hi,

i am working on FRDMK64 controller. i am using KDS3.0 and KSDK1.2.0 example. my controller have 1MB flash and 256kb RAM.i am working on internal data flash read/write example.

i have some doubts in following function

 

1)what is the use of CACHE_DISABLE

2) g_FlashLaunchCommand = (pFLASHCOMMANDSEQUENCE)RelocateFunction((uint32_t)ramFunc , LAUNCH_CMD_SIZE ,(uint32_t)FlashCommandSequence);

in this function can i increase LAUNCH_CMD_SIZE  to 0x200. and also what is the use of above function and LAUNCH_CMD_SIZE  .

3)in my application code i am trying to write data from 0x8000 to 0xFA000 address but its not working correctly. upto 0x80000 address only its working fine.  i mean upto(512kb).

 

can you give some solution for this.
