Hi everyone,

I use MCUXpresso IDE (V11.2.1) to develop the function of KW38, and use feedom bootloader to boot the BLE application through the UART upgrade of KinetisFlashTool.exe tool, but I don’t know how to allocate the FALSH and RAM space of the BLE application to correspond to the FLASH of the feedom bootloader , RAM space can be upgraded by this method?

 

Freedom bootloader FLASH and RAM space are as follows:

BLE wireless_uart_bm FLASH and RAM space are as follows:

The names of FLASH and RAM, FEFT_2K.cfx, FEFT_2K_D.cfx, do not know what they mean, is there any relevant documentation?

"MCU Bootloader Demo Application User's Guide.pdf", I tried the examples inside, and it can be programmed normally as described in the document.

thank you very much!

Hi,

You do not modify the application's size. 

Have a great day,

Hi,

If your bootloader will go to address 0xa000, you can configure like this.

You should modify the application's Location and the size.
