Hi,

I know that this question was already asked and aswered in this forum but I can't find information that help me.

I want to move all my flash related code to ram so I can program/erase the bank0 (B0F7 to be exact).

I found this post :

http://www.st.com/mcu/forums-cat-4655-17.html

and I tried this solution, but RVDK tell me :

Quote:

''..\source\conf.c'', line 222: Error: #77-D: this declaration has no storage class or type specifier

__ramfunc void init_flash_write_tables(void)

... and this is obscur to me.

If someone can give me some info about that or point me where I can find them.

Thanks in advance

The code you are referring to was designed for IAR, you are using Keil.

Keil provide an example with their tools

http://www.keil.com/support/docs/3228.htm

Have a look at the RAM_Function example.

Thanks for the reply, but sadly I am not using Keil but Realview. So what I look for is the equivalent procedure to put code in ram with realview...

Keil and Realview are the same compiler/linker.

You just need to use a scatter file and place the required file into the ram section.

It is also mentioned somewhere in the realview docs aswell.

Also try a google search, may find more examples.

Thanks a lot Sjo, it work now.

It's simpler than I thinked, with all theses __ramfunc things that I saw when I was googling this problem
