OS_TIME signed variable?

Hi Martin, we are using signed time values and calculate timeouts with subtractions. This make it's easy to handle overflows which means all timing functions just works (even if there is an overflow). Quoted I always need to check for timer overflows myself when working with time differences?! No, you don't have to check anything by yourself. You can just use embOS API like e.g. OS_Delay() and it will always works. Best regards, Til

Cortex M3 Peripherals SVD File?

I think what you are looking for is the ARMCM3.svd file which can be found in the CMSIS-core package. Please have a look here: https://www.arm.com/products/processors/…ce-standard.php

unsupported debug_info format

Hi Rolf, embOS Cortex-M IAR V8 is only for IAR EWARM V8. It cannot be used with IAR EWARM V6/V7. For IAR EWARM V6/V7 please use embOS Cortex-M IAR V6. Best regards, Til

Can OS_TASK_EVENT be 64-bit unsigned on 32-bit ARM Cortex-M?

Hi Scott, basically that should be doable since we already disable the interrupts while modifying the task event bit mask. You will need to define OS_TASK_EVENT as a 64 bit unsigned in e.g. your project settings while working with the embOS sources. But please contact us directly by email. That makes it easier to discuss the details. Best regards, Til

CMSIS-rtos interface to embOS

Hello, we already implemented the CMSIS RTOS layer. But this layer has a lot of disadvantages in comparison to our embOS API. Please contact us directly for further information. Best regards, Til

embOS for Cortex-M with IAR 8.10.1

HI, IAR changed the TLS support with IAR EWARM V8. Thus some minor modifications in embOS are necessary. We will release an updated embOS version in the next week. Best regards, Til

embOS Simulator Stimuli

HI Benjamin, the embOS Simulation simulates 100% the embOS API and can be adapted to your requirements. It is possible to use the complete Windows API inside the simulation, thus you can easily communicate with other applications or hardware. I am not sure if I understood the last question correctly but I guess it's about using the same application in simulation and target hardware? Please be aware only the embOS API is simulated but not e.g. the STM32 peripherals. Anyhow we can help you to setu...

no definition for "OS_ConvertCycles2us" when calling OS_STAT_GetLoad

Hello, OS_ConvertCycles2us() is part of the RTOSinit.c All our shipped RTOSInit.c include this function. Please contact us via our support email address with your embOS license number and which board support package or exact device/evalboard you are using. We will send you then everything you will need. Best regards, Til

Using openVG with embOS

Hi Alan, one additional note: With embOS and RZ the memory managment unit and caches are used. Please find at the end of RTOSInit_R7S72100.c the MMU table which defines which memory areas are cached with write through or write back. If you are using the wrong setting it could happen that e.g. the display data is only written to the cache but not directly written to the memory. Best regards, Til

How to debug RTOS

Could you please give us more information about your setup? Which embOS and which embOS version do you use? Which compiler and IDE ? Which debug probe? Are you working with embOS library or embOS source code? I don't think there is something wrong with embOS. If you can't debug the code this is more related to your IDE and/or debug tools. If you have a valid embOS license you can also contact us directly per email. Best regards, Til

emWin memory management bug. ...Ex() functions.

Quoted As STM said, STemWin is emWin library that they licensed from segger for its customers. This means, that every time I buy MCU from STM, I indirectly pay to STM for emWin library. That is why STM's MCUs cost twice as much than LPC's for example. STM provides emWin manual with STemWin library. All functions look completelly the same. Sure, from the technical side STemWin and emWin are the same but not from the license side. When you buy a ST CPU you get a free license of STemWin and not fo...

emWin memory management bug. ...Ex() functions.

Quoted Last time I appealed to this forum, support engineer Til, just tried to pick me on some details in my code and makes demagogy about commercial relationships. Dear Constantine, please be aware we are a commecial company which gives support via email to our customers which have a valid software license. You don't have an emWin license and your are not an emWin customer. Therefore I tried to explain you that you are using STemWin and not emWin. The differnce is the commercial relationship. ...

...Ex() functions and FreeRTOS on STM32

Hi Constantine, Quoted This definetly BUG in function. Nope. There is no bug in that function. Did you had a look in the chapter "Execution Model: Single Task / Multitask" in the emWin manual? Did you add the according FreeRTOS functions? Quoted Description of function IMAGE_SetBMPEx in manual is poor. No any examples can be found. The IMAGE_SetBMPEx() description refers to the GetData description and there are several examples: Pointer to the GetData()-function. Details on how to implement a Ge...

OS_Start causes OS_Error code OS_ERR_STACK

Dear Veronica, I just checked the board support package and I can build and run the K60 start project without any problems. The error message says a task stack overflowed but I guess in your case this is caused by something else. Did you make any modifications to the sample application or the start project? Which Keil MDK version do you use? I used Keil MDK V5.20. Which evalboard do you use? Please don't hesitate to contact us directly via our embOS support email address. You can find the embOS ...

resume before suspend on heavy CPU load

Dear Christian, Quoted Do you offer embOS (advanced) trainings? Yes, of course! An embOS training is usually a one day event which can be held at our training facility or at your location. We teach in an embOS training not only the RTOS basics and explain the API but also discuss how embOS can be used in your actual application. Please contact us per email/phone for further information. Best regards, Til

Remove JLinkMem Dependency

Hi Kenny, actually the linker error message is capable of being misunderstood because OS_JLINKMEM_BufferSize is not used in OS_SetPRIMASK() but at other places in the RTOS.asm. Setting it to zero is the correct solution as long as you have the object code version only. With the source code version you could remove it completely but that is not necessary. Please be aware it is not guaranteed that we answer here in a short time (or at all). Since you have a valid embOS license please use the suppo...

Remove JLinkMem Dependency

Hi Kenny, OS_SetPRIMASK() does not use OS_JLINKMEM_BufferSize at all. Did you get this as a linker error message? You can completey remove OS_JLINKMEM_BufferSize only with the embOS source version but if you don't want to use the J-Link Buffer you can just disable the embOSView communication in the RTOSInit.c This is already done in the Release configuration. Please don't hesitate to contact us directly per email. You can find the embOS support email address in chapter "Support" of the embOS man...

EMBOS TCP/IP Options

Hi Kenny, thanks for your thoughts but we will not provide a LWIP port, of course. We have our own TCP/IP stack which is much more reliable and efficient than such a non commercial project. To be honest we sell more than enough embOS license since meanwhile it is de facto standard for embedded products . The problem with such non commercial projects like FreeRTOS or LWIP is that you need much work time to get it up and running. I think nobody works for free and in the end you pay more than for t...
