Need Help Building PlatformIO

[chdgriff]

Using VS Code with PlatformIO and having trouble building for TFT35 E3 V3.

Just building results in:
Warning! Cannot find a linker script for the required board! Firmware will be linked with a default linker script!

I commented out the python script that was supposed to do this and specified board_build.ldscript.

My new environment configuration in paltform.ini is:

[env:BIGTREE_TFT35_E3_V3_0]
platform      = [email protected]
framework     = stm32cube
board         = STM32F103VC
upload_protocol = cmsis-dap
src_filter    = ${stm32f2xx.default_src_filter} +<Libraries/Startup/stm32f2xx>
extra_scripts = ${common.extra_scripts}
                ; buildroot/scripts/stm32f2xx_0x8000_iap.py
build_flags   = ${stm32f2xx.build_flags}
  -DSTM32F2XX=
  -DHSE_VALUE=8000000ul
  -DVECT_TAB_FLASH=0x08008000
  -DRAM_SIZE=48  ; Available RAM size in kbytes
  -DHARDWARE="BIGTREE_TFT35_V3.0_E3"
  -DHARDWARE_SHORT="35V3E3"
  -DTFT35_E3_V3_0=
lib_deps = ${common.lib_deps}
board_build.ldscript = buildroot/ldscripts/stm32f2xx_0x8000_iap.ld

But now platform io generates this error:
FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\chdgriff\.platformio\packages\framework-stm32cube\platformio\variants_remap.json'

I don't think I should have to modify the code to build for an included board. Is there anything else I need to configure first and how should I continue?

[teeminus]

I think the warning can be ignored. This project still used the original BTT build mechanism.

[teeminus]

Do you get the error with your modified platform.ini or with the "stock" one?

[chdgriff]

With my modified one. Without modifications I get this error:
Warning! Cannot find a linker script for the required board! Firmware will be linked with a default linker script!

And pio doesn’t build

[teeminus]

The unmodified one with the warning should build. At least for me it did the last time I compiled the firmware.

You could try again with a fresh checkout to have a clean state when compiling.

[chdgriff]

Reforked with a clean state and it doesn't build. Could you try to build on your end?

[teeminus]

Did a clean checkout and compiled the firmware for the 'BIGTREE_TFT35_E3_V3_0'. Works for me:

As you see, I get the linker warning as well. The firmware is placed in the .pio\build\BIGTREE_TFT35_E3_V3_0 folder.

If you can't get the build process to work send me your config tweaks and I will compile the firmware for you.
