I am using MKL27Z128 and need to be able to program the last 4 bytes of flash (0x1FFFC to 0x1FFFF). I am using the KinetisFlashTool ver 22.214.171.124 downloaded in NXP_Kinetis_Bootloader_2_0_0. Whenever any s-record in my file contains an address greater than 0x1FC00, I get the following error message:
Erase all memory of internal flash and unsecore the device. Completed!
Device information is updated!
Start update progress......
Error: Update image failed(kStatus_FlashAddressError).
Update process is stopped by error.
