<pre>Hello,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I tried to experiment a bit with the riscv BSPs.<o:p></o:p></pre>
<pre>I could run them using the SIS simulator, but failed with qemu.<o:p></o:p></pre>
<pre>Regarding qemu I found this ticket:<o:p></o:p></pre>

<pre><o:p> </o:p></pre>
<pre>In one mailinglist thread (from 2018) someone said it worked with a current master version of qemu.<o:p></o:p></pre>
<pre>I have compiled qemu-5.1 and qemu-5.2-rc2. Does anyone know if those version have the necessary patches included?<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Then another source of error could be the command line parameters I used:<o:p></o:p></pre>
<pre>qemu-system-riscv32 -nographic -machine virt -m 2G -bios none -nographic -net none -serial stdio -monitor none -kernel ticker.exe<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Does someone have an example for a working set of command line options?<o:p></o:p></pre>
</blockquote>
<pre>Which BSP did you build and how did you build it? Can you try with -bios ticker.exe and discard the -kernel option? Did you try RV64?<o:p></o:p></pre>
</blockquote>
<pre><o:p> </o:p></pre>
<pre>I used the griscv BSP. If I read it correctly, it should be a rv32imafd processor. I built the BSP from current master and used the waf build system to build it.<o:p></o:p></pre>
<pre>I also just tried (with qemu-5.2.0-rc2) the following command using bios instead of kernel:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>qemu-system-riscv32 -nographic -machine virt -m 2G -nographic -net none -serial stdio -monitor none -bios /tmp/riscv/rtems/build/riscv/griscv/testsuites/samples/ticker.exe<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I still don't get any output. It might very well be that the serial or monitor configuration is not correct. These options are always a bit mysterious to me.<o:p></o:p></pre>
<pre>FWIW if I use "-serial stdio -monitor none" I can close qemu with Ctrl+C. If I use "-serial mon:stdio" Ctrl+C does not work.<o:p></o:p></pre>
<pre>Using qemu-system-riscv64 doesn't change anything.<o:p></o:p></pre>

<p><o:p> </o:p></p>
<p>The griscv bsp only works with sis, as it uses leon3/grlib peripherals. To run on qemu, you need to use the riscv/riscv bsps, e.g. rv32imafdc or any other in rtems/bsp/riscv/riscv/config.
<o:p></o:p></p>
<p>Jiri.<o:p></o:p></p>
<p>PS. I plan to add "pure" riscv support to sis, once I find the proper device-tree definitions for the bsps ...<o:p></o:p></p>
