Header of "kernel loader" is on 0x00000000 of Flash (physical addr: 0xfff00000)
in size of 0x20 with CHK
---------------------------
0x5a ;Header ID
04,0,0 ;?
0xd,0xc,0,0 ;=0x00000c0d size of "kernel loader" + CHK
0xc,0xc,0,0 ;=0x00000c0c size of "kernel loader"
0x20,1,0,0 ;=0x00000120 start of "kernel loader" data in FLASH (physical addr 0xfff00120)
0x80,0xa,1,0 ;=0x00010a80 physical addr where "kernel loader" have to be loaded
0x80,0xa,1,0 ;=0x00010a80 physical addr of execute start once "kernel loader" is loaded
0,0,0 ;?
0xd1 ;Header ID CHK 8-bit cheksum of first 0x1f bytes of "kernel loader" header

For this case bootstrap loads "kernel loader" to addr: 0x0x00010a80 in size 0x00000c0c
calculate 8 bit cheksum and compare with next byte (offset + 0x00000c0c)
