Selected Processor does not support in THUMB Mod

[yumjeongwon]

My configuration is under S32K Design Studio.

After Build, I encounter below build error...

------------------------------------------------------------

S32K144-100 with FreeRTOS via Processor Expert.

You can also try to modify the port.c file, at the xPortPendSVHandler method. The assembler instructions "vstmdbeq" and "vldmiaeq" cannot be compiled with Library Soft option (-mfloat-abi=soft)
Attached you can find the modified file, more specifically you can find the changes on lines: #451, #456, #475, #479.

Hi, we have the same error  

Error instruction not allowed in IT block -- `msr psp,r0' 
Error instruction not allowed in IT block -- `stmdb r0!,{r4-r11,r14}

We are using the ATSAM4SD32C with Atmel Studio but the chip has no hardware float point support. I have tried -mfloat-abi=soft.  Does anybody have an idea how we can solve this, we are stuck with this problem....

Hi, 

you need to enable hardware float point support in project properties (right click on project name):

Sorry jiri_kral,

If controller has the FPU, it needs to be enable when project using FreeRTOS. Is that right ?

And why we need enable FPU when project using FreeRTOS ?

Thank you !
