I have a problem in the MCU MK22FX512VLL12, the next document "K22 Sub-Family Reference Manual", mention that the memory SRAM is the size of 128 KB.

However, the linker file makes the next table. I am using Kinetis Desing Studio.

seems that this MCU only has a size of 64 KB in SRAM.

I am using the next version of the linker file

Someone, know why happen this?

Hi Emmanuel,

Yes, this problem is so strange. Please modify the link file to

m_data      (RW) : ORIGIN = 0x1FFF0000, LENGTH = 0x00010000

 m_data_2  (RW) : ORIGIN = 0x20000000, LENGTH = 0x00010000

Regards,

Jing
