Posted on May 17, 2011 at 09:41hello Raj,
some remarks to your project what is different to mine
1.) you use the ST-LIB as binary lib file
i use direct the C- and H-files from the ST-LIB in the project (using own folder),
that is better for changing something what you need (see 2.)) and for the optimizer,
the #define DEBUG from the ST-LIB I've never used
2.) if you have remapped the STR912 (run code from bank 1 at address 0)
then you need also remap the ST-LIB, the code in 91x_fmi.h and 91x_fmi.c
search for the word ''Remap_Bank_1'' in the c and h files,
you have to set a global #define Remap_Bank_1 for the complete project !!!!
3.) writing to the flash is only possible (on my experience)
with a lower clock frequency (PLL off) with 25 Mhz. That's why my bootloader
is running with 25 Mhz and the PLL is switched later on to 96 Mhz if I start
start the project running in bank 0 (512 KByte).
4.) in your main programm you have
SCU_AHBPeriphClockConfig(__FMI, ENABLE);
SCU_AHBPeriphReset(__FMI, DISABLE);
from my opinon every programm on the STR912 start at address 0 from the flash (FMI),
that means, the clock for the flash is per hardware default every time active, and you have not
touch the clock for the FMI, so long you don't run software from RAM !
5.) the address for the non boot bank in ''STR91x Bank1.s'' is definitive wrong.
you have to use addresses like 0x80000, 0x100000, 0x180000, 0x200000, ....,0x400000 which are
a multiply of 512 KByte = 0x80000. I use 0x400000.
thats all for the first time, hoping I can help you
Best regards
B.
P.S.: please correct me if i'm wrong on some points, this will also help the others and me
