Retaining a program in flash after debug.

eitanmichaelson — Mon, 30 Oct 2017 15:29:50 GMT

Hello,

Just got the the 54608 ev board, I have the latest MCUXpresso IDE along the latest SDK for the board.

I've imported the simplest sample I could find (gpio_led_output) , compiled clicked debug and .. It worked as expected.

However, once the debugger was detached the board went to its previous state, as if the program was executed from RAM. How can I forced the software to be retained after debug is over ?

Please, don't crucify me, I'm new to this specific board and didn't have the time to through all of the PDFs.

10x,

Hello Eitan,

Please check the "Redirrect print/scanf to UART" when import SDK project :

I t will download to flash.

When open SDK project, the default configuration is print to console using C lib, in this

Way, the project can’t download to FLASH.

Have a great day,
TIC

Thank you very much for your help.

This problem happened to me and I have thought that It was related to the RTOS or baremetal, because an example of LPCOpen continue working and retaining the code after debug.

Hi Alice,

I know this thread has been here a while ago, but today I have similar problem and I need your help if you can.

I use KDS ver 3.2.0 and a Segger J-link debug probe to download the code into my board. The code is running fine until I removed the cable and power off the board. When the power is applied again to the board, the micro was up but the program never ran. It seems the program was lost or wasn't programmed into flash as intended.

I posted my issue in this thread:

Would you mind giving your opinion on my issue? I'd appreciate it.

Thanks,

Daniel Truong
