About KL27Z32 this chip , Datasheet introduced it's SRAM capacity is 8KB, but I found it's capacity is 4KB in J-Link and IAR icf file called "32KB_Pflash.icf " , and I'm get in trouble to debug this chip , have a hard fault isr.

Hi lee Lionel,

KL27Z32 really have 8KB, the IAR icf file(MKL27Z32xxx4.icf) which can be found from the IAR install path :C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.2_2\arm\config\linker\Freescale

define the RAM as follows:

define symbol __ICFEDIT_region_IRAM1_start__ = 0x1ffff800;

define symbol __ICFEDIT_region_IRAM1_end__ = 0x1fffffff;

define symbol __ICFEDIT_region_IRAM2_start__ = 0x20000000;

define symbol __ICFEDIT_region_IRAM2_end__ = 0x200017ff;

It also have 8K RAM.

I don't know how did you find it is 4KB, and where your 32KB_Pflash.icf from.

Attached is the MKL27Z32xxx4.icf, you can refer to it.

You said you get in the hard fault isr, you can attach your project, then we can help you to check it.

Wish it helps you!

Have a great day,

Jingjing

Thank you , In J-link , It's only have 4KB RAM for MKL27Z32,.About the hard fault ,I already solved it.

Hi Lee,

I am not clear what do you mean“In J-link , It's only have 4KB RAM for MKL27Z32,” could you give me a relative picture?

Have a great day,
