My configuration is under S32K Design Studio.

After Build, I encounter below build error...

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

S32K144-100 with FreeRTOS via Processor Expert.

Hi,

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

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....

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 !

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.
