Dear All,
I am trying to compile a firmware for the STM8L. I used STVD & Cosmic
(compiler) but want to switch to sdcc. I had made some small code changes
to get everything running and I feel it's compiling correctly. I am using
the following cmd to compile:
sdcc -lstm8 -mstm8 -I inc -I ../../Source/inc -I
../../Libraries/STM8L15x_StdPeriph_Driver/inc -I
../../Libraries/STM8L-discovery_Libraries/inc -D STM8L15X_MD -D __CSMC__
--opt-code-size --disable-warning 126 src/main.c
(warning 126 is about unreachable code, I have to define __CSMC__ [Cosmic
compiler] because my project was created with STVD which only supports 3
compilers [otherwise, I would need to change a lot of header files]; my MCU
is STM8L152C8)
As I said, it compiles, but generates the following warnings:
?ASlink-Warning-Undefined Global '_RTC_SetWakeUpCounter' referenced by
module 'main'
?ASlink-Warning-Undefined Global '_GPIO_Init' referenced by module 'main'
?ASlink-Warning-Undefined Global '_ADC_DeInit' referenced by module 'main'
?ASlink-Warning-Undefined Global '_RTC_WakeUpCmd' referenced by module
'main'
?ASlink-Warning-Undefined Global '_FLASH_ProgramOptionByte' referenced by
module 'main'
?ASlink-Warning-Undefined Global '_ADC_ChannelCmd' referenced by module
'main'
?ASlink-Warning-Undefined Global '_RTC_ITConfig' referenced by module 'main'
?ASlink-Warning-Undefined Global '_ADC_GetFlagStatus' referenced by module
'main'
?ASlink-Warning-Undefined Global '_CLK_PeripheralClockConfig' referenced by
module 'main'
?ASlink-Warning-Undefined Global '_FLASH_EraseOptionByte' referenced by
module 'main'
?ASlink-Warning-Undefined Global '_RTC_WakeUpClockConfig' referenced by
module 'main'
I am not very experienced and I don't know whether this should be a problem
or not. main.map contains:
...
ASxxxx Linker V03.00 + NoICE + sdld, page 1.
Hexadecimal [32-Bits]
Area Addr Size Decimal
Bytes (Attributes)

bytes (ABS,CON)

----- -------------------------------- ------------------------
00000000 _ADC_ChannelCmd
00000000 _ADC_DeInit
00000000 _ADC_GetFlagStatus
00000000 _CLK_PeripheralClockConfig
00000000 _FLASH_EraseOptionByte
00000000 _FLASH_ProgramOptionByte
00000000 _GPIO_Init
00000000 _RTC_ITConfig
00000000 _RTC_SetWakeUpCounter
00000000 _RTC_WakeUpClockConfig
00000000 _RTC_WakeUpCmd
...
Greping for these keywords tells me that these are function names (without
the prefixing underscore) in the STM8L libraries (inside my project). So
they are there and I feel I just need a small change in order to prevent
this problem.
So, to sum up:
#1 Does anyone know about this problems and how to deal with it?
#2 I don't know whether I can flash my MCU and just check if it still works
(as I said, I am inexperienced and I fear to damage the chip with a faulty
firmware)
#3 I am not sure, whether I need to use packihx or not. The sdcc manual
states the the default output is already the Intel Hex format (which I used
previously).
Last but not least: You guys rock! I am really thankful for your project :)
Thanks in advance,
Rolf
