Posted on September 03, 2008 at 16:51Dear all,
Can anybody explain why the code below works
for a ST10F273z4 and the same code, adjusted
for the F272, does not work?
(it programs the ecu-serial number from the
kline-buffer to the flash (in B0F1))
F273 code:
; Select DWPG
mov R1,#0x1080
exts #0x0E,#1
mov FCR0H,R1
; Set data
mov RL1,Kline_message_buffer+7
mov RH1,Kline_message_buffer+8
exts #0x0E,#1
mov FDR0L,R1
mov RL1,Kline_message_buffer+9
mov RH1,Kline_message_buffer+10
exts #0x0E,#1
mov FDR0H,R1
mov RL1,Kline_message_buffer+11
mov RH1,Kline_message_buffer+12
exts #0x0E,#1
mov FDR1L,R1
mov R1,#0xFFFF
exts #0x0E,#1
mov FDR1H,R1
; Set address
mov R2,#1 ; Msw of address = 1!!!
mov R1,#F_ecu_serial_number
exts #0x0E,#2
mov FARL,R1
mov FARH,R2
; Set WMS
exts #0x0E,#1
mov R2,FCR0H
or R2,#0x8000
exts #0x0E,#1
mov FCR0H,R2
waitfornolock3:
exts #0x0E,#1
mov R2,FCR0L
jb R2.4,waitfornolock3
jb R2.5,waitfornolock3
F272 Code:
; Select DWPG
mov R1,#0x1000
exts #0x08,#1
mov FCR0H,R1
; Set data
mov RL1,Kline_message_buffer+7
mov RH1,Kline_message_buffer+8
exts #0x08,#1
mov FDR0L,R1
mov RL1,Kline_message_buffer+9
mov RH1,Kline_message_buffer+10
exts #0x08,#1
mov FDR0H,R1
mov RL1,Kline_message_buffer+11
mov RH1,Kline_message_buffer+12
exts #0x08,#1
mov FDR1L,R1
mov R1,#0xFFFF
exts #0x08,#1
mov FDR1H,R1
; Set address
mov R2,#1 ; Msw of address = 1!!!
mov R1,#F_ecu_serial_number
exts #0x08,#2
mov FARL,R1
mov FARH,R2
; Set WMS
exts #0x08,#1
mov R2,FCR0H
or R2,#0x8000
exts #0x08,#1
mov FCR0H,R2
waitfornolock3:
exts #0x08,#1
mov R2,FCR0L
jb R2.4,waitfornolock3
jb R2.1,waitfornolock3
Anybody any hints?
Regards, Folkert
