Why Altera MPL (Minimal Preloader) build error with ARMCC ?

Altera_Forum · ‎01-09-2015

Follow the instruction of C:\altera\14.1\embedded\examples\software\Altera-SoCFPGA-HardwareLib-MPL\README.txt.

I am using Cyclone V SoC Dev Kit, in comfig.mk, I modified content as below:

BOOT_SOURCE := QSPI

DEVICE := C5

COMPILER := gnu

I am using DS-5 to import this example (C:\altera\14.1\embedded\examples\software\Altera-SoCFPGA-HardwareLib-MPL)

Build project is successful.

But when I set

COMPILER := arm

then get compile error as below:

I was told that this is a known issue and the workaround is to comment out the assembly code at the top of sequence.c
