[Solved]7i76e missing field IO with custom firmware

Hi

I have a similar problem to www.forum.linuxcnc.org/39-pncconf/38078-...io-ports-pins-solved but mine appears to be firmware related. I've built a custom firmware to include a PWM and PkUART which is all working fine but with this firmware loaded the field-io pins, such as hm2_7i76e.0.7i76.0.0.input-04, don't show up when loaded up. If I revert to the original firmware,which I think is 7i76e_7i76x1D.bit, all is fine and the pins are back.

I wasn't sure which was the base source code for this and I based my new firmware on hostmot2/source/PIN_7I76x1D_51.vhd - was this the correct choice - and if so - anyone know what I've messed up ?

Many thanks

Matthew

I know I'm not helping but what is planned for the UART?

What does mesaflash --readhmid show?

Hi - this is the application - a remote display board and I'm also working on a remote control quill controll for drilling.

Hi

Attached are the dumps from mesflash as shipped, and with my firmware - I'm using the linuxCNC 2.9.0-pre0-2304-g424c1cb59 version to correctly identify the pkUART tags but I think mesflash is an older version so has them as (unknown-gtag-27) and (unknown-gtag-28).

Thanks

Yeah, there's no sserial module in your configuration so no 7I76E field I/O

Thanks -

I didn't realise they were co-dependant, I wanted to re-purpose the pins on the RS422 interface (TB3 - 16 and 18) as 5V pins for the TTL pkUART module as 5V pins are a bit short supply. Is it sufficient just to have the module present to get the field-IO definitions or do I have to keep the RS422 as original ?

Matthew

They are not co-dependent but you need to leave the sserial module installed
and the sserial pins that connect to the field I/O with their original definitions.

PCW made a 7i76e with PK_uart support here.

Not sure if that will help
