Why RAM overflow?

[jianfengzheng]

freescale:

I use MK22FX512VLQ，also implement ProcessorExpert

when adreess of RAM exceed to 0x1FFFFFFF，Link fails,  the Console output says m_data overflowed, as following

But I know the RAM space end-address is 0x20007FFF，Why is the space m_data_20000000 not available? 

Please tell me how to set Build Options of PE or others.  Thank you!

Further more, I modified the _estack to x20008000 in ProcessorExpert.ld, but it is no use。below is the cut of screen.

Hello JianFeng,

- For some data section ".data" ".bss".. default save int the "m_data",

not the MEMORY of "m_data_20000000", you can relocate some data or code into

this MEMORY section , refer to this DOC :

Relocating Code and Data Using the KDS GCC Linker File for Kinetis 

- If you only want the project without error , not overflowed , simply, you can

merge the two section to one named "m_data" . Only need change here as the screenshot,

then generate code , build .

then you can see the linker file :

Hope it helps

Have a great day,
Alice
