fuck i dropped my octopus and broke the sdcard on my way to testing bench.
but our first catch of the day -
Nucleo f446 doesnt want to reconnect to RPi5. after the first time i connect to linuxcnc, the nucleo doesnt reconnect unless i reset the board. otherwise i get bad spi data, will investigate further.
doesnt happen on rpi4
my little STM32F411 board works great every time for some reason
edit, tested with my second favorite octopus, and everything seems fine, i will chalk this one up to jankly nucleo
i like how fast this rpi5 is

Does it support BTT SKR PRO V1.2?Should I edit the source code and recompile the firmware for it or just use
BTT_407?BTT SKR PRO V1.2's MCU is STM32F407ZGT6
teamgloomy.github.io/skr_pro_1.2_pins_3_5.html
I tried to add BTT SKR PRO V1.2 to the custom_targets.json, mbed_app.json and edit main.cpp.After compiling it, I got the fiemware.bin.I wll test it when my RPI is delivered.

Greetings,
I have two nvem cards, I can't read all 80 pages of the post related to the implementation on linuxcnc, can you explain step by step the procedures of a short way to implement them on linuxcnc, in the shortest possible terms for those of us who have very little knowledge about programming. thank you

Best to start with
www.forum.linuxcnc.org/18-computer/44828...c300-ec500-cnc-board
The board you have is an STM based board, which was the first Ethernet board to be supported. So the early part of the above thread covers the development and firmware installation stuff.

Getting back to the topic of Remora SPI, I have pushed some updates to the repo to give command line options to specify the SPI number, CS number and frequency of the SPI interface for the RPi 5.
loadrt remora-spi SPI_num=0 CS_num=0 SPI_freq=20000000
Default frequency is 20Mhz, which is happily running on my Octopus, with Cakeslob's latest compiled firmware, without communication errors.
We'll need to update all the firmware to the latest. Thanks for your patience, but if there is a priority please let us know.

hey scott, with the ability to select the spi channel, do you think it possible to do multiple instances of remora using separate spi channels?

What would be the best 3d printer board to use with remora spi and raspberry pi 5 please? For k40 style co2 laser, so I dont need too many motors.
