Thank You everyone for the support.

Uninstalling components from Simplicity Studio didn't solve the problem.

I uninstalled Simplicity Studio and reinstalled it. Now Micrium OS is updated to latest version.

@Alex Lipskiy,

Can you advice me how to delete current Micrium OS version?

I've deleted the Micrium OS folder from C:\SiliconLabs\SimplicityStudio\v5\developer\sdks\gecko_sdk_suite\v3.0\platform but I still can't install/update.

@jpitt,

I'd restarted Simplicity Studio 5 and tried to update several times but to no success. I'd even restarted my PC but still getting the same error. I've even tried to update Micrium OS after starting simplicity studio in administrator mode but still getting the same error.

I'm trying to update the 32-bit MCU SDK and Micrium OS  in simplicity studio 5. 32-bit MCU SDK is getting updated successfully.

I'm getting error INVALID_SERVICE StudioService : no access allowed to this class when I try update Micrium OS.

I've attached screenshots of the entire process.

I'm using the UARTDRV library to send and receive data on USART4 (J-Link Virtual COM) - EFM32GG11 Board. I'm testing an echo program (i.e.  transmitting back the data that I've received).

I'm able to transmit data without any problem (which I verified independently) but I'm facing issues while receiving data.

As the UARTDRV_Receive doesn't offer timeout functionality and I don't know the size of my data in advance; I'm reading one byte at a time.

While receiving I've found that the first character read is wrong (e.g. if the first character sent was 'I' but the character read was '@'), next few characters are read properly and then the driver stops receiving data.

e.g. String sent to EFM32GG11 Ibuprofen but data received @bupr

I tried calling the UARTDRV_GetReceiveStatus  function but the itemsRemaining parameter returns 0.

@luweiguo, thanks for the support.

Their was some problem with my original installation as I couldn't find the sl_sleeptimer.h anywhere.

I uninstalled Simplicity Studio and reinstalled it and was able to find the file, whose directory I added in my include file directory path.

As suggested I added necessary folder in my include path.

I'm Getting error :

fatal error: sl_status.h: No such file or directory    serial_port_test        line 51, external location: D:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v2.7\platform\service\sleeptimer\inc\sl_sleeptimer.h    C/C++ Problem
