migrating from v2 to v3

[ralph]

I am working to update a working ChibiOS project to the current version. Updated the makefiles to use the new rules file, etc. and worked through most of the errors. However, I have a couple I am having trouble chasing down:
/home/ext/ChibiOS_18.2.1/os/common/startup/ARMCMx/compilers/GCC/rules.mk:238: target 'build/obj/crt0_v7m.S' doesn't match the target pattern
/home/ext/ChibiOS_18.2.1/os/common/startup/ARMCMx/compilers/GCC/rules.mk:238: target 'build/obj/vectors.S' doesn't match the target pattern
/home/ext/ChibiOS_18.2.1/os/common/startup/ARMCMx/compilers/GCC/rules.mk:238: target 'build/obj/chcoreasm_v7m.S' doesn't match the target pattern

Can anyone point me to where those files get selected and set, and any suggestions on fixing the errors?

Thanks.

Hi,

It does not find those files, check your CHIBIOS variable in makefile, it must point to the root of a ChibiOS source tree.

Take makefile and configuration files from the version you want to use, trying to adjust old files is usually a bad idea.

I am using the .mk files from the new version, and update the paths in the ChibiOS makefile. I am running a Makefile for my project, I have updated all the paths to the new version.

[Giovanni]

Hi,

Those files are included by this line:

Code: Select all

# Startup files.
include $(CHIBIOS)/os/common/startup/ARMCMx/compilers/GCC/mk/startup_stm32f0xx.mk


Look inside that .mk file.

I started over with the closest example, verified that built, then added back in my project specific paths, etc. Unfortunately I am still having the same issue. Output from running make with the debug option suggests that these files do build after this error, but not correctly, it keeps retrying but not succeeding.

I did verify that startup_stm32f4xx.mk is present and accessed from the correct directory.

I would appreciate any guidance on tracking down this error.

The last several lines from the debug:

For those who may find this thread in the future or are having similar issues:
The crt0_v7m.S,vectors.S and chcoreasm_v7m.S files were not building because the processor type variable was not updated to comply with Chibios5.0.0 requirements. I needed to add

Code: Select all

#define STM32F427xx

to my board.h file.

[Giovanni]

Board files are generated, you should not need to edit those manually.

Anyway, it is correct, board.h needs to define the device identifier.

Giovanni

[ralph]

Where are the board files generated? Maybe I fixed a symptom rather than the root cause.

I should also note I am using a custom designed board, it is not one of the standard demo boards.

The current issue is that I am getting errors from hal_lld.h such as:

Code: Select all

#error "STM32_PLLVCO outside acceptable range (STM32_PLLVCO_MIN...STM32_PLLVCO_MAX)"

It does not seem to be picking up the clock definitions in mcuconf.h

[Giovanni]

Hi,

Look into the board directories, you should see in there a cfg/board.chcfg file, it is an XML describing the board. Board.c/.h/.mk files are generated from that xml using a functionality in ChibiStudio: select the .chcfg file and click on the button that appears in the toolbar.

It can also be done from command line but it is more complex and requires some setup.

Thanks, that's helpful.

Making good progress, I'm getting link errors now

Any simple/easy/known fix to C++11 system call issues? Read the thread on the wrapper, but it sounds like that was rolled into the current version.
