I have a DE1-SoC (Cyclone V) board where I am trying to get timer interrupts to work on the HPS. I found an example in the Intel FPGA University Program called "interrupt_example", and when I run it on the Intel FPGA Universioty Program, it runs perfectly.
Now I want to transfer this project to ARM DS, but I cannot get it to work because everytime when I am trying to write to the interval timer at address 0xFF202000, the debugger won't proceed. When I try to look in the memory of 0xFF202000 in ARM DS, I also cannot see anything.
I am using the same compiler (GCC C 4.7.3 arm-altera-eabi) and I tried to use the same compiler arguments:

I also tried to use the same preloader, but this does not work out when I am writing the debug script. I am not sure if this is the problem. If this is actually the problem, I would appreciate it if someone can help me writing another debug script, because ARM DS is giving me problems when I try to use u-boot-spl.de1-soc.srec as a preloader.

The disassembly of the code where the 0xFF202000 is being written also looks identical:

I tried everything which I could think of now. I really hope someone can help me. Thank you in advance.
Edit:
In the mean time, I found that when the program tries to write to 0xFF202000, it enters an endless loop in assembly. I am not really familiar with assembly, so I am not sure why this happens.

I'm trying to cross-compile an llvm-ir file to assembly, or better generate an object file, for an ARM Cortex M4 microprocessor using llc compiler.
Which are the parameters that I have to specify in order to do so?
I have tried with this command
llc -mtriple=armv7m-eabi -mcpu=cortex-m4 file.ll -o file.s
It doesn't throw any error but the assembly code generated is still for an x86 machine.
In particular, trying to compiling with random parameters, e.g.
llc -mtriple=randomwords -mcpu=cortex-m4 file.ll -o file.s
It goes smooth, producing an assembly code for the x86 machine. It ignores what I specify.
I found a solution, or better a work around to this problem.
Instead of using directly llc, first I've obtained the binary code through this command
llvm-as file.ll -o file.bc
An than I used clang to crosscompile and obtain the object file for ARM Cortex M4 using this instruction
clang --target=arm-none-eabi -march=armv7e-m -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb -nostdlib file.bc -c -o file.o
The -c is used to compile only.
It is also possible to obtain the assembly code by using the following command line
clang -S --target=arm-none-eabi -march=armv7e-m -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb -nostdlib file.bc -o file.s
llc (not sure about prior to v9) seems to only care about the architecture.
I can cross compile and link with the following script (for a RPI running Linux):
#/bin/sh
llc-9 -march=arm -float-abi=hard -O3 -filetype obj $1.ll -o $1.o
~/devel/musl/musl-cross-make/output/bin/arm-linux-musleabihf-gcc -mfloat-abi=hard -static $1.o -o $1
llc --version will show the available architectures
Try the following for your case (or use a more specific architecture if it is in the list):
llc -march=arm -mcpu=cortex-m4 -filetype obj file.ll -o file.o
If someone would please tell me what kind of syntax the following file is?

While building my project with Eclipse Arduino I am having issues with the Makefile that gets created from this file in arduinocdt which I am trying to debug.
There is an issue with macro expansion from ARDUINO_BSP_VERSION (solved)
Another issue is with flashing my built firmware.
The file is in fact a Java .properties file and the 3rd party Hardware format specification to be used in Arduino IDE and Eclipse Arduino CDT.
I am trying to build DBD::Sybase on Debian machine, but I am running into a problem. The problem is, BFD (GNU Binutils) 2.21.1 internal error when linking the program. Please help me resolve this.

As #jww pointed out, the issue was the older version of binutils and gcc. I just edited the generated Makefile in Sybase base directory to point to newer versions of gcc and binutils. FYI, I the versions that worked are "gcc version 6.3.0 " and "GNU ld (GNU Binutils) 2.28.1"
this is driving me bonkers.
For parallel make builds (-j), you're supposed to be able to synchronize the console output. Here is ref:

The --output-sync option is only available in GNU make 4.0. Also, in your case you should use:
--output-sync=target
or
-Otarget
But this won't work with version 3.82.
