Error compiling SKR 2 envs

[goeland86]

I'm a newbie with grblHAL, so apologies if I missed something in the documentation I should've seen.

I set up a new environment for the SKR 2 with TMC2209s as follows:

[env:btt_skr_2_tmc2209]
# Untested and might not boot.  Please report issues at:
# https://github.com/grblHAL/STM32F4xx/issues
board = genericSTM32F407VGT6
board_build.ldscript = STM32F407VGTX_FLASH.ld
build_flags = ${common.build_flags}
  # See Inc/my_machine.h for options
  -D BOARD_BTT_SKR_20=
  -D HSE_VALUE=8000000
  -D USB_SERIAL_CDC=1
  # Boot loader offset (32K)
  -D VECT_TAB_OFFSET=0x8000
  # TMC2209 stepper drivers
  -D HAS_BOOTLOADER
  -D TRINAMIC_ENABLE=2209
lib_deps = ${common.lib_deps}
  eeprom
  trinamic
lib_extra_dirs = ${common.lib_extra_dirs}
# Upload is not supported for this board since BOOT0 is tied to GND.
# With the default boot loader, you must deploy new firmware by copying
# .pio/build/<env name>/firmware.bin (produced by `pio run`) to the SD card.

When I build (using PlatformIO in VSCode), I get the following error during compilation (full log truncated for clarity).

Out of curiosity, I tried the TMC2130 version, just to see if that builds. It seems not.

I would appreciate any input on how to resolve this. The WebBuilder also disables any EEPROM option for the SKR 2 board, which has proven frustrating when trying to set up my router.

Thanks for any pointers to resolve the issue.

It builds with both the STM32CubeIDE and the WebBuilder so must be something wrong with your platformio.ini.
Here is the WebBuilder generated platformio.ini for you to compare with:

Your provided platformio.ini test file works - and I was using the default from the project for SKR2.

May I kindly suggest that the SKR2 definitions in the provided platformio.ini file from the project re-use the provided values listed above?

I'm happy to create a PR to do so if it would be helpful.

I'm glad a found this issue. I was working on a custom board and basing it around the SKR2 and was stumped why none of those would link properly.
