Cortex-A8 boot up cpsr status

Hi,

I have a beaglebone black and running a very basic app using starterware. As soon as the app starts executing i copy the CPSR values in memory. The value of CPSR is super surprising

6000019f

which means it is in SYS mode and IRQ, ABORT disabled and FIQ enabled.

i read in the PG that

A processor enters Supervisor mode on Reset.

Really confused

Here is my code for reference

	MRS r0, CPSR
	LDR r1,=0x800a0000
	STR r0, [r1]
	ADD r0, r0, #1
	LDR r1,=0x800a0004
	STR r0, [r1]
	LDR r0, =0xDEADBEEF
	LDR r1,=0x800a0008
	STR r0, [r1]

Hi maos,
You are correct. I slept over it and first thing in the morning i realized about the bootloader and the rom code. Will verify that today, thanks!
