Hey,

I have a problem when I use the toolchain after installation.
Although the make check cmd says:

Toolchain check OK

When I actually try to: make clean_all install in the demo_blink_led directory I encounter an error:

[ucycg@itiv-work5 demo_blink_led]$ make clean_all install /home/ucycg/Programme/riscv/bin/../libexec/gcc/riscv32-unknown-elf/12.1.0/cc1: error while loading shared libraries: libmpfr.so.6: cannot open shared object file: No such file or directory make: *** [/home/ucycg/Dokumente/neoipe/ext/neorv32/sw/common/common.mk:182: main.c.o] Fehler 1
As I already noticed I installed the the whole toolchain in /home/ucycg/Programme/riscv instead of /opt/riscv
when I ran a grep cmd I realized that there are a lot of files where this /opt/riscv path is specified in some form. Could this be related to my problem? Also for example in the gcc configuration sysroot=/opt/riscv/riscv32-unknown-elf is specified
Do you have any idea how to change that in a convinient way or is this even possible?

I am working over a remotedesktop access to server at my uni since I don't have sudo rights I installed it in my own directory instead of /opt/riscv since getting someone to create this for me would be probably a pain.

Thx in advance and kind regards

I'm currently running the NEORV32 Code via Cadence xcelium and was able to simulate successfully the blinky LED example via the application image.

Is there anything on the Github that lets me test the bootloader by sending a code example via uart to the processor and all of this inside Cadence Xcelium? My idea so far would be to write my own UART TX module as part of a testbench somehow that transmits the Code to the CPU with the bootloader code.

If there is anything like this already existing I would be glad to know that or if you think there is a better idea to do what I want to do.

The final goal for me is to do a physical chip design with the NEORV32

Hi Stephan,

your Prebuilt GCC is a real big deal. It makes the compile of source code easily. But whenever you are in need to build your GCC from scratch it would be very helpful to store also the used commit for build in your table:

This table could for instance modified to:

Could this suitable?

Thanks and BR,
Andreas

I've been trying to add some custom instructions to this prebuilt toolchain (rv64imc-3.0.0), which requires me to find opcode definitions in riscv-opc.h and riscv-opc.c.

I've found that if you build the original toolchain, the above files could be found under binutils/include/opcode and binutils/opcodes/riscv-opc.c, respectively.

However I've been struggling to find the binutils folder in the downloaded/extracted toolchain here, any help regarding where I might be able to find the folder or something that serves similar functionality?

Hi
When I tried using prebuilt binaries in Mint, I got this error. stdint.h no such file or directory.
Thanks

When I follow the instructions here to build the neorv32 "hello world" example, the build fails with the error extension 'zicsr' required:

rweeks@dev-compiler-build:~/projects/neorv32/sw/example/hello_world$ make USER_FLAGS+="-DUART0_SIM_MODE -DUART1_SIM_MODE" MARCH=rv32imc clean_all sim
../../../sw/lib/include/neorv32_cpu.h: Assembler messages:

../../../sw/lib/include/neorv32_cpu.h:343: Error: unrecognized opcode `csrc 836,a0', extension `zicsr' required

According to this section of the neorv32 docs, the zicsr extension is mandatory and can't ben enabled/disabled, so I'm not sure what's gone wrong.

Reverting to the 4.0.0 toolchain fixes the problem.

Why is rv64imc-3.0.0 marked as deprecated? Is is still usable?
