Remora - Rpi Software Stepping Using External Microcontroller via SPI

Hi cakeslob, 

The Octopus v1.1 does have the bootloader offset "-DVECT_TAB_OFFSET=0x8000" in the Marlin ini file. These are correct and the starting address as per the Bigtreetech bootloader info summary.

Not sure what's going on with your build environment as selecting the OCTOPUS or SKRV2 target should not be looking inside the SKRV1_4 target directory, this is why the Mbed build system is handy. Are you using Mbed Studio or CLI?

The repo is an image of my build environment (less mbed-os) so strange it's not working....

 
STM32F Discovery dev board uses the same part # STM32F407VGT6 as the SKR V2

Im using studio, ive compiled the stm32 repo just fine. I also find it strange, I just download the git, open a workspace in remora os5, and download the libraries within studio, says its 5.15.0. Select target, SKRV2 or OCTOPUS, and build. The file LPC17xx.h is there under targets/nxp/device . Says everything is up to date for mbed studio


this is the full output, I was just wondering if there was some secret

MODDMA lib

edit, ok I was doing something with the MODDMA lib that was messing it up

Hi, the MODDMA library is already included in the repo in the correct location within the TARGET_SKRV1_4 directory. No need to import it again, which will put in the root directory and in the compile path.

Thank you for your help and patience. Yeah studio was saying i should "fix" the mbed-os and moddma lib. That explains why the stm32-repo worked and the main didnt.
How do I go about debugging this octopus? something like FTDI ,stlink or JTAG?? Can we hook these up USB like the official mbed boards and debug within studio? Ill break what ever I have to...
What I do know
I have reset pin on PC_15 in my config
Firmware loads and makes a cur file
Leds look like they are loading firmware and acting proper
12v power
Bad SPI payload = 0
No output on the serial
Memory does not look corrupted and bootload/firmware are on the correct address lines
SKR2 for reference, works on my setup.

look if ur connected to the right spi port.
