unable to reset E-STOP about linuxcnc-rio HOT 33 CLOSED

i need it anyway, i want to design a board and maybe use the up5k for it

thank you for investing so much time in this project

from linuxcnc-rio.

Very cool, thank you !

and i like your GUI, have to test it

from linuxcnc-rio.

strange if it's work with the python tool
if you changed the firmware, you have also to update the rio.h and recompile the hal-component.

from linuxcnc-rio.

aaaa, sorry, new update :) i have running 2 versions on my system, the one in the oss-cad-suite works fine.

You are running direct on the raspberry, i build it for amd64, sorry

from linuxcnc-rio.

okay got this and looks like what i had in config

but still no way to get the estop out :/ the other time that got followin errors was becouse i commented that on hal :/

just notice that i'm getting the same payload now

Bad SPI payload = 32303a30
Bad SPI payload = 32303a30
Bad SPI payload = 32303a30
Bad SPI payload = 32303a30
Bad SPI payload = 32303a30

should i build from pc and try... 😵‍💫

from linuxcnc-rio.

i have ordered an icebreaker board in china, hopefully in 2 weeks i will know more :)

from linuxcnc-rio.

yes it does

i was had an offset of 1M in the iceprog from another project and forgot to remove :_)

Just finished soldering the protoboard I'll try to get a video

from linuxcnc-rio.

does the ID change every time you try ?

i think this is a problem with SPI.
you can try to set the SPI-divider to 256 in rio.c:

//bcm2835_spi_setClockDivider(BCM2835_SPI_CLOCK_DIVIDER_256);
bcm2835_spi_setClockDivider(BCM2835_SPI_CLOCK_DIVIDER_128);

from linuxcnc-rio.

I think that is a bad setting in my board config clock speed, need to figure..

I tried changing that setting to 256 but this time got a different code in the message

from linuxcnc-rio.

ahh, and you need min. one Joint, one DIN, DOUT, VIN and VOUT until i have a fix for the hal-component

from linuxcnc-rio.

hello,

i could not get it to work
each time i press e-stop i get a different payload

I'll wait for the improvements.
Thank you so much

from linuxcnc-rio.

I don't know what I could improve at this point.
I think it is a connection problem, maybe too long cable or too high spi speed.

from linuxcnc-rio.

I'll check wiring

thanks

from linuxcnc-rio.

changing rio.c to
bcm2835_spi_setClockDivider(BCM2835_SPI_CLOCK_DIVIDER_256);
and recompile

does not help ?

from linuxcnc-rio.

Hello,

I tried soldering some headers to a PCB and got it like before, the qt app works but not linuxcnc,
I tried changing that option in rio.c and recompile with halcompile but got different payload errors

:)

from linuxcnc-rio.

:( hmm stange, can you send me your config please ?

from linuxcnc-rio.

sure here it is:

Hmm, looks ok , this should generate a working rio.h file

from linuxcnc-rio.

hello,

I noticed having one more zero in the clock speed... :(

but if I configure 3 DOUT the python tool moves one more that is not in the json conf :/

Thanks

from linuxcnc-rio.

I have update the tool a little bit, it's really bad but is helpful for testing :)

Ahh, Ok, so you have a clock of 12Mhz ?
maybe to slow for the fast SPI clock in the hal-component, but no problem (i hope):
"clock": { "osc": "12000000", "speed": "50000000", "pin": "35" },
the 'osc' ist you real clock speed and the 'speed' option is what you want to have,
this acitvates the internal PLL to push the clock speed up.

I think 50Mhz is ok, but you can also try 100Mhz

from linuxcnc-rio.

If I add the osc option i get this error

I'm very new to FPGA :)

Thank you

from linuxcnc-rio.

ok, thats also new too me, my oss-cad-suite is a little bit to old and iceppl is missing parameter (-p).
I have add a newer version of icepll (files/icepll) and add an exception to the firmware generator,
hope this will now work for this case.
Please try it again

Do you run the build on a workstation or on raspberry ?

from linuxcnc-rio.

I run he build from the pi itself

now got this one :)

i don't think it makes a different on PC

from linuxcnc-rio.

in binary, it looks like a speed issue:
0x32303a30 00110010001100000011101000110000
0x64617461 01100100011000010111010001100001

can you try to set the speed again:

• after building
• edit rio.h
• set: #define SPI_SPEED BCM2835_SPI_CLOCK_DIVIDER_2048
• halcompile --install rio.c

and restart linuxcnc

this will slow down the spi speed to under 1Mhz

from linuxcnc-rio.

and only to be sure, you have to stop the python tool if you running linuxcnc

from linuxcnc-rio.

yes yes only one app at time

from linuxcnc-rio.

:O awesome thank you so much!

from linuxcnc-rio.

don't worry I'm having lots of fun

from linuxcnc-rio.

I found the issue

may fault by having a offset in the iceprog tool

big face palm :=)

can I set this as fixed :D

Thank you so much :D

from linuxcnc-rio.

Wait what ?
does it work now ?

from linuxcnc-rio.

cooool !!!!
