Eclipse qemu debug

HiFive Unmatched
1

Installed Eclipse from Third Party RISC‑V Tools (Software - SiFive).

Compile build in “Hello RISC-V World in C” example without error (see ‘compile output’ below).

Run as > 2 Local C/C++ application with error message but there is no output to Console

Debug as > 2 Local C/C++ application report error:
Error with command: gdb --version
Cannot run program “gdb”: Unknown reason

xPack GNU RISC-V Embedded GCC (riscv-none-embed-gcc) installed in
/Users/alain/Library/xPacks/@xpack-dev-tools/riscv-none-embed-gcc/10.1.0-1.1.1/.content/bin
and both riscv-none-embed-gcc and riscv-none-embed-gdb present in this folder

Is qemu installed by default in Eclipse from Third Party RISC‑V Tools ?
What is missing ?

Looks like you are using GNU MCU Eclipse, which I see has been renamed to Eclipse Embedded CDT.
https://eclipse-embed-cdt.github.io/
You might want to try asking there. They have their own forums. There is a link to the forums under Support which points here.

I want to run/debug without board, using risc-v emulation.
there is 3 Eclipse at www.sifive.com/software:
GNU MCU Eclipse IDE for C/C++ Developers
GNU MCU Eclipse RISC-V Embedded GCC
GNU MCU Eclipse OpenOCD
Which one achive my goal ?

4

Freedom Studio is the SiFive Eclipse release. I believe it contains qemu. But I don’t use Eclipse myself.

GNU MCU Eclipse is third party software. If you want support for that, you should probably talk to them.

Hi Alain,

To follow-up on Jim’s response Freedom Studio has 4 available SiFive qemu targets
as shown here:

FS-qemu_target
FS-qemu_target753×920 25.2 KB

To create your project, you’ll want to use the SiFiveTools - Create a new Freedom E SDK Software project menu.

As for the 3rd party links you referenced, it doesn’t appear to support a RISC-V soft target.

Regards,
Ralph

I am sorry to be unclear about qemu.
I want to compile, run and debug without the board.

The board will be used only from time to time to check the code written with Eclipse, board not connected.
The highlighted example state “… and uses board LEDs”

Is it possible to use Eclipse without board ? How ?

Than you.

7

If you choose qemu target then you don’t need a board. Please try it.

9

The version Freedom I have used is do not hold “qemu-sifive-s51”
I have try FreedomStudio but SiFive Mac FreedomStudio application is corrupted.
But I can see that application hold “qemu-sifive-s51”.
Do you know an other source where I can download SiFive Mac FreedomStudio ?

10

I don’t have a Mac so I can’t help with Mac specific issues.

11

Got the example from Freedom Studio:

s51
s51801×963 74.6 KB

There are 3 checkbox in “Select Target”. I use default setting, is it OK ?

There is no build error. The “Finnish” show a dialog with “Debug” button.
There is an error there:

debug_error
[see Apple console log below]

Can you help me…

Hi Alain,

We’re sorry you hit that issue. Could you please email your Eclipse log file to support@sifive.com?
The log file is located at <workspace_location>/.metadata/.log.

Thank You,
Ralph

13

Hi Alain,

It looks like there is a missing dependency (libvdeplug.3.dylib) that qemu is trying to load. Can you run this command in a terminal windows and paste the output here?

>ldd /Applications/FreedomStudio.app/Contents/Eclipse/SiFive/riscv-qemu-5.1.0-2020.08.1/bin/qemu-system-riscv64

Thanks,
Kevin

On Mac OS there is no ldd but there is an equivalent:

I got a similar problem with qemu-sifive-s51 on Ubuntu 20.10

2 - SiFive OpenOCD Launch

The first one do nothing, the second open the “Edit Configuration” window

This appears to be an issue with SiFive’s “Freedom Tools” software. If I’m understanding correctly, there is nothing specific to the HiFive Unmatched dev-board (and other dev-boards), so this discussion is off-topic for this channel (and the forums as a whole). In my opinion, the appropriate place for this discussion, as suggested in the error message above, is:
