I’m trying to run the FreeRtos demo port for Energy Micro EFM32G890F128 board.
The code newer succeeds to start tasks scheduling. Actually, it hangs up forever  on SVC_Handler called from the vPortStartFirstTask.
Does any body had same problem?
(I use the FreeRtos port  without any changes., although I had to change the project to use more updated Energy Micro code.)
Thanks a lot,
Julia

In which case you have probably replaced the vector table.  Take a look at number one here: http://www.freertos.org/FAQHelp.html Regards.
