[Help] build MKV31F256VLH12 bootloader

nguyenhoainam24 — Thu, 04 Apr 2019 03:18:42 GMT

I'm newbie in 31f chip, I want to build freedom bootloader for MKV31f256. I have use sample from https://www.nxp.com/support/developer-resources/software-development-tools/mcuxpresso-software-and-tools/mcuboot-mcu-bootloader-for-nxp-microcontrollers:MCUBOOT?&tab=Design_Tools_Tab (Bootloader 2.0) and make some change for my MKV31F chip. But when compile it's fail. Anyone can help me to create and build this boot loader.

Thanks!

Hi Nguyen,

It seems you want to build freedom bootloader on MCUXpresso. Now there is no need to do it by yourself. Please download the new KSDK for FREEDOM-KV31. It has build the freedom_bootloader for you.

Regards,

Jing

There is a pre-built version here: http://www.utasker.com/kinetis/FRDM-KV31F.html

Thanks a lot. But I can not select MCU boot. it's require USB stack and my MKV31F is not available.

If you want to build it yourself download the open source uTasker project from GITHUB and configure its serial loader [config.h] with

#define FRDM_KV31F
#define SERIAL_INTERFACE
#define KBOOT_LOADER

and build with KDS, MCUXpresso, Keil, IAR, Green Hills, CooCox, GCC make file, Rowley or simulate the KV31 in Visual Studio.

Hi,

Please select MKV31F512 or FRDM-KV31F. They have mcu-boot.

Almost done, but I have error when change from KV31f512 to KV31f256. It's may be not enough memory or something like this.

Hi,

There is no need to change mkv31f512 to mkv31f256. Because they are only different in flash size.

Did you replace MKV31Fxxx_feature.h and MKV31Fxxx12.h?

nguyenhoainam24 — Thu, 11 Apr 2019 01:31:00 GMT

There are some defined symbol need to be change in properties->C/C++build->Settings->preprocessor, like CPU_MKV31F512VLL12. Didi you modify them?

Or can you send me your project?
