Error with Keil RTX5 tutorial

Actually, I think you are mixing up some different operating systems:

- os_Error was the error handler in our Keil RTX4, but with different parameters. See www.keil.com/.../group__RTX__Global__Functions.html

- The error handler of Keil RTX5 is osRtxErrorNotify. See https://www.keil.com/pack/doc/CMSIS/RTOS2/html/group__rtx5__specific__functions.html#gaf1745a88f9cc60b609ab1c8076bd346d   You can also see the correct error notification codes there. You get all the definitions when you include #include "cmsis_os2.h"   into your source code as described in our manual.

Thanks a lot for your answer. I installed everything (Keil MDK + Tutorial) on a newly created virtual Win10 machine.
It worked much better, but I still get an error:

The include chain “rtx_kernel.c -> rtx_lib.h -> rtx_core_c.h -> rtx_core_cm.h” percolates the following problem in rtx_core_cm.h, lines 464 – 465:

 #if defined(__CC_ARM)
static __asm    uint8_t atomic_wr8 (uint8_t *mem, uint8_t val) {

The symblol ‘__asm’ is not recognized, the compiler says “error: expected identifier or ‘(‘”.

Kind regards, (too) Hans

PS: the reason behind this all is that I have to start a new Keil MDK project and I’m trying to use and get acquainted with RTX5. The old project which I inherited uses adapted code from an evaluation board.

I don't know exactly where this comes from, but it seems that there is a mismatch of the compiler versions. When you get an error message for this line, it means that the definition __CC_ARM is set. This is usually only set when the Arm compiler version 5 is selected. If this is the case, you should not get any errors. I assume, that you have selected the Arm compiler version 6 but maybe __CC_ARM is manually defined somewhere in your project. If you can't fix this issue, please tell me which versions of MDK, CMSIS and which Arm compiler you use (hint: MDK 5.35 was released yesterday, CMSIS 5.8.0 two days before). You could also create a support ticket with your project attached to it.

They might have more than one version installed?

1) Under Project -> Options For Target -> Target tab, on the top-right, I have "Use Default Compiler version 6"

2) In my project, When I open this file and go to line 464:
    C:\Keil_v5\ARM\PACK\ARM\CMSIS\5.8.0\CMSIS\RTOS2\RTX\Source\rtx_core_cm.h

#if defined(__CC_ARM)
static __asm    uint8_t atomic_wr8 (uint8_t *mem, uint8_t val) {

The static line is grayed out - as it should, because I am using compiler 6.
