A BUG when generate code for toolchain `makefile` or `cmake`.

My develop environment: Linux PC

 

After generated code, I run `make` and got errors:

```

/usr/lib/gcc/arm-none-eabi/7.3.1/../../../arm-none-eabi/bin/ld:STM32F103C8Tx_FLASH.ld:56: syntax error
collect2: error: ld returned 1 exit status

```

 

After my investigation, I found that the reason was that all the RAM symbols in this file were replaced with empty!

 

For example:

 

Line 56:    _estack = ORIGIN() + LENGTH(); /* end of RAM */

Should be:    _estack = ORIGIN(RAM) + LENGTH(RAM); /* end of RAM */

 

Line 146:     } > AT> FLASH

Should be:     } >RAM AT> FLASH

 

Here is the patch will fix the BUG:
