Octopus Pro 1.0.1 (H723) and SPI3

General Discussion
1

Hello,
I went from a octopus pro with 429 chipset to an octopus pro v1.0.1 with a h723 chipset.
My config was transferred without any problem but only for one section.
It seems that SPI3 is not available in the firmware for h723, I get the following error " Unknown spi_bus ‘spi3’ ".
Has this been renamed ? all I can see in the firmware file is a reference to spi3a and spi3 is absent.

this is the portion of my config causing the issue:

cs_pin: PA15
spi_bus: spi3

Thanks for your guidance.

Not sure if you got this sorted, I had a look at the klipper.dict file for the h723 board and it looks like the spi_bus you want is spi1a(“BUS_PINS_spi1a”:“PB4,PB5,PB3”) . Those pins correspond to the board pins shown on the btts colour pinout pdf (which also shows PA15 as the CS pin). So definitely not the spi3 that the f4xx pro boards use.

So…

cs_pin: PA15
spi_bus: spi1a
