Dear 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

In spite of the fact that the datasheets give the same flashregister access rules for both the F273 and F272 (direct addressing is not allowed), it works for the 273 and not for the 272. Thus when applying the rules completely, it works:
mov R0,#FCR0L
exts #0x08,#1
mov R2,[R0]
and R2,#0x0012
will give you if the flash is busy...
