Mesa 5i20 Smart Serial supporting Firmware

it doesn't run

insmod: error inserting '/usr/realtime-2.6.32-112-rtai/modules/linuxcnc/hm2_pci.ko': -1 Unknown symbol in module

Can you look at dmesg and see what the actual fault is?

in PIN_SVSS4_4_72.vhd, change
SSerialNumRegs, x"00", SSerialMPBitMask
to
SSerialNumRegs, x"10", SSerialMPBitMask


and in Top9030HostMot2.vhd change

-- InstStride1: integer := 64; -- instance stride 1 = 64 bytes = 16 x 32 bit registers
InstStride1: integer := 16; -- instance stride 1 = 16 bytes = 16 x 32 bit registers

to
InstStride1: integer := 64; -- instance stride 1 = 64 bytes = 16 x 32 bit registers
-- InstStride1: integer := 16; -- instance stride 1 = 16 bytes = 16 x 32 bit registers

WOW! It's ALIVE!!!!

Now the main problem is connecting 7i44 and 7i71

loadrt hm2_pci config="firmware=hm2/5i20/SVSS_2.BIT num_encoders=4 num_pwmgens=4 num_3pwmgens=0 num_stepgens=0 sserial_port_0=00000000

How this line should look like?

That looks OK but I think the bitfile is wrong I think you want PIN_SVSS4_8_72.vhd as the pinout file for a 7I44...

(with 7I44 on P4)

PIN_SVSS4_8_72.vhd should not need any changes

PIN_SVSS4_4_72.vhd was busted because its a weird pinout and has
probably never been tried with LInuxCNC

I've already figured it out ) thanks to "mentor"



in top9030Hostmot2.vhd
uncomment --use work.PIN_SVSS4_8_72.all; and comment previous

Is it right?

yep

SVSS4_8_72 firmware installed ( i called it SVSS_3)

7i44 is connected to 5i20 (on p4,)

7i70 is connected on 7i44 0 port

I've tried this

loadrt hm2_pci config="firmware=hm2/5i20/SVSS_3.BIT num_encoders=4 num_pwmgens=4 num_3pwmgens=0 num_stepgens=0 sserial_port_0=00000000 "

and this

net siGGnal hm2_5i20.0.7i71.0.1.output-00

got this
Pin ' hm2_5i20.0.7i71.0.1.output-00' does not exist

before you worry about pins I would check the 7I71 LEDs to verify that
1. You have field power (yellow LED on 7I71)
2. You have a blinky green light on 7I71 when you start LInuxCNC
3. Pretty sure he signal name would be hm2_5i20.0.7i71.0.0.output-00
since it is on sserialport 0 channel 0
