Re: [PATCH v2] docs/user: add docs for riscv/kendrytek210 BSP variant
I submitted a v4 patch for the user/bsps/bsps-riscv.rst page. I improved the instructions for running on Renode by providing a .resc file that would work, rather than modifying an existing script that was used to run Linux. This should work until I have some time to figure out why the 'SetSerialExecution True' keeps ticker from working. Given that defining CLOCK_DRIVER_USE_ONLY_BOOT_PROCESSOR also works, this seems like a race condition between RTEMS and renode. I don't notice this on any of the physical boards I have tested. I don't understand the implications of telling the clock driver to only use the boot CPU, so I would prefer to leave that alone for now.

Hi Alan, We have a standard for the documentation source: https://git.rtems.org/rtems-docs/tree/README.txt#n469 Please note the line length. That can be relaxed when pasting in output but we need the written text to be within the bounds.

Re: [PATCH v2] docs/user: add docs for riscv/kendrytek210 BSP variant
Hi Chris, Sorry I should have read that and formatted my changes correctly. I submitted a v5 patch, but as I sent it, I realized that there are a couple of places where the RTEMS version macro can be embedded rather than hard-coding "6". I should have taken more time and avoided flooding the mailing list with extra traffic. - But I'm much better at this process now :) Later today, I'll send a v6 patch with the rtems version macros.

Re: [PATCH v2] docs/user: add docs for riscv/kendrytek210 BSP variant
Thanks Alan for investigating this issue and following up with the updates. It's fine to leave it for now, perhaps even report it to Renode if we think it's a problem with their simulator or something.

Update on K210/ticker on Renode: If I define CLOCK_DRIVER_USE_ONLY_BOOT_PROCESSOR in the RISC-V BSP, ticker works on the unmodified .resc file.

Re: [PATCH v2] docs/user: add docs for riscv/kendrytek210 BSP variant
Hi Hesham, I found a difference between the .resc file I use to run single tests and the .resc file that the renode-test uses. The resc file where ticker.exe fails has this extra statement: $ex='machine SetSerialExecution True' If I comment that out, ticker runs on Renode. I couldn't find that in the documentation, so I'm going to have to search the renode code to see what it does. I'm pretty sure I used to run ticker.exe by itself without commenting out that line. It's odd because a number of other examples work with the statement like smp08.exe, unlimited.exe, hello.exe. For reference, my renode-test setup for the K210 is here: https://github.com/alanc98/k210-rtems-test Note that if you run this, the rki test will fail unless you remove the last test or build an RKI image for the k210: https://github.com/alanc98/rki2/tree/rtems6 Alan On Sat, Apr 1, 2023 at 6:13 PM Alan Cudmore wrote: > Interesting - I get the same error when I run ticker on renode now.

Re: [PATCH v2] docs/user: add docs for riscv/kendrytek210 BSP variant
Interesting - I get the same error when I run ticker on renode now. I just tried it on a board and it works. It also still passes the renode-test that I run, which includes ticker ticker along with a dozen other tests. I'll look into why this does not work right now.
