sample/04-timer doesn't work on qemu or real pi

[MatthewRobertDunn]

I've compiled master branch of circle and compiled sample04 and I always get a crash

My environment is:

$ cat Config.mk
PREFIX = arm-none-eabi-
AARCH = 64
RASPPI = 3
DEFINE += -DNO_SDHOST
DEFINE += -DNO_CALIBRATE_DELAY
DEFINE += -DNO_PHYSICAL_COUNTER


$ aarch64-none-elf-g++.exe --version
aarch64-none-elf-g++.exe (Arm GNU Toolchain 12.2.Rel1 (Build arm-12.24)) 12.2.1 20221205

$ qemu-system-aarch64 -M raspi3b -kernel ./kernel8.img

Result in QEMU:

Uploading kernel8.img to a real rpi3 I get exactly the same result as qemu:

Looks like an older version of circle -- 45.2 tag works.....just not master branch

[Rene Stange]

Unfortunately I cannot reproduce the problem. sample/04-timer is working here on a RPi 3B and in QEMU. I can only guess, that there were stale object files in your project, after modifying the configuration in Config.mk, which caused this problem. You have to clean the whole project after changing Config.mk with makeall clean and also the sample's subdirectory with make clean. Tag Step45.2 is currently identical with the master branch.

[MatthewRobertDunn]

Thanks for this. I must of corrupted my environment somehow I guess, or perhaps make clean is missing some files?

Result:

[MatthewRobertDunn]

I did a clean checkout of the development branch and it works entirely fine, so I'm not sure how I polluted my original folder.

Might of been related to me changing from 32 to 64bit, not sure.

Sorry for the trouble :(
