150 FX3 Programmers Manual, Doc. # 001-64707 Rev. *C
FX3 Boot Image Format
dLength 0 2
1st section length, in long words (32-bit)
When bImageType=0xB2, the dLength 0 will contain PID and VID. Boot Loader will ignore
the rest of the any following data.
dAddress 0 2
1st sections address of Program Code not the I2C address.
Note
Internal ARM address is byte addressable, so the address for each section should be 32-
bit align
dData[dLength 0]
dLength
0*2
All Image Code/Data also must be 32-bit align
… More sections
dLength N 2 0x00000000 (Last record: termination section)
dAddress N 2
Should contain valid Program Entry (Normally, it should be the Start up code i.e. the
RESET Vector)
Note
if bImageCTL.bit0 = 1, the Boot Loader will not transfer the execution to this Program
Entry.
If bImageCTL.bit0 = 0, the Boot Loader will transfer the execution to this Program Entry:
This address should be in ITCM area or SYSTEM RAM area
Boot Loader does not validate the Program Entry
dCheckSum 2
32-bit unsigned little endian checksum data will start from the 1
st
sections to termination
section. The checksum will not include the dLength, dAddress and Image Header
Binary Image
Header
Length
(16-bit)
