Imported Atollic TS project to STM32CubeIDE. Project uses bootloader, but ignored in STM32CubeIDE

MFend · ‎2020-01-08

I built a bootloader and a project using the Atollic TS pdf How-to. The bootloader works well (at 0x0800 0000), and I can debug the program (at 0x0800 8000).

I imported the project to the STM32CubeIDE, but the project doesn't seem to start at the correct address.

When I used an *.ld file in which the project starts at 0x0800 0000, it seemed to work OK. but once I make space for the bootloader, and use address 0x0800 8000 in the *.ld file, I cannot manage to debug the project.

When I upload an image of the bootloader + FW to 0x0800 0000, the device works well.

In Atollic, I remember dealing with the Startup scripts - but I don't see this in the STM32CubeIDE.

Here's the script from TS:

# Default GDB command file (FLASH) for SEGGER J-LINK and STMicroelectronics STM32L451VE microcontroller.
 
# Set character encoding
set host-charset CP1252
set target-charset CP1252
 
# Set JTAG speed to 30 kHz
monitor speed 30
 
# Set GDBServer to little endian
monitor endian little
 
# Reset the chip to get to a known state.
monitor reset
 
# Set auto JTAG speed
monitor speed auto
 
# Setup GDB FOR FASTER DOWNLOADS
set remote memory-write-packet-size 1024
set remote memory-write-packet-size fixed
 
# Enable flash download
monitor flash download = 1
 
# Load the program executable
load		
 
# Reset the chip to get to a known state. Remove "monitor reset" command 
#  if the code is not located at default address and does not run by reset. 
monitor reset
# Set a breakpoint at main().
tbreak main
 
# Run to the breakpoint.
continue

I'm running on STM32L451VE

Below from the debugger console.

Why is there a reference to the following addresses?

Read 4 bytes @ address 0x08000EFC (Data = 0x0F04F01E)

Read 2 bytes @ address 0x08000EFC (Data = 0xF01E)

Read 4 bytes @ address 0x08000194 (Data = 0xFFFFFFFF)

Read 2 bytes @ address 0x08000194 (Data = 0xFFFF)

Until address 0x08008000 in internal flash is memory reserved and used for the Bootloader.

All program and data must start at 0x8008000

This is after I specified starting address

MFend · ‎2020-01-12

We are a team of FW developers. Until now, IAR was the IDE being used. Since we switched to STM MCUs, we want to incorporate the STM32Cube IDE as the IDE for all team members. Until this problem is solved, we cannot recommend the switch.

I would appreciate if someone can relate to this problem.

Thanks,

Mechi

How do I see entire conversation?

From the post at https://www.openstm32.org/forumthread2364 I understood another step, but it still didn't help the debugger to know where to start...

MFend · ‎2020-01-13

I upgraded to STM32CubeIDE 1.2.0 - still no change...debugger insists on starting at 0x8000efc!
