programming flash using .elf file

ava — Wed, 11 Mar 2015 04:35:48 GMT

Hello Everyone,

I am using MK60FX512 controller, CW10.6 & MQX4.1.

Also I am using FlexEEPROM (did the partition).

If I programmed the flash with .elf file through flash programmer, flash is programmed successfully but application code doesn't execute.

and if I programmed flash with another .elf file (the code without EEPROM),application code runs successfully.

Please help me to resolve this problem.

Thanks.

Hello Everyone,

As per my previous (above) post I have checked that through debug in MQX4.1 FlexNVM is partitioned for EEPROM backup & D-flash but the same .s19 file if I programmed through flash programmer, through flash programmer FlexNVM is not partitioned for EEPROM backup & D-flash. Controller is getting reset everytime.

I have tested with processor expert and through debug & flash programmer able to partition device for flexEEPROM backup & D-flash.

Please help me to solve this.

Thanks.

Hi Carlos,

Thanks for your reply.

As per the post Re: Partitioning of Kinetis K50 with PE Multilink Universal

it is said its not possible to do partitioning using flash programmer we have to do it in application code.

I have already done it in my application code,but once it runs the partitioning code due to OS interrupts controller is reset because of this reason I am not able to do partitioning through application code, then I used disable interrupt routine as below and my code worked properly through flash programmer also.

__disable_interrupt();

error = Cpu_SetFlexNVMPartition();

Cpu_SetFlexRAMFunction(FlexRAM_AS_EEPROM);

__enable_interrupt();

I am not sure that should I use enable/disable interrupt since it disables the OS interrupt.

Please let me know is it ok to use enable/disable interrupt routines

Thanks.

Hi Carlos,

Please let me know should I use interrupt disable / enable routines or there is any other way to partition FlexNVM through flash programmer.

Thanks.

Hello T tech,

Yes, you should use those functions to mask any possible core accesses to vector table or interrupt service function in flash, we recommend to keep to a minimum the code between these calls.

Another way for partitioning the Flash is to use the CodeWarrior debugger which includes a command to partition the flash.

Hope it helps!
