Posted on November 17, 2017 at 09:45Hi,everyone!
I did a stm32f103 firmware download application run on Windows system recently,and I found that there is about 1% of MCU can not download success and can not download again.Following is part of my code,hope that you can point my code bug out:
char
g_szPrgBoard[
50
]
=
'ST-LINK'
;
char
g_szPrgProtocol[
50
]
=
'SWD'
;
char
g_szPrgDevice[
50
]
=
'STM32F103x8'
;
char
g_szPort[
50
]
=
'USB'
;
char
ProgMemFileName[_MAX_PATH]
=
'tx.hex'
;
char
OptionMemFileName_off[_MAX_PATH]
=
'103_protect_off.hex'
;
char
OptionMemFileName_on[_MAX_PATH]
=
'103_protect_on.hex'
;
unsigned
char
dOpttemp_on
=
0
,dProtemp
=
0
,dOpttemp_off
=
0
;
if
(
SetProgrammingConfiguration
(g_szPrgBoard,g_szPrgProtocol,g_szPrgDevice,g_szPort)
==
TRUE
){
ESetPreferences
(PROTECTION_WARNING,
FALSE
);
if
(
LoadFile
(OptionMemFileName_off,
'OPTION BYTE'
)
!=
TRUE
){
dOpttemp_off
=
1
;
}
if
(
Program
(
'OPTION BYTE'
)
!=
TRUE
){
dOpttemp_off
=
1
;
}
if
(
Erase
(
'PROGRAM MEMORY'
,g_szPrgDevice)
!=
TRUE
){
dProtemp
=
1
;
}
if
(
FillImageMemory
(g_szPrgDevice,
'PROGRAM MEMORY'
)
!=
1
){
dProtemp
=
1
;
if
(
LoadFile
(ProgMemFileName,
'PROGRAM MEMORY'
)
!=
TRUE
){
dProtemp
=
1
;
}
SetByteInImageMemory
(g_szPrgDevice,
'PROGRAM MEMORY'
,
0x800F020
,
0x05
);
SetByteInImageMemory
(g_szPrgDevice,
'PROGRAM MEMORY'
,
0x800F030
,
0x02
);
SetByteInImageMemory
(g_szPrgDevice,
'PROGRAM MEMORY'
,
0x800F040
,
0x05
);
if
(
Program
(
'PROGRAM MEMORY'
)
!=
TRUE
){
dProtemp
=
1
;
}
if
(
Verify
(
'PROGRAM MEMORY'
)
!=
TRUE
){
dProtemp
=
1
;
}
ECloseComm
();
}
