.pioinit:15: error while trying to debug

I get this error, as I’m trying to debug my SMT32F103VCT6 MCU. I’m using STLink-V3. I have tried providing as much information regarding my setup in the initialization file. I have seen this error (or similar ones) are quite common, but haven’t found a solution based on other answers.

This is the complete debug log from terminal.

.pioinit:15: Error in sourced command file:

This is the initialization file I’m using:

platform = ststm32
board = genericSTM32F103VC
#framework = stm32cube                ; can't use, provide custom flags
extra_scripts = SetCompilerPath.py
platform_packages = toolchain-armcc@symlink://C:\Keil_v5\ARM\ARMCC\bin
board_build.ldscript = "PCV2-SES.sct" ; previously it was GCC "src\STM32F103VCTx_FLASH.ld" (which is indirectly supported by ARM via link options)
build_flags = 
upload_protocol = stlink
debug_tool = stlink
#upload_command = ${platformio.packages_dir}/tool-stlink/st-flash write $SOURCE 0x8000000
board_build.mcu = stm32f103vct6

The address for the ER_RO section seems extremely low, Flash is at 0x08000000, RAM is at 0x2000000. 0x8000 seems like bootloader memory region? What’s the content of the scatter file that decides the load addresses?

I have managed to resolve this issue another way. Not sure what I did, but I modified/removed some build flags and now I’m able to build and debug without this issue.

Here is my scatter file for this project, just in case you want to check it out. But I really think everything is okay here.

  ER_IROM1 0x08000000 0x00040000  {  ; load address = execution address
