and ini... (See comments in hal where the wrong entries are)

Do you experienced guys see whats wrong here?

Thanks in Advance and best Regards
Stefan

Can you post whet the exact error is?

If mesaflash does not find the card, that seems more like a hardware/BIOS issue

Also:

setp hm2_5i25.0.dpll.01.timer-us -50
setp hm2_5i25.0.stepgen.timer-number 1

Will fail on a 5I25 that does not have a DPLL module,
so you might try commenting those lines out.


 

you helped me out, thanks a lot!
I wasn't aware about the dpll module with/without...

The machine is working now but mesaflash doesn't see the 5i25 anyway,
but doesn't matter for me, just wondering...
 

Some BIOS's disable memory access in PCI peripheral cards
LinuxCNCs hm2_pci driver re-enables them. This is the likely
cause of this issue.

You _may_ be able to access the card with mesaflash after running LinuxCNC
but this is not necessary unless you need to change your daughtercard setup.
