I compiled FreeRTOS with cmake + make for stm32f722 (cortex-m7), however, when I run it on my device, it gets stuck on the "vPortRaiseBASEPRI" function from portmacro.h. I've attached the disassembly below. It looks like the disassemble has a lot of jumps to the same line? What could be the problem here?
the file is from portable\GCC\ARM_CM7\r0p1

I forgot to add, I'm using arm-none-eabi toolchain and here's the compile options
-mcpu=cortex-m7 -march=armv7e-m -mthumb -mfpu=fpv5-sp-d16 -mfloat-abi=hard -0g -g -O3 -fdata-sections -ffunction-sections
The assembly code bares no resemblance to the source code, especially as the source function is written in assembly. For that reason I am confident this is not a FreeRTOS bug. Please create a support request on https://forums.freertos.org and we can help diagnose for you. Additionally, SourceForge is no longer our primary repository. Please see https://github.com/freertos
Okay, I'll create a request there. Though, I can't figure out how to create a topic at the new forum. Pressing 'c' doesnt open the composer.
